Matthews Asian Growth and Income Fund

FUND SUMMARY

Investment Objective

Long-term capital appreciation. The Fund also seeks to provide some current income.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of this Fund.

SHAREHOLDER FEES

(fees paid directly from your investment)

ANNUAL OPERATING EXPENSES

(expenses that you pay each year as a percentage of the value of your investment)

EXAMPLE OF FUND EXPENSES

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example of fund expenses, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 32% of the average value of its portfolio.

Principal Investment Strategy

Under normal market conditions, the Matthews Asian Growth and Income Fund seeks to achieve its investment objective by investing at least 80% of its net assets, which include borrowings for investment purposes, in dividend-paying common stock, preferred stock and other equity securities, and convertible securities as well as fixed-income securities, of any duration or quality, including high yield securities (also known as “junk bonds”), of companies located in Asia, which consists of all countries and markets in Asia, including developed, emerging, and frontier countries and markets in the Asian region. A company or other issuer is considered to be “located” in a country or a region, and a security or instrument is deemed to be an Asian (or specific country) security or instrument, if it has substantial ties to that country or region. Matthews currently makes that determination based primarily on one or more of the following criteria: (A) with respect to a company or issuer, whether (i) it is organized under the laws of that country or any country in that region; (ii) it derives at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed, or has at least 50% of its assets located, within that country or region; (iii) it has the primary trading markets for its securities in that country or region; (iv) it has its principal place of business in or is otherwise headquartered in that country or region; or (v) it is a governmental entity or an agency, instrumentality or a political subdivision of that

country or any country in that region; and (B) with respect to an instrument or issue, whether (i) its issuer is headquartered or organized in that country or region; (ii) it is issued to finance a project with significant assets or operations in that country or region; (iii) it is principally secured or backed by assets located in that country or region; (iv) it is a component of or its issuer is included in a recognized securities index for the country or region; or (v) it is denominated in the currency of an Asian country and addresses at least one of the other above criteria. The term “located” and the associated criteria listed above have been defined in such a way that Matthews has latitude in determining whether an issuer should be included within a region or country. The Fund may also invest in depositary receipts, including American, European, and Global Depositary Receipts.

The Fund attempts to offer investors a relatively stable means of participating in a portion of the Asian region’s growth prospects, while providing some downside protection, in comparison to a portfolio that invests purely in common stocks. The strategy of owning convertible bonds and dividend-paying equities is designed to help the Fund to meet its investment objective while helping to reduce the volatility of its portfolio. Matthews expects that the companies in which the Fund invests typically will be of medium or large size, but the Fund may invest in companies of any size. Matthews measures a company’s size with respect to fundamental criteria such as, but not limited to, market capitalization, book value, revenues, profits, cash flow, dividends paid and number of employees. The implementation of the principal investment strategies of the Fund may result in a significant portion of the Fund’s assets being invested from time to time in one or more sectors, but the Fund may invest in companies in any sector.

Principal Risks of Investment

There is no guarantee that your investment in the Fund will increase in value. The value of your investment in the Fund could go down, meaning you could lose money. The principal risks of investing in the Fund are:

Political, Social and Economic Risks of Investing in Asia: The value of the Fund’s assets may be adversely affected by political, economic, social and religious instability; inadequate investor protection; changes in laws or regulations of countries within the Asian region (including countries in which the Fund invests, as well as the broader region); international relations with other nations; natural disasters; corruption and military activity. The economies of many Asian countries differ from the economies of more developed countries in many respects, such as rate of growth, inflation, capital reinvestment, resource self-sufficiency, financial system stability, the national balance of payments position and sensitivity to changes in global trade.

Currency Risk: When the Fund conducts securities transactions in a foreign currency, there is the risk of the value of the foreign currency increasing or decreasing against the value of the U.S. dollar. The value of an investment denominated in a foreign currency will decline in U.S. dollar terms if that currency weakens against the U.S. dollar. While the Fund is permitted to hedge currency risks, Matthews does not anticipate doing so at this time. Additionally, Asian countries may utilize formal or informal currency-exchange controls or “capital controls.” Capital controls may impose restrictions on the

Fund’s ability to repatriate investments or income. Such controls may also affect the value of the Fund’s holdings.

Risks Associated with Emerging and Frontier Markets: Many Asian countries are considered emerging or frontier markets (newer or less developed emerging markets are also sometimes referred to as frontier markets). Such markets are often less stable politically and economically than developed markets such as the United States, and investing in these markets involves different and greater risks. There may be less publicly available information about companies in many Asian countries, and the stock exchanges and brokerage industries in many Asian countries typically do not have the level of government oversight as do those in the United States. Securities markets of many Asian countries are also substantially smaller, less liquid and more volatile than securities markets in the United States.

Depositary Receipts Risk: Although depositary receipts have risks similar to the securities that they represent, they may also involve higher expenses and may trade at a discount (or premium) to the underlying security. In addition, depositary receipts may not pass through voting and other shareholder rights, and may be less liquid than the underlying securities listed on an exchange.

Volatility Risk: The smaller size and lower levels of liquidity in emerging markets, as well as other factors, may result in changes in the prices of Asian securities that are more volatile than those of companies in more developed regions. This volatility can cause the price of the Fund’s shares to go up or down dramatically. Because of this volatility, this Fund is better suited for long-term investors (typically five years or longer).

Convertible Securities Risk: The Fund may invest in convertible preferred stocks, and convertible bonds and debentures. The risks of convertible bonds and debentures include repayment risk and interest rate risk. Many Asian convertible securities are not rated by rating agencies. The Fund may invest in convertible debt securities of any maturity and in those that are unrated, or would be below investment grade (referred to as “junk bonds”) if rated. Therefore, credit risk may be greater for the Fund than for other funds that invest in higher-grade securities.

Growth Stock Risk: Growth stocks may be more volatile than other stocks because they are more sensitive to investor perceptions of the issuing company’s growth potential. Growth stocks may go in and out of favor over time and may perform differently than the market as a whole.

Dividend-Paying Securities Risk: The Fund may invest in dividend-paying equity securities. There can be no guarantee that companies that have historically paid dividends will continue to pay them or pay them at the current rates in the future. The prices of dividend-paying equity securities (and particularly of those issued by Asian companies) can be highly volatile. In addition, dividend-paying equity securities, in particular those whose market price is closely related to their yield, may exhibit greater sensitivity to interest rate changes. The Fund’s investment in such securities may also limit its potential for appreciation during a broad market advance.

Credit Risk: Credit risk refers to the risk that an issuer may default in the payment of principal and/or interest on an instrument.

Interest Rate Risk: Fixed-income securities may decline in value because of changes in interest rates. Bond prices generally rise when interest rates decline and generally decline when interest rates rise.

High Yield Securities Risk: High yield securities or unrated securities of similar credit quality (commonly known as “junk bonds”) are more likely to default than higher rated securities. These securities typically entail greater potential price volatility and are considered predominantly speculative. Issuers of high yield securities may also be more susceptible to adverse economic and competitive industry conditions than those of higher-rated securities.

Risks Associated with Medium-Size Companies: Medium-size companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss.

Risks Associated with Smaller Companies: Smaller companies may offer substantial opportunities for capital growth; they also involve substantial risks, and investments in smaller companies may be considered speculative. Such companies often have

limited product lines, markets or financial resources. Securities of smaller companies may trade less frequently and in lesser volume than more widely held securities and the securities of smaller companies generally are subject to more abrupt or erratic price movements than more widely held or larger, more established companies or the market indices in general.

Risks Associated with China and Hong Kong: The Chinese government exercises significant control over China’s economy through its industrial policies, monetary policy, management of currency exchange rates, and management of the payment of foreign currency-denominated obligations. Changes in these policies could adversely impact affected industries or companies in China. China’s economy, particularly its export-oriented industries, may be adversely impacted by trade or political disputes with China’s major trading partners, including the U.S. In addition, as its consumer class continues to grow, China’s domestically oriented industries may be especially sensitive to changes in government policy and investment cycles. If China were to exert its authority so as to alter the economic, political or legal structures or the existing social policy of Hong Kong, investor and business confidence in Hong Kong could be negatively affected and have an adverse effect on the Fund’s investments.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example of fund expenses, affect the Fund’s performance.

Principal Investment Strategy

Under normal market conditions, the Matthews Asia Dividend Fund seeks to achieve its investment objective by investing at least 80% of its net assets, which include borrowings for investment purposes, in dividend-paying equity securities of companies located in Asia. The Fund may also invest in convertible debt and equity securities of any maturity and quality, including those that are unrated, or would be below investment grade if rated, of companies located in Asia. Asia consists of all countries and markets in

Asia, and includes developed, emerging, and frontier countries and markets in the Asian region. A company or other issuer is considered to be “located” in a country or a region, and a security or instrument is deemed to be an Asian (or specific country) security or instrument, if it has substantial ties to that country or region. Matthews currently makes that determination based primarily on one or more of the following criteria: (A) with respect to a company or issuer, whether (i) it is organized under the laws of that country or any country in that region; (ii) it derives at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed, or has at least 50% of its assets located, within that country or region; (iii) it has the primary trading markets for its securities in that country or region; (iv) it has its principal place of business in or is otherwise headquartered in that country or region; or (v) it is a governmental entity or an agency, instrumentality or a political subdivision of that country or any country in that region; and (B) with respect to an instrument or issue, whether (i) its issuer is headquartered or organized in that country or region; (ii) it is issued to finance a project with significant assets or operations in that country or region; (iii) it is principally secured or backed by assets located in that country or region; (iv) it is a component of or its issuer is included in a recognized securities index for the country or region; or (v) it is denominated in the currency of an Asian country and addresses at least one of the other above criteria. The term “located” and the associated criteria listed above have been defined in such a way that Matthews has latitude in determining whether an issuer should be included within a region or country. The Fund may also invest in depositary receipts, including American, European, and Global Depositary Receipts.

The Fund seeks to provide a level of current income that is higher than the yield generally available in Asian equity markets over the long term. The Fund intends to distribute its realized income, if any, regularly (typically quarterly in March, June, September and December). There is no guarantee that the Fund will be able to distribute its realized income, if any, regularly. If the value of the Fund’s investments declines, the net asset value of the Fund will decline and investors may lose some or all of the value of their investments.

The Fund’s objective is total return with an emphasis on providing current income. Total return includes current income (dividends and distributions paid to shareholders) and capital gains (share price appreciation). The Fund measures total return over longer periods. Because of this objective, under normal market conditions, the Fund primarily invests in companies that exhibit attractive dividend yields and the propensity (in Matthews’ judgment) to pay increasing dividends. Matthews believes that in addition to providing current income, growing dividend payments by portfolio companies are an important component supporting capital appreciation. Matthews expects that such companies typically will be of medium or large size, but the Fund may invest in companies of any size. Matthews measures a company’s size with respect to fundamental criteria such as, but not limited to, market capitalization, book value, revenues, profits, cash flow, dividends paid and number of employees. The implementation of the principal investment strategies of the Fund may result in a significant portion of the Fund’s assets being invested from time to time in one or more sectors, but the Fund may invest in companies in any sector.

Therefore, credit risk may be greater for the Fund than for other funds that invest in higher-grade securities.

Consumer Discretionary Sector Risk: The success of consumer product manufacturers and retailers is tied closely to the performance of the overall local and international economy, interest rates, competition and consumer confidence. Success of companies in the consumer discretionary sector depends heavily on disposable household income and consumer spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer products and services in the marketplace.

Risks Associated with Medium-Size Companies: Medium-size companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss.

Risks Associated with Smaller Companies: Smaller companies may offer substantial opportunities for capital growth; they also involve substantial risks, and investments in smaller

If China were to exert its authority so as to alter the economic, political or legal structures or the existing social policy of Hong Kong, investor and business confidence in Hong Kong could be negatively affected and have an adverse effect on the Fund’s investments.

Risks Associated with Japan: The Japanese economy has only recently emerged from a prolonged economic downturn. Since the year 2000, Japan’s economic growth rate has remained relatively low. The Japanese economy is characterized by an aging demographic, declining population, large government debt and highly regulated labor market. Economic growth in Japan is dependent on domestic consumption, deregulation and consistent government policy. International trade, particularly with the U.S., also impacts growth of the Japanese economy, and adverse economic conditions in the U.S. or other trade partners may affect Japan.

Principal Investment Strategy

Under normal market conditions, the Matthews China Dividend Fund seeks to achieve its investment objective by investing at least 80% of its net assets, which include borrowings for investment purposes, in dividend-paying equity securities of companies located in China. The Fund may also invest in convertible debt and equity securities of any maturity and quality, including those that are unrated, or would be below investment grade if rated, of companies located in China. China also includes its administrative and other districts, such as Hong Kong. A company or other issuer is considered to be “located” in a country or a region, and a security or instrument is deemed to be an Asian (or specific country) security or instrument, if it has substantial ties to that country or region. Matthews currently makes that determination based primarily on one or more of the following criteria: (A) with respect to a company or issuer, whether (i) it is organized under the laws of that country or any country in that region; (ii) it derives at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed, or has at least 50% of its assets located, within that country or region; (iii) it has the primary trading markets for its securities in that country or region; (iv) it has its principal place of business in or is otherwise headquartered in that country or region; or (v) it is a governmental entity or an agency, instrumentality or a political subdivision of that country or any country in that region; and (B) with respect to an

instrument or issue, whether (i) its issuer is headquartered or organized in that country or region; (ii) it is issued to finance a project with significant assets or operations in that country or region; (iii) it is principally secured or backed by assets located in that country or region; (iv) it is a component of or its issuer is included in a recognized securities index for the country or region; or (v) it is denominated in the currency of an Asian country and addresses at least one of the other above criteria. The term “located” and the associated criteria listed above have been defined in such a way that Matthews has latitude in determining whether an issuer should be included within a region or country. The Fund may also invest in depositary receipts, including American, European and Global Depositary Receipts.

The Fund seeks to provide a level of current income that is higher than the yield generally available in Chinese equity markets over the long term. The Fund intends to distribute its realized income, if any, regularly (typically semi-annually in June and December). There is no guarantee that the Fund will be able to distribute its realized income, if any, regularly.

In addition, dividend-paying equity securities, in particular those whose market price is closely related to their yield, may exhibit greater sensitivity to interest rate changes. The Fund’s investment in such securities may also limit its potential for appreciation during a broad market advance.

Risks Associated with China, Hong Kong and Taiwan:

China: The Chinese government exercises significant control over China’s economy through its industrial policies (e.g., allocation of resources and other preferential treatment), monetary policy, management of currency exchange rates, and management of the payment of foreign currency-denominated obligations. Changes in these policies could adversely impact affected industries or companies in China. China’s economy, particularly its export-oriented industries, may be adversely impacted by trade or political disputes with China’s major trading partners, including the U.S. In addition, as its consumer class continues to grow, China’s domestically oriented industries may be especially sensitive to changes in government policy and investment cycles. China’s currency, which historically has been managed in a tight range relative to the U.S. dollar, may in the future be subject to greater uncertainty as Chinese authorities change the policies that determine the exchange rate mechanism.

Hong Kong: If China were to exert its authority so as to alter the economic, political or legal structures or the existing social policy of Hong Kong, investor and business confidence in Hong Kong could be negatively affected, which in turn could negatively affect markets and business performance and have an adverse effect on the Fund’s investments.

Taiwan: Although the relationship between China and Taiwan has been improving, there is the potential for future political or economic disturbances that may have an adverse impact on the values of investments in either China or Taiwan, or make investments in China and/or Taiwan impractical or impossible.

Depositary Receipts Risk: Although depositary receipts have risks similar to the securities that they represent, they may also involve higher expenses and may trade at a discount (or premium) to the underlying security. In addition, depositary receipts may not pass through voting and other shareholder rights, and may be less liquid than the underlying securities listed on an exchange.

Volatility Risk: The smaller size and lower levels of liquidity, as well as other factors, may result in changes in the prices of securities that are more volatile than those of companies in more developed regions. This volatility can cause the price of the Fund’s shares to go up or down dramatically. Because of this volatility, this Fund is better suited for long-term investors (typically five years or longer).

Convertible Securities Risk: The Fund may invest in convertible preferred stocks, and convertible bonds and debentures. The risks

of convertible bonds and debentures include repayment risk and interest rate risk. Many Asian convertible securities are not rated by rating agencies. The Fund may invest in convertible debt securities of any maturity and in those that are unrated, or would be below investment grade (referred to as “junk bonds”) if rated. Therefore, credit risk may be greater for the Fund than for other funds that invest in higher-grade securities.

Risks Associated with Smaller Companies: Smaller companies may offer substantial opportunities for capital growth; they also involve substantial risks, and investments in smaller companies may be considered speculative. Such companies often have limited product lines, markets or financial resources. Securities of smaller companies may trade less frequently and in lesser volume than more widely held securities and the securities of smaller companies generally are subject to more abrupt or erratic price movements than more widely held or larger, more established companies or the market indices in general.

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example of fund expenses, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 48% of the average value of its portfolio.

Asia consists of all countries and markets in Asia and includes developed, emerging, and frontier countries and markets in the Asian region. A company or other issuer is considered to be “located” in a country or a region, and a security or instrument is deemed to be an Asian (or specific country) security or instrument, if it has substantial ties to that country or region. Matthews currently makes that determination based primarily on one or more of the following criteria: (A) with respect to a company or issuer, whether (i) it is organized under the laws of that country or any country in that region; (ii) it derives at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed, or has at least 50% of its assets located, within that country or region; (iii) it has the primary trading markets for its securities in that country or region; (iv) it has its principal place of business in or is otherwise headquartered in that country or region; or (v) it is a governmental entity or an agency, instrumentality or a political subdivision of that country or any country in that region; and (B) with respect to an instrument or issue, whether (i) its issuer is headquartered or organized in that country or region; (ii) it is issued to finance a project with significant assets or operations in that country or region; (iii) it is principally secured or backed by assets located in that country or region; (iv) it is a component of or its issuer is included in a recognized securities index for the country or region; or (v) it is denominated in the currency of an Asian country and addresses at least one of the other above criteria. The term “located” and the associated criteria listed above have been defined in such a way that Matthews has latitude in determining whether an issuer should be included within a region or country. The Fund may also invest in depositary receipts, including American, European and Global Depositary Receipts.

Matthews is a fundamental investor and seeks to construct a diversified portfolio of securities of undervalued companies from the Asian region. The Fund seeks to invest in Asian companies that Matthews believes are high quality, undervalued with strong balance sheets, focused on their shareholders, and well-positioned to take advantage of Asia’s economic and financial evolution. The Fund attempts to offer investors a relatively stable means of participating in the economic prospects of the Asian region. The Fund may invest in companies of any size, including smaller size companies. Matthews measures a company’s size with respect to fundamental criteria such as, but not limited to, market capitalization, book value, revenues, profits, cash flow, dividends paid and number of employees. The implementation of the principal investment strategies of the Fund may result in a significant portion of the Fund’s assets being invested from time to time in one or more sectors, but the Fund may invest in companies in any sector.

Matthews’ value investment process focuses on a company’s intrinsic value. Matthews seeks out companies whose share price trades at a substantial discount to its estimate of the company’s intrinsic value. Intrinsic value includes both tangible and intangible, and quantitative and qualitative factors such as: a sound balance sheet, competitive market position, strong management, and favorable shareholder orientation. Investing in a company with a sound balance sheet (without excessive leverage) helps to reduce the risk of reliance on external sources of capital and gives management the ability to build value opportunistically. Matthews also seeks out

companies with a competitive position in their industry and region. Matthews seeks out companies with strong management that includes good corporate governance, a clear business strategy, integrity, and a demonstrated capacity for adaptability. Matthews also focuses on companies with a history of generating high incremental returns on capital. Matthews seeks companies whose management has built value for shareholders and has a good capital allocation track record.

Matthews seeks to create an investable universe of value companies that it believes trade at market values with discounts to their intrinsic value, have strong financial and market positions, have strong management and are oriented to creating value for their shareholders. Matthews assesses companies within this universe according to each of these factors. Generally, Matthews establishes larger positions in companies trading at a greater discount to Matthews’ estimate of their intrinsic value (taking into account other concerns such as diversification, risk management and liquidity). The Fund may sell positions as their market price approaches their intrinsic value, when more attractive alternatives are identified, or when Matthews believes that corporate governance issues may have developed.

Although Matthews generally believes that investors benefit in the long term when their assets are fully invested, Matthews also believes that some types of funds that employ a value investing approach, such as the Fund, may benefit from holding cash under certain market conditions (e.g., when Matthews considers equity markets to be overvalued) so that the Fund could deploy capital during market downturns. As a result, the Fund may, subject to other requirements and limitations, hold 15% or more of its net assets in cash or cash equivalent investments.

Principal Risks of Investment

There is no guarantee that your investment in the Fund will increase in value. The value of your investment in the Fund could go down, meaning you could lose money. The principal risks of investing in the Fund are:

Political, Social and Economic Risks of Investing in Asia: The value of the Fund’s assets may be adversely affected by political, economic, social and religious instability; inadequate investor protection; changes in laws or regulations of countries within the Asian region (including countries in which the Fund invests, as well as the broader region); international relations with other nations; natural disasters; corruption and military activity. The economies of many Asian countries differ from the economies of more developed countries in many respects, such as rate of growth, inflation, capital reinvestment, resource self-sufficiency, financial system stability, the national balance of payments position and sensitivity to changes in global trade.

Currency Risk: When the Fund conducts securities transactions in a foreign currency, there is the risk of the value of the foreign currency increasing or decreasing against the value of the U.S. dollar. The value of an investment denominated in a foreign currency will decline in U.S. dollar terms if that currency weakens against the U.S. dollar. While the Fund is permitted to hedge currency risks, Matthews does not anticipate doing so at this time. Additionally, Asian countries may utilize formal or informal currency-exchange controls or “capital controls.” Capital controls may impose restrictions on the

Fund’s ability to repatriate investments or income. Such controls may also affect the value of the Fund’s holdings.

Risks Associated with Emerging and Frontier Markets: Many Asian countries are considered emerging or frontier markets (newer or less developed emerging markets are also sometimes referred to as frontier markets). Such markets are often less stable politically and economically than developed markets such as the United States, and investing in these markets involves different and greater risks. There may be less publicly available information about companies in many Asian countries, and the stock exchanges and brokerage industries in many Asian countries typically do not have the level of government oversight as do those in the United States. Securities markets of many Asian countries are also substantially smaller, less liquid and more volatile than securities markets in the United States.

Value Stock Risk: Value stocks involve the risk that they may not reach their expected full market value for extended periods of time or may never reach such expected value, either because the market fails to recognize the stock’s intrinsic worth, or the expected value was misgauged. They also may decline in price even though they are already undervalued. Value stocks may go in and out of favor over time and may perform differently than the market as a whole.

Depositary Receipts Risk: Although depositary receipts have risks similar to the securities that they represent, they may also involve higher expenses and may trade at a discount (or premium) to the underlying security. In addition, depositary receipts may not pass through voting and other shareholder rights, and may be less liquid than the underlying securities listed on an exchange.

Volatility Risk: The smaller size and lower levels of liquidity in emerging markets, as well as other factors, may result in changes in the prices of Asian securities that are more volatile than those of companies in more developed regions. This volatility can cause the price of the Fund’s shares to go up or down dramatically. Because of this volatility, this Fund is better suited for long-term investors (typically five years or longer).

Convertible Securities Risk: The Fund may invest in convertible preferred stocks, and convertible bonds and debentures. The risks of convertible bonds and debentures include repayment risk and interest rate risk. Many Asian convertible securities are not rated by rating agencies. The Fund may invest in convertible securities of any maturity and in those that are unrated, or would be below investment grade (referred to as “junk bonds”) if rated. Therefore, credit risk may be greater for the Fund than for other funds that invest in higher-grade securities.

Risks Associated with Smaller Size Companies: Smaller companies may offer substantial opportunities for capital growth; they also involve substantial risks, and investments in smaller companies may be considered speculative. Such companies often have limited product lines, markets or financial resources. Securities of smaller companies may trade less frequently and in lesser volume than more widely held securities and the securities of smaller companies generally are subject to more abrupt or erratic price movements than more widely held or larger, more established companies or the market indices in general.

Cash Level Risk: This Fund may from time to time maintain 15% or more of its net assets in cash and cash equivalents, which may negatively impact the Fund’s ability to meet its investment objective and may cause the Fund to underperform other funds that do not maintain similar cash levels, especially in rising equity markets.

Risks Associated with China and Hong Kong: The Chinese government exercises significant control over China’s economy through its industrial policies, monetary policy, management of currency exchange rates, and management of the payment of foreign currency-denominated obligations. Changes in these policies could adversely impact affected industries or companies in China. China’s economy, particularly its export-oriented industries, may be adversely impacted by trade or political disputes with China’s major trading partners, including the U.S. In addition, as its consumer class continues to grow, China’s domestically oriented industries may be especially sensitive to changes in government policy and investment cycles. If China were to exert its authority so as to alter the economic, political or legal structures or the existing social policy of Hong Kong, investor and business confidence in Hong Kong could be negatively affected and have an adverse effect on the Fund’s investments.

Risks Associated with South Korea: Investing in South Korean securities has special risks, including the potential for increased militarization in North Korea. Securities trading on South Korean securities markets are concentrated in a relatively small number of issuers, which results in potentially fewer investment opportunities for the Fund. South Korea’s financial sector has shown certain signs of systemic weakness and illiquidity, which, if exacerbated, could prove to be a material risk for investments in South Korea. South Korea is dependent on foreign sources for its energy needs. A significant increase in energy prices could have an adverse impact on South Korea’s economy. The South Korean government has historically exercised and continues to exercise substantial influence over many aspects of the private sector.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of this Fund.

SHAREHOLDER FEES

(fees paid directly from your investment)

ANNUAL OPERATING EXPENSES

(expenses that you pay each year as a percentage of the value of your investment)

EXAMPLE OF FUND EXPENSES

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example of fund expenses, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 12% of the average value of its portfolio.

Principal Investment Strategy

Under normal market conditions, the Matthews Asia Growth Fund seeks to achieve its investment objective by investing at least 80% of its net assets, which include borrowings for investment purposes, in the common and preferred stocks of companies located in Asia. The Fund may also invest in convertible securities of any duration or quality, including those that are unrated, or would be below investment grade if rated, of Asian companies. Asia consists of all countries and markets in Asia, and includes developed, emerging, and frontier countries and markets in the Asian region. A company or other issuer is considered to be “located” in a country or a region, and a security or instrument is deemed to be an Asian (or specific country) security or instrument, if it has substantial ties to that country or region. Matthews currently makes that determination based primarily on one or more of the following criteria: (A) with respect to a company or issuer, whether (i) it is organized under the laws of that country or any country in that region; (ii) it derives at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed, or has at least 50% of its assets located, within that country or region; (iii) it has the primary trading markets for its securities in that country or region; (iv) it has its principal place of business in or is otherwise headquartered in that country or region; or (v) it is a governmental entity or an agency, instrumentality or a political subdivision of that country or any country in that region;

and (B) with respect to an instrument or issue, whether (i) its issuer is headquartered or organized in that country or region; (ii) it is issued to finance a project with significant assets or operations in that country or region; (iii) it is principally secured or backed by assets located in that country or region; (iv) it is a component of or its issuer is included in a recognized securities index for the country or region; or (v) it is denominated in the currency of an Asian country and addresses at least one of the other above criteria. The term “located” and the associated criteria listed above have been defined in such a way that Matthews has latitude in determining whether an issuer should be included within a region or country. The Fund may also invest in depositary receipts, including American, European, and Global Depositary Receipts.

The Fund seeks to invest in companies capable of sustainable growth based on the fundamental characteristics of those companies, including balance sheet information; number of employees; size and stability of cash flow; management’s depth, adaptability and integrity; product lines; marketing strategies; corporate governance; and financial health. Matthews expects that the companies in which the Fund invests typically will be of medium or large size, but the Fund may invest in companies of any size. Matthews measures a company’s size with respect to fundamental criteria such as, but not limited to, market capitalization, book value, revenues, profits, cash flow, dividends paid and number of employees. The implementation of the principal investment strategies of the Fund may result in a significant portion of the Fund’s assets being invested from time to time in one or more sectors, but the Fund may invest in companies in any sector.

Principal Risks of Investment

There is no guarantee that your investment in the Fund will increase in value. The value of your investment in the Fund could go down, meaning you could lose money. The principal risks of investing in the Fund are:

Political, Social and Economic Risks of Investing in Asia: The value of the Fund’s assets may be adversely affected by political, economic, social and religious instability; inadequate investor protection; changes in laws or regulations of countries within the Asian region (including countries in which the Fund invests, as well as the broader region); international relations with other nations; natural disasters; corruption and military activity. The economies of many Asian countries differ from the economies of more developed countries in many respects, such as rate of growth, inflation, capital reinvestment, resource self-sufficiency, financial system stability, the national balance of payments position and sensitivity to changes in global trade.

Currency Risk: When the Fund conducts securities transactions in a foreign currency, there is the risk of the value of the foreign currency increasing or decreasing against the value of the U.S. dollar. The value of an investment denominated in a foreign currency will decline in U.S. dollar terms if that currency weakens against the U.S. dollar. While the Fund is permitted to hedge currency risks, Matthews does not anticipate doing so at this time. Additionally, Asian countries may utilize formal or informal currency-exchange controls or “capital controls.” Capital controls may impose restrictions on the Fund’s ability to repatriate investments or income.

Such markets are often less stable politically and economically than developed markets such as the United States, and investing in these markets involves different and greater risks. There may be less publicly available information about companies in many Asian countries, and the stock exchanges and brokerage industries in many Asian countries typically do not have the level of government oversight as do those in the United States. Securities markets of many Asian countries are also substantially smaller, less liquid and more volatile than securities markets in the United States.

Growth Stock Risk: Growth stocks may be more volatile than other stocks because they are more sensitive to investor perceptions of the issuing company’s growth potential. Growth stocks may go in and out of favor over time and may perform differently than the market as a whole.

Depositary Receipts Risk: Although depositary receipts have risks similar to the securities that they represent, they may also involve higher expenses and may trade at a discount (or premium) to the underlying security. In addition, depositary receipts may not pass through voting and other shareholder rights, and may be less liquid than the underlying securities listed on an exchange.

Volatility Risk: The smaller size and lower levels of liquidity in emerging markets, as well as other factors, may result in changes in the prices of Asian securities that are more volatile than those of companies in more developed regions. This volatility can cause the price of the Fund’s shares to go up or down dramatically. Because of this volatility, this Fund is better suited for long-term investors (typically five years or longer).

Convertible Securities Risk: The Fund may invest in convertible preferred stocks, and convertible bonds and debentures. The risks of convertible bonds and debentures include repayment risk and interest rate risk. Many Asian convertible securities are not rated by rating agencies. The Fund may invest in convertible debt securities of any maturity and in those that are unrated, or would be below investment grade (referred to as “junk bonds”) if rated. Therefore, credit risk may be greater for the Fund than for other funds that invest in higher-grade securities.

Health Care Sector Risk: Companies in the health care sector may be affected by various factors, including extensive government regulations, heavy dependence on patent protection, pricing pressure, increased cost of medical products and services, and product liability claims. Health care companies may be thinly capitalized and may be susceptible to product obsolescence.

Risks Associated with Smaller Companies: Smaller companies may offer substantial opportunities for capital growth; they also involve substantial risks, and investments in smaller companies may be considered speculative. Such companies often have limited product lines, markets or financial resources. Securities of smaller companies may trade less frequently and in lesser volume than more widely held securities and the securities of smaller companies generally are subject to more abrupt or erratic price movements than more widely held or larger, more established companies or the market indices in general.

Risks Associated with Medium-Size Companies: Medium-size companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss.

Risks Associated with Japan: The Japanese economy has only recently emerged from a prolonged economic downturn. Since the year 2000, Japan’s economic growth rate has remained relatively low. The Japanese economy is characterized by an aging demographic, declining population, large government debt and highly regulated labor market. Economic growth in Japan is dependent on domestic consumption, deregulation and consistent government policy. International trade, particularly with the U.S., also impacts growth of the Japanese economy, and adverse economic conditions in the U.S. or other trade partners may affect Japan.

Risks Associated with China and Hong Kong: The Chinese government exercises significant control over China’s economy through its industrial policies, monetary policy, management of currency exchange rates, and management of the payment of foreign currency-denominated obligations. Changes in these policies could adversely impact affected industries or companies in China. China’s economy, particularly its export-oriented industries, may be adversely impacted by trade or political disputes with China’s major trading partners, including the U.S. In addition, as its consumer class continues to grow, China’s domestically oriented industries may be especially sensitive to changes in government policy and investment cycles. If China were to exert its authority so as to alter the economic, political or legal structures or the existing social policy of Hong Kong, investor and business confidence in Hong Kong could be negatively affected and have an adverse effect on the Fund’s investments.

Principal Investment Strategy

Under normal market conditions, the Matthews Pacific Tiger Fund seeks to achieve its investment objective by investing at least 80% of its net assets, which include borrowings for investment purposes, in the common and preferred stocks of companies located in Asia ex Japan, which consists of all countries and markets in Asia excluding Japan, but including all other developed, emerging, and frontier countries and markets in the Asian region. A company or other issuer is considered to be “located” in a country or a

region, and a security or instrument is deemed to be an Asian (or specific country) security or instrument, if it has substantial ties to that country or region. Matthews currently makes that determination based primarily on one or more of the following criteria: (A) with respect to a company or issuer, whether (i) it is organized under the laws of that country or any country in that region; (ii) it derives at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed, or has at least 50% of its assets located, within that country or region; (iii) it has the primary trading markets for its securities in that country or region; (iv) it has its principal place of business in or is otherwise headquartered in that country or region; or (v) it is a governmental entity or an agency, instrumentality or a political subdivision of that country or any country in that region; and (B) with respect to an instrument or issue, whether (i) its issuer is headquartered or organized in that country or region; (ii) it is issued to finance a project with significant assets or operations in that country or region; (iii) it is principally secured or backed by assets located in that country or region; (iv) it is a component of or its issuer is included in a recognized securities index for the country or region; or (v) it is denominated in the currency of an Asian country and addresses at least one of the other above criteria. The term “located” and the associated criteria listed above have been defined in such a way that Matthews has latitude in determining whether an issuer should be included within a region or country. The Fund may also invest in depositary receipts, including American, European and Global Depositary Receipts.

The Fund seeks to invest in companies capable of sustainable growth based on the fundamental characteristics of those companies, including balance sheet information; number of employees; size and stability of cash flow; management’s depth, adaptability and integrity; product lines; marketing strategies; corporate governance; and financial health. Matthews expects that the companies in which the Fund invests typically will be of medium or large size, but the Fund may invest in companies of any size. Matthews measures a company’s size with respect to fundamental criteria such as, but not limited to, market capitalization, book value, revenues, profits, cash flow, dividends paid and number of employees. The implementation of the principal investment strategies of the Fund may result in a significant portion of the Fund’s assets being invested from time to time in one or more sectors, but the Fund may invest in companies in any sector.

Principal Risks of Investment

There is no guarantee that your investment in the Fund will increase in value. The value of your investment in the Fund could go down, meaning you could lose money. The principal risks of investing in the Fund are:

Political, Social and Economic Risks of Investing in Asia: The value of the Fund’s assets may be adversely affected by political, economic, social and religious instability; inadequate investor protection; changes in laws or regulations of countries within the Asian region (including countries in which the Fund invests, as well as the broader region); international relations with other nations; natural disasters; corruption and military activity. The economies of many Asian countries differ from the economies of more developed countries in many respects, such as rate of growth, inflation, capital reinvestment, resource self-sufficiency, financial system stability, the national balance of payments position and sensitivity to changes in global trade.

Currency Risk: When the Fund conducts securities transactions in a foreign currency, there is the risk of the value of the foreign currency increasing or decreasing against the value of the U.S. dollar. The value of an investment denominated in a foreign currency will decline in U.S. dollar terms if that currency weakens against the U.S. dollar. While the Fund is permitted to hedge currency risks, Matthews does not anticipate doing so at this time. Additionally, Asian countries may utilize formal or informal currency-exchange controls or “capital controls.” Capital controls may impose restrictions on the Fund’s ability to repatriate investments or income. Such controls may also affect the value of the Fund’s holdings.

Risks Associated with Emerging and Frontier Markets: Many Asian countries are considered emerging or frontier markets (newer or less developed emerging markets are also sometimes referred to as frontier markets). Such markets are often less stable politically and economically than developed markets such as the United States, and investing in these markets involves different and greater risks. There may be less publicly available information about companies in many Asian countries, and the stock exchanges and brokerage industries in many Asian countries typically do not have the level of government oversight as do those in the United States. Securities markets of many Asian countries are also substantially smaller, less liquid and more volatile than securities markets in the United States.

Growth Stock Risk: Growth stocks may be more volatile than other stocks because they are more sensitive to investor perceptions of the issuing company’s growth potential. Growth stocks may go in and out of favor over time and may perform differently than the market as a whole.

Depositary Receipts Risk: Although depositary receipts have risks similar to the securities that they represent, they may also involve higher expenses and may trade at a discount (or premium) to the underlying security. In addition, depositary receipts may not pass through voting and other shareholder rights, and may be less liquid than the underlying securities listed on an exchange.

Volatility Risk: The smaller size and lower levels of liquidity in emerging markets, as well as other factors, may result in changes in the prices of Asian securities that are more volatile than those of companies in more developed regions. This volatility can cause the price of the Fund’s shares to go up or down dramatically. Because of this volatility, this Fund is better suited for long-term investors (typically five years or longer).

Financial Services Sector Risk: The Fund may invest a significant portion of its assets in the financial services sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. Financial services companies are subject to extensive government regulation and can be significantly affected by the availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, price competition and other sector-specific factors.

Consumer Staples Sector Risk: Companies in the consumer staples sector may be affected by various factors, including demographics and product trends, competitive pricing, consumer spending and demand, food fads, product contamination, marketing campaigns, environmental factors, government regulation, the performance of the overall economy, interest rates, and the cost of commodities.

Risks Associated with Medium-Size Companies: Medium-size companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss.

Risks Associated with China and Hong Kong: The Chinese government exercises significant control over China’s economy through its industrial policies, monetary policy, management of currency exchange rates, and management of the payment of foreign currency-denominated obligations. Changes in these policies could adversely impact affected industries or companies in China. China’s economy, particularly its export-oriented industries, may be adversely impacted by trade or political disputes with China’s major trading partners, including the U.S. In addition, as its consumer class continues to grow, China’s domestically oriented industries may be especially sensitive to changes in government policy and investment cycles. If China were to exert its authority so as to alter the economic, political or legal

structures or the existing social policy of Hong Kong, investor and business confidence in Hong Kong could be negatively affected and have an adverse effect on the Fund’s investments.

Risks Associated with India: Government actions, bureaucratic obstacles and inconsistent economic reform within the Indian government have had a significant effect on the Indian economy and could adversely affect market conditions, economic growth and the profitability of private enterprises in India. Global factors and foreign actions may inhibit the flow of foreign capital on which India is dependent to sustain its growth. Large portions of many Indian companies remain in the hands of their founders (including members of their families). Corporate governance standards of family-controlled companies may be weaker and less transparent, which increases the potential for loss and unequal treatment of investors. Religious, cultural and military disputes persist in India and between India and Pakistan (as well as sectarian groups within each country).

During the most recent fiscal year, the Fund’s portfolio turnover rate was 23% of the average value of its portfolio.

Principal Investment Strategy

Under normal market conditions, the Matthews Asia ESG Fund seeks to achieve its investment objective by investing at least 80% of its net assets, which include borrowings for investment purposes, in the common and preferred stocks of companies of any market capitalization located in Asia that Matthews believes satisfy one or more of its

environmental, social and governance (“ESG”) standards. The Fund may also invest in convertible securities and fixed-income securities, of any duration or quality, including high yield securities (also known as “junk bonds”), of Asian companies. Asia consists of all countries and markets in Asia and includes developed, emerging, and frontier countries and markets in the Asian region. A company or other issuer is considered to be “located” in a country or a region, and a security or instrument is deemed to be an Asian (or specific country) security or instrument, if it has substantial ties to that country or region. Matthews currently makes that determination based primarily on one or more of the following criteria: (A) with respect to a company or issuer, whether (i) it is organized under the laws of that country or any country in that region; (ii) it derives at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed, or has at least 50% of its assets located, within that country or region; (iii) it has the primary trading markets for its securities in that country or region; (iv) it has its principal place of business in or is otherwise headquartered in that country or region; or (v) it is a governmental entity or an agency, instrumentality or a political subdivision of that country or any country in that region; and (B) with respect to an instrument or issue, whether (i) its issuer is headquartered or organized in that country or region; (ii) it is issued to finance a project with significant assets or operations in that country or region; (iii) it is principally secured or backed by assets located in that country or region; (iv) it is a component of or its issuer is included in a recognized securities index for the country or region; or (v) it is denominated in the currency of an Asian country and addresses at least one of the other above criteria. The term “located” and the associated criteria listed above have been defined in such a way that Matthews has latitude in determining whether an issuer should be included within a region or country. The Fund may also invest in depositary receipts, including American, European, and Global Depositary Receipts.

The Fund’s primary focus is long-term capital appreciation. In achieving this objective, the Fund seeks to invest in companies that Matthews believes to be undervalued but of high quality and run by management teams with good operating and governance track records. While the Fund may invest in companies across the market capitalization spectrum, it has in the past invested, and may continue to invest, a substantial portion of Fund assets in smaller companies. In addition, the Fund seeks to invest in those Asian companies that have the potential to profit from the long-term opportunities presented by global environmental and social challenges as well as those Asian companies that proactively manage long-term risks presented by these challenges.

In addition to traditional financial data, the stock selection process takes into consideration ESG factors that the portfolio managers believe help identify companies with superior business models. There are no universally agreed upon objective standards for assessing ESG factors for companies. Rather, these factors tend to have many subjective characteristics, can be difficult to analyze, and frequently involve a balancing of a company’s business plans, objectives, actual conduct and other factors. ESG factors can vary over different periods and can evolve over time. They may also be difficult to apply consistently across regions, countries, industries or sectors. For these reasons, ESG standards may be aspirational and tend to be stated broadly and applied flexibly. In addition, investors

and others may disagree as to whether a certain company satisfies ESG standards given the absence of generally accepted criteria. In implementing its ESG strategy, the Fund evaluates potential investments primarily based on the following factors: sustainable environmental practices, responsible resource management and energy efficiency; policies regarding social responsibility, employee welfare, diversity and inclusion; and sound governance practices that align the interests of shareholders and management and emphasize a commitment to ESG integration. Businesses that meet one or more of the Fund’s ESG standards are generally businesses that currently engage in practices that have the effect of, or in the opinion of Matthews, have the potential of, making human or business activity less destructive to the environment, or businesses that promote positive social and economic developments. There can be no guarantee that a company that Matthews believes to meet one or more of the Fund’s ESG standards will actually conduct its affairs in a manner that is less destructive to the environment, or will actually promote positive social and economic developments. The Fund engages its portfolio companies on ESG matters primarily through active dialogue and proxy voting and by encouraging enhanced ESG disclosure. The implementation of the principal investment strategies of the Fund may result in a significant portion of the Fund’s assets being invested from time to time in one or more sectors, but the Fund may invest in companies in any sector.

Principal Risks of Investment

There is no guarantee that your investment in the Fund will increase in value. The value of your investment in the Fund could go down, meaning you could lose money. The principal risks of investing in the Fund are:

Political, Social and Economic Risks of Investing in Asia: The value of the Fund’s assets may be adversely affected by political, economic, social and religious instability; inadequate investor protection; changes in laws or regulations of countries within the Asian region (including countries in which the Fund invests, as well as the broader region); international relations with other nations; natural disasters; corruption and military activity. The economies of many Asian countries differ from the economies of more developed countries in many respects, such as rate of growth, inflation, capital reinvestment, resource self-sufficiency, financial system stability, the national balance of payments position and sensitivity to changes in global trade.

Currency Risk: When the Fund conducts securities transactions in a foreign currency, there is the risk of the value of the foreign currency increasing or decreasing against the value of the U.S. dollar. The value of an investment denominated in a foreign currency will decline in U.S. dollar terms if that currency weakens against the U.S. dollar. While the Fund is permitted to hedge currency risks, Matthews does not anticipate doing so at this time. Additionally, Asian countries may utilize formal or informal currency-exchange controls or “capital controls.” Capital controls may impose restrictions on the Fund’s ability to repatriate investments or income. Such controls may also affect the value of the Fund’s holdings.

Risks Associated with Emerging and Frontier Markets: Many Asian countries are considered emerging or frontier markets (newer or less developed emerging markets are also sometimes referred to as frontier markets). Such markets are often less stable politically and economically than developed markets such

as the United States, and investing in these markets involves different and greater risks. There may be less publicly available information about companies in many Asian countries, and the stock exchanges and brokerage industries in many Asian countries typically do not have the level of government oversight as do those in the United States. Securities markets of many Asian countries are also substantially smaller, less liquid and more volatile than securities markets in the United States.

Responsible Investing Risk: The Fund’s consideration of ESG factors in making its investment decisions may affect the Fund’s exposure to certain issuers, industries, sectors, regions or countries and may impact the Fund’s relative investment performance—positively or negatively—depending on whether such investments are in or out of favor in the market. Although an investment by the Fund in a company may satisfy one or more ESG standards in the view of the portfolio managers, there is no guarantee that such company actually promotes positive environmental, social or economic developments, and that same company may also fail to satisfy other ESG standards, in some cases even egregiously.

Growth Stock Risk: Growth stocks may be more volatile than other stocks because they are more sensitive to investor perceptions of the issuing company’s growth potential. Growth stocks may go in and out of favor over time and may perform differently than the market as a whole.

Depositary Receipts Risk: Although depositary receipts have risks similar to the securities that they represent, they may also involve higher expenses and may trade at a discount (or premium) to the underlying security. In addition, depositary receipts may not pass through voting and other shareholder rights, and may be less liquid than the underlying securities listed on an exchange.

Volatility Risk: The smaller size and lower levels of liquidity in emerging markets, as well as other factors, may result in changes in the prices of Asian securities that are more volatile than those of companies in more developed regions. This volatility can cause the price of the Fund’s shares to go up or down dramatically. Because of this volatility, this Fund is better suited for long-term investors (typically five years or longer).

Convertible Securities Risk: The Fund may invest in convertible preferred stocks, and convertible bonds and debentures. The risks of convertible bonds and debentures include repayment risk and interest rate risk. Many Asian convertible securities are not rated by rating agencies. The Fund may invest in convertible debt securities of any maturity and in those that are unrated, or would be below investment grade (referred to as “junk bonds”) if rated. Therefore, credit risk may be greater for the Fund than for other funds that invest in higher-grade securities.

Credit Risk: Credit risk refers to the risk that an issuer may default in the payment of principal and/or interest on an instrument.

Interest Rate Risk: Fixed-income securities may decline in value because of changes in interest rates. Bond prices generally rise when interest rates decline and generally decline when interest rates rise.

High Yield Securities Risk: High yield securities or unrated securities of similar credit quality (commonly known as “junk bonds”) are more likely to default than higher rated securities. These securities typically entail greater potential price volatility and are considered predominantly speculative. Issuers of high yield securities may also be more susceptible to adverse economic and competitive industry conditions than those of higher-rated securities.

Risks Associated with Smaller Companies: Smaller companies may offer substantial opportunities for capital growth; they also involve substantial risks, and investments in smaller companies may be considered speculative. Such companies often have limited product lines, markets or financial resources. Securities of smaller companies may trade less frequently and in lesser volume than more widely held securities and the securities of smaller companies generally are subject to more abrupt or erratic price movements than more widely held or larger, more established companies or the market indices in general.

Risks Associated with Medium-Size Companies: Medium-size companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss.

Risks Associated with China and Hong Kong: The Chinese government exercises significant control over China’s economy through its industrial policies, monetary policy, management of currency exchange rates, and management of the payment of foreign currency-denominated obligations. Changes in these policies could adversely impact affected industries or companies in China. China’s economy, particularly its export-oriented industries, may be adversely impacted by trade or political disputes with China’s major trading partners, including the U.S. In addition, as its consumer class continues to grow, China’s domestically oriented industries may be especially sensitive to changes in government policy and investment cycles. If China were to exert its authority so as to alter the economic, political or legal structures or the existing social policy of Hong Kong, investor and business confidence in Hong Kong could be negatively affected and have an adverse effect on the Fund’s investments.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of this Fund.

SHAREHOLDER FEES

(fees paid directly from your investment)

ANNUAL OPERATING EXPENSES

(expenses that you pay each year as a percentage of the value of your investment)

EXAMPLE OF FUND EXPENSES

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The example reflects the expense limitation for the one year period only. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example of fund expenses, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 26% of the average value of its portfolio.

Principal Investment Strategy

Under normal market conditions, the Matthews Emerging Asia Fund seeks to achieve its investment objective by investing at least 80% of its net assets, which include borrowings

for investment purposes, in the common and preferred stocks of companies located in Asia excluding Japan, South Korea, Hong Kong and Singapore. A company or other issuer is considered to be “located” in a country or a region, and a security or instrument is deemed to be an Asian (or specific country) security or instrument, if it has substantial ties to that country or region. Matthews currently makes that determination based primarily on one or more of the following criteria: (A) with respect to a company or issuer, whether (i) it is organized under the laws of that country or any country in that region; (ii) it derives at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed, or has at least 50% of its assets located, within that country or region; (iii) it has the primary trading markets for its securities in that country or region; (iv) it has its principal place of business in or is otherwise headquartered in that country or region; or (v) it is a governmental entity or an agency, instrumentality or a political subdivision of that country or any country in that region; and (B) with respect to an instrument or issue, whether (i) its issuer is headquartered or organized in that country or region; (ii) it is issued to finance a project with significant assets or operations in that country or region; (iii) it is principally secured or backed by assets located in that country or region; (iv) it is a component of or its issuer is included in a recognized securities index for the country or region; or (v) it is denominated in the currency of an Asian country and addresses at least one of the other above criteria. The term “located” and the associated criteria listed above have been defined in such a way that Matthews has latitude in determining whether an issuer should be included within a region or country. The Fund may also invest in convertible securities, of any duration or quality, including those that are unrated, or would be below investment grade if rated, of companies located in Asia excluding Japan, South Korea, Hong Kong and Singapore. The Fund may also invest in depositary receipts, including American, European and Global Depositary Receipts.

Under normal market conditions, the Fund invests a substantial portion of its net assets in the emerging countries and markets in the Asian region, including, but not limited to, Bangladesh, Cambodia, China (including Taiwan, but excluding Hong Kong), India, Indonesia, Laos, Malaysia, Mongolia, Myanmar, Pakistan, Papua New Guinea, Philippines, Sri Lanka, Thailand and Vietnam (“Emerging Asian Countries”). The list of Emerging Asian Countries may change from time to time. The Fund may invest in companies of any market capitalization, including micro-cap companies.

The Fund seeks to invest in companies capable of sustainable growth based on the fundamental characteristics of those companies, including balance sheet information; number of employees; size and stability of cash flow; management’s depth, adaptability and integrity; product lines; marketing strategies; corporate governance; and financial health. The implementation of the principal investment strategies of the Fund may result in a significant portion of the Fund’s assets being invested from time to time in one or more sectors, but the Fund may invest in companies in any sector.

Principal Risks of Investment

There is no guarantee that your investment in the Fund will increase in value. The value of your investment in the Fund could go down, meaning you could lose money. The principal risks of investing in the Fund are:

Political, Social and Economic Risks of Investing in Asia: The value of the Fund’s assets may be adversely affected by political, economic, social and religious instability; inadequate investor protection; changes in laws or regulations of countries within the Asian region (including countries in which the Fund invests, as well as the broader region); international relations with other nations; natural disasters; corruption and military activity. The economies of many Asian countries differ from the economies of more developed countries in many respects, such as rate of growth, inflation, capital reinvestment, resource self-sufficiency, financial system stability, the national balance of payments position and sensitivity to changes in global trade.

The value of an investment denominated in a foreign currency will decline in U.S. dollar terms if that currency weakens against the U.S. dollar.

Additionally, Asian countries may utilize formal or informal currency-exchange controls or “capital controls.” Capital controls may impose restrictions on the Fund’s ability to repatriate investments or income. Such controls may also affect the value of the Fund’s holdings.

Such markets are often less stable politically and economically than developed markets such as the United States, and investing in these markets involves different and greater risks. There may be less publicly available information about companies in many Asian countries, and the stock exchanges and brokerage industries in many Asian countries typically do not have the level of government oversight as do those in the United States. Securities markets of many Asian countries are also substantially smaller, less liquid and more volatile than securities markets in the United States.

Growth Stock Risk: Growth stocks may be more volatile than other stocks because they are more sensitive to investor perceptions of the issuing company’s growth potential. Growth stocks may go in and out of favor over time and may perform differently than the market as a whole.

Depositary Receipts Risk: Although depositary receipts have risks similar to the securities that they represent, they may also involve higher expenses and may trade at a discount (or premium) to the underlying security. In addition, depositary receipts may not pass through voting and other shareholder rights, and may be less liquid than the underlying securities listed on an exchange.

Volatility Risk: The smaller size and lower levels of liquidity in emerging markets, as well as other factors, may result in changes in the prices of Asian securities that are more volatile than those of companies in more developed regions. This volatility can cause the price of the Fund’s shares to go up or down dramatically. Because of this volatility, this Fund is better suited for long-term investors (typically five years or longer).

Convertible Securities Risk: The Fund may invest in convertible preferred stocks, and convertible bonds and debentures. The risks of convertible bonds and debentures include repayment risk and interest rate risk. Many Asian convertible securities are not rated by rating agencies. The Fund may invest in convertible debt securities of any maturity and in those that are unrated, or would be below investment grade (referred to as “junk bonds”) if rated. Therefore, credit risk may be greater for the Fund than for other funds that invest in higher-grade securities.

Consumer Staples Sector Risk: Companies in the consumer staples sector may be affected by various factors, including demographics and product trends, competitive pricing, consumer spending and demand, food fads, product contamination, marketing campaigns, environmental factors, government regulation, the performance of the overall economy, interest rates, and the cost of commodities.

Consumer Discretionary Sector Risk: The success of consumer product manufacturers and retailers is tied closely to the performance of the overall local and international economy, interest rates, competition and consumer confidence. Success of companies in the consumer discretionary sector depends heavily on disposable household income and consumer spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer products and services in the marketplace.

Risks Associated with Smaller Companies: Smaller companies may offer substantial opportunities for capital growth; they also involve substantial risks, and investments in smaller companies may be considered speculative. Such companies often have limited product lines, markets or financial resources. Securities of smaller companies may trade less frequently and in lesser volume than more widely held securities and the securities of smaller companies generally are subject to more abrupt or erratic price movements than more widely held or larger, more established companies or the market indices in general.

Risks Associated with Micro-Cap Companies: Investments in micro-cap companies are subject to the same types of risks described above for investments in smaller companies, but the likelihood of losses from such risks is even greater for micro-cap companies.

Risks Associated with Vietnam: Although Vietnam has experienced significant economic growth in the past three decades, Vietnam continues to face various challenges, including corruption, lack of transparency, uniformity and consistency in governmental regulations, heavy dependence on exports, a growing population, and increasing pollution. Vietnamese markets have relatively low levels of liquidity, which may result in extreme volatility in the prices of Vietnamese securities. Market volatility may also be heightened by the actions of a small number of investors.

Principal Investment Strategy

Under normal market conditions, the Matthews Asia Innovators Fund seeks to achieve its investment objective by investing at least 80% of its net assets, which include borrowings for investment purposes, in the common and preferred stocks of companies located in Asia that Matthews believes are innovators in their products, services, processes, business models, management, use of technology, or approach to creating, expanding or servicing their markets. Asia consists of all countries and markets in Asia, including developed, emerging, and frontier countries and markets in the Asian region. A company or other issuer is considered to be “located” in a country or a region, and a security or instrument is deemed to be an Asian (or specific country) security or instrument, if it has substantial ties to that country or region. Matthews currently makes that determination based primarily on one or more of the following criteria: (A) with respect to a company or issuer, whether (i) it is organized under the laws of that country or any country in that region; (ii) it derives at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed, or has at least 50% of its assets located, within that country or region; (iii) it has the primary trading markets for its securities in that country or region; (iv) it has its principal place of business in or is otherwise headquartered in that country or region; or (v) it is a governmental entity or an agency, instrumentality or a political subdivision of that country or any country in

that region; and (B) with respect to an instrument or issue, whether (i) its issuer is headquartered or organized in that country or region; (ii) it is issued to finance a project with significant assets or operations in that country or region; (iii) it is principally secured or backed by assets located in that country or region; (iv) it is a component of or its issuer is included in a recognized securities index for the country or region; or (v) it is denominated in the currency of an Asian country and addresses at least one of the other above criteria. The term “located” and the associated criteria listed above have been defined in such a way that Matthews has latitude in determining whether an issuer should be included within a region or country. The Fund may also invest in depositary receipts, including American, European and Global Depositary Receipts.

It is important to note that there are no universally agreed upon objective standards for assessing innovators. Innovative companies can be both old and new companies. Innovative companies can exist in any industries, old and new, and in any countries, emerging or developed. Companies perceived as innovators in one country or one industry might not be perceived as innovators in another country or another industry. For these reasons, the term innovators may be aspirational and tend to be stated broadly and applied flexibly.

The Fund seeks to invest in companies capable of sustainable growth based on the fundamental characteristics of those companies, including balance sheet information; number of employees; size and stability of cash flow; management’s depth, adaptability and integrity; product lines; marketing strategies; corporate governance; and financial health. The Fund may invest in companies of any size, including smaller size companies. Matthews measures a company’s size with respect to fundamental criteria such as, but not limited to, market capitalization, book value, revenues, profits, cash flow, dividends paid and number of employees. The implementation of the principal investment strategies of the Fund may result in a significant portion of the Fund’s assets being invested from time to time in one or more sectors, but the Fund may invest in companies in any sector.

The Fund has a fundamental policy to invest at least 25% of its net assets, which include borrowings for investment purposes, in the common and preferred stocks of companies that derive more than 50% of their revenues from the sale of products or services in science- and technology-related industries and services, which Matthews considers to be the following, among others: telecommunications, telecommunications equipment, computers, semiconductors, semiconductor capital equipment, networking, Internet and online service companies, media, office automation, server hardware producers, software companies (e.g., design, consumer and industrial), biotechnology and medical device technology companies, pharmaceuticals and companies involved in the distribution and servicing of these products.

Principal Risks of Investment

There is no guarantee that your investment in the Fund will increase in value. The value of your investment in the Fund could go down, meaning you could lose money. The principal risks of investing in the Fund are:

Political, Social and Economic Risks of Investing in Asia: The value of the Fund’s assets may be adversely affected by political, economic, social and religious instability; inadequate

investor protection; changes in laws or regulations of countries within the Asian region (including countries in which the Fund invests, as well as the broader region); international relations with other nations; natural disasters; corruption and military activity. The economies of many Asian countries differ from the economies of more developed countries in many respects, such as rate of growth, inflation, capital reinvestment, resource self-sufficiency, financial system stability, the national balance of payments position and sensitivity to changes in global trade.

Currency Risk: When the Fund conducts securities transactions in a foreign currency, there is the risk of the value of the foreign currency increasing or decreasing against the value of the U.S. dollar. The value of an investment denominated in a foreign currency will decline in U.S. dollar terms if that currency weakens against the U.S. dollar. While the Fund is permitted to hedge currency risks, Matthews does not anticipate doing so at this time. Additionally, Asian countries may utilize formal or informal currency-exchange controls or “capital controls.” Capital controls may impose restrictions on the Fund’s ability to repatriate investments or income. Such controls may also affect the value of the Fund’s holdings.

Risks Associated with Emerging and Frontier Markets: Many Asian countries are considered emerging or frontier markets (newer or less developed emerging markets are also sometimes referred to as frontier markets). Such markets are often less stable politically and economically than developed markets such as the United States, and investing in these markets involves different and greater risks. There may be less publicly available information about companies in many Asian countries, and the stock exchanges and brokerage industries in many Asian countries typically do not have the level of government oversight as do those in the United States. Securities markets of many Asian countries are also substantially smaller, less liquid and more volatile than securities markets in the United States.

Risks Associated with Investing in Innovative Companies: The standards for assessing innovative companies tend to have many subjective characteristics, can be difficult to analyze, and frequently involve a balancing of a company’s business plans, objectives, actual conduct and other factors. The definition of innovators can vary over different periods and can evolve over time. They may also be difficult to apply consistently across regions, countries, industries or sectors.

Growth Stock Risk: Growth stocks may be more volatile than other stocks because they are more sensitive to investor perceptions of the issuing company’s growth potential. Growth stocks may go in and out of favor over time and may perform differently than the market as a whole.

Science and Technology Companies Risk: As a fund that invests in science and technology companies, the Fund is subject to the risks associated with these industries. This makes the Fund more vulnerable to the price changes of securities issuers in science- and technology-related industries and to factors that affect these industries, relative to a broadly diversified fund. Certain science- and technology-related companies may face special risks because their products or services may not prove to be commercially successful. Many science and technology companies have limited operating histories and experience in managing adverse market conditions, and are also strongly affected by worldwide scientific

or technological developments and global demand cycles. As a result, their products may rapidly become obsolete, which could cause a dramatic decrease in the value of their stock. Such companies are also often subject to governmental regulation and may therefore be adversely affected by changes in governmental policies. The possible loss or impairment of intellectual property rights may also negatively impact science and technology companies.

Concentration Risk: By focusing on a group of industries, the Fund carries much greater risks of adverse developments and price movements in such industries than a fund that invests in a wider variety of industries. Because the Fund concentrates in a group of industries, there is also the risk that the Fund will perform poorly during a slump in demand for securities of companies in such industries.

Depositary Receipts Risk: Although depositary receipts have risks similar to the securities that they represent, they may also involve higher expenses and may trade at a discount (or premium) to the underlying security. In addition, depositary receipts may not pass through voting and other shareholder rights, and may be less liquid than the underlying securities listed on an exchange.

Volatility Risk: The smaller size and lower levels of liquidity in emerging markets, as well as other factors, may result in changes in the prices of Asian securities that are more volatile than those of companies in more developed regions. This volatility can cause the price of the Fund’s shares to go up or down dramatically. Because of this volatility, this Fund is better suited for long-term investors (typically five years or longer).

Financial Services Sector Risk: The Fund may invest a significant portion of its assets in the financial services sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. Financial services companies are subject to extensive government regulation and can be significantly affected by the availability and cost of

capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, price competition and other sector-specific factors.

Risks Associated with Smaller Companies: Smaller companies may offer substantial opportunities for capital growth; they also involve substantial risks, and investments in smaller companies may be considered speculative. Such companies often have limited product lines, markets or financial resources. Securities of smaller companies may trade less frequently and in lesser volume than more widely held securities and the securities of smaller companies generally are subject to more abrupt or erratic price movements than more widely held or larger, more established companies or the market indices in general.

Risks Associated with Medium-Size Companies: Medium-size companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss.

Risks Associated with China and Hong Kong: The Chinese government exercises significant control over China’s economy through its industrial policies, monetary policy, management of currency exchange rates, and management of the payment of foreign currency-denominated obligations. Changes in these policies could adversely impact affected industries or companies in China. China’s economy, particularly its export-oriented industries, may be adversely impacted by trade or political disputes with China’s major trading partners, including the U.S. In addition, as its consumer class continues to grow, China’s domestically oriented industries may be especially sensitive to changes in government policy and investment cycles. If China were to exert its authority so as to alter the economic, political or legal structures or the existing social policy of Hong Kong, investor and business confidence in Hong Kong could be negatively affected and have an adverse effect on the Fund’s investments.

Principal Investment Strategy

Under normal market conditions, the Matthews China Fund seeks to achieve its investment objective by investing at least 80% of its net assets, which include borrowings for investment purposes, in the common and preferred stocks of companies located in China. China includes its administrative and other districts, such as Hong Kong. A company or other issuer is considered to be “located” in a country or a region, and a security or instrument is deemed to be an Asian (or specific country) security or instrument, if it has substantial ties to that country or region. Matthews currently makes that determination based primarily on one or more of the following criteria: (A) with respect to a company or issuer, whether (i) it is organized under the laws of that country or any country in that region; (ii) it derives at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed, or has at least 50% of its assets located, within that country or region; (iii) it has the primary trading markets for its securities in that country or region; (iv) it has its principal place of business in or is otherwise headquartered in that country or region; or (v) it is a governmental entity or an agency, instrumentality or a political subdivision of that country or any country in that region; and (B) with respect to an instrument or issue, whether (i) its issuer is headquartered or organized in that country or region; (ii) it is issued to finance a project with significant assets or operations in that country or region; (iii) it is principally secured or

backed by assets located in that country or region; (iv) it is a component of or its issuer is included in a recognized securities index for the country or region; or (v) it is denominated in the currency of an Asian country and addresses at least one of the other above criteria. The term “located” and the associated criteria listed above have been defined in such a way that Matthews has latitude in determining whether an issuer should be included within a region or country. The Fund may also invest in depositary receipts, including American, European and Global Depositary Receipts.

The Fund seeks to invest in companies capable of sustainable growth based on the fundamental characteristics of those companies, including balance sheet information; number of employees; size and stability of cash flow; management’s depth, adaptability and integrity; product lines; marketing strategies; corporate governance; and financial health. Matthews expects that the companies in which the Fund invests typically will be of medium or large size, but the Fund may invest in companies of any size. Matthews measures a company’s size with respect to fundamental criteria such as, but not limited to, market capitalization, book value, revenues, profits, cash flow, dividends paid and number of employees. The implementation of the principal investment strategies of the Fund may result in a significant portion of the Fund’s assets being invested from time to time in one or more sectors, but the Fund may invest in companies in any sector.

Principal Risks of Investment

There is no guarantee that your investment in the Fund will increase in value. The value of your investment in the Fund could go down, meaning you could lose money. The principal risks of investing in the Fund are:

Political, Social and Economic Risks of Investing in Asia: The value of the Fund’s assets may be adversely affected by political, economic, social and religious instability; inadequate investor protection; changes in laws or regulations of countries within the Asian region (including countries in which the Fund invests, as well as the broader region); international relations with other nations; natural disasters; corruption and military activity. The economies of many Asian countries differ from the economies of more developed countries in many respects, such as rate of growth, inflation, capital reinvestment, resource self-sufficiency, financial system stability, the national balance of payments position and sensitivity to changes in global trade.

Currency Risk: When the Fund conducts securities transactions in a foreign currency, there is the risk of the value of the foreign currency increasing or decreasing against the value of the U.S. dollar. The value of an investment denominated in a foreign currency will decline in U.S. dollar terms if that currency weakens against the U.S. dollar. While the Fund is permitted to hedge currency risks, Matthews does not anticipate doing so at this time. Additionally, China may utilize formal or informal currency-exchange controls or “capital controls.” Capital controls may impose restrictions on the Fund’s ability to repatriate investments or income. Such controls may also affect the value of the Fund’s holdings.

Risks Associated with Emerging and Frontier Markets: Many Asian countries are considered emerging or frontier markets (newer or less developed emerging markets are also sometimes referred to as frontier markets). Such markets are

often less stable politically and economically than developed markets such as the United States, and investing in these markets involves different and greater risks. There may be less publicly available information about companies in many Asian countries, and the stock exchanges and brokerage industries in many Asian countries typically do not have the level of government oversight as do those in the United States. Securities markets of many Asian countries are also substantially smaller, less liquid and more volatile than securities markets in the United States.

Risks Associated with China, Hong Kong and Taiwan:

China: The Chinese government exercises significant control over China’s economy through its industrial policies (e.g., allocation of resources and other preferential treatment), monetary policy, management of currency exchange rates, and management of the payment of foreign currency- denominated obligations. Changes in these policies could adversely impact affected industries or companies in China. China’s economy, particularly its export-oriented industries, may be adversely impacted by trade or political disputes with China’s major trading partners, including the U.S. In addition, as its consumer class continues to grow, China’s domestically oriented industries may be especially sensitive to changes in government policy and investment cycles. China’s currency, which historically has been managed in a tight range relative to the U.S. dollar, may in the future be subject to greater uncertainty as Chinese authorities change the policies that determine the exchange rate mechanism.

Hong Kong: If China were to exert its authority so as to alter the economic, political or legal structures or the existing social policy of Hong Kong, investor and business confidence in Hong Kong could be negatively affected, which in turn could negatively affect markets and business performance and have an adverse effect on the Fund’s investments.

Taiwan: Although the relationship between China and Taiwan has been improving, there is the potential for future political or economic disturbances that may have an adverse impact on the values of investments in either China or Taiwan, or make investments in China and/or Taiwan impractical or impossible.

Growth Stock Risk: Growth stocks may be more volatile than other stocks because they are more sensitive to investor perceptions of the issuing company’s growth potential. Growth stocks may go in and out of favor over time and may perform differently than the market as a whole.

Depositary Receipts Risk: Although depositary receipts have risks similar to the securities that they represent, they may also involve higher expenses and may trade at a discount (or premium) to the underlying security. In addition, depositary receipts may not pass through voting and other shareholder rights, and may be less liquid than the underlying securities listed on an exchange.

Volatility Risk: The smaller size and lower levels of liquidity in emerging markets, as well as other factors, may result in changes in the prices of Asian securities that are more volatile than those of companies in more developed regions. This volatility can cause the price of the Fund’s shares to go up or down dramatically. Because of this volatility, this Fund is better suited for long-term investors (typically five years or longer).

Financial Services Sector Risk: The Fund may invest a significant portion of its assets in the financial services sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. Financial services companies are subject to extensive government regulation and can be significantly affected by the availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, price competition and other sector-specific factors.

Information Technology Sector Risk: Information technology companies may be significantly affected by aggressive pricing as a result of intense competition and by rapid product

obsolescence due to rapid development of technological innovations and frequent new product introduction. Other factors, such as short product cycle, possible loss or impairment of intellectual property rights, and changes in government regulations, may also adversely impact information technology companies.

Risks Associated with Medium-Size Companies: Medium-size companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss.

ANNUAL OPERATING EXPENSES

(expenses that you pay each year as a percentage of the value of your investment)

EXAMPLE OF FUND EXPENSES

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example of fund expenses, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 21% of the average value of its portfolio.

Principal Investment Strategy

Under normal market conditions, the Matthews India Fund seeks to achieve its investment objective by investing at least 80% of its net assets, which include borrowings for investment purposes, in publicly traded common stocks, preferred stocks and convertible securities of companies located in India. A company or other issuer is considered to be “located” in a country or a region, and a security or instrument is deemed to be an Asian (or specific country) security or instrument, if it has substantial ties to that country or region. Matthews currently makes that determination based primarily on one or more of the following criteria: (A) with respect to a company or issuer, whether (i) it is organized under the laws of that country or any country in that region; (ii) it derives at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed, or has at least 50% of its assets located, within that country or region; (iii) it has the primary trading markets for its securities in that country or region; (iv) it has its principal place of business in or is otherwise headquartered in that country or region; or (v) it is a governmental entity or an agency, instrumentality or a political subdivision of that country or any country in that region; and (B) with respect to an instrument or issue, whether (i) its issuer is headquartered or organized in that country or region; (ii) it is issued to finance a project with significant assets or operations in that country or region; (iii) it is principally secured or backed by assets located

in that country or region; (iv) it is a component of or its issuer is included in a recognized securities index for the country or region; or (v) it is denominated in the currency of an Asian country and addresses at least one of the other above criteria. The term “located” and the associated criteria listed above have been defined in such a way that Matthews has latitude in determining whether an issuer should be included within a region or country. The Fund may also invest in depositary receipts, including American, European and Global Depositary Receipts.

The Fund seeks to invest in companies capable of sustainable growth based on the fundamental characteristics of those companies, including balance sheet information; number of employees; size and stability of cash flow; management’s depth, adaptability and integrity; product lines; marketing strategies; corporate governance; and financial health. While the Fund may invest in companies across the market capitalization spectrum, it has in the past invested, and may continue to invest, a substantial portion of Fund assets in smaller companies. Matthews measures a company’s size with respect to fundamental criteria such as, but not limited to, market capitalization, book value, revenues, profits, cash flow, dividends paid and number of employees. The implementation of the principal investment strategies of the Fund may result in a significant portion of the Fund’s assets being invested from time to time in one or more sectors, but the Fund may invest in companies in any sector.

Principal Risks of Investment

There is no guarantee that your investment in the Fund will increase in value. The value of your investment in the Fund could go down, meaning you could lose money. The principal risks of investing in the Fund are:

Political, Social and Economic Risks of Investing in Asia: The value of the Fund’s assets may be adversely affected by political, economic, social and religious instability; inadequate investor protection; changes in laws or regulations of countries within the Asian region (including countries in which the Fund invests, as well as the broader region); international relations with other nations; natural disasters; corruption and military activity. The economies of many Asian countries differ from the economies of more developed countries in many respects, such as rate of growth, inflation, capital reinvestment, resource self-sufficiency, financial system stability, the national balance of payments position and sensitivity to changes in global trade.

Currency Risk: When the Fund conducts securities transactions in a foreign currency, there is the risk of the value of the foreign currency increasing or decreasing against the value of the U.S. dollar. The value of an investment denominated in a foreign currency will decline in U.S. dollar terms if that currency weakens against the U.S. dollar. While the Fund is permitted to hedge currency risks, Matthews does not anticipate doing so at this time. Additionally, India may utilize formal or informal currency-exchange controls or “capital controls.” Capital controls may impose restrictions on the Fund’s ability to repatriate investments or income. Such controls may also affect the value of the Fund’s holdings.

Risks Associated with Emerging and Frontier Markets: Many Asian countries are considered emerging or frontier markets (newer or less developed emerging markets are also sometimes

referred to as frontier markets). Such markets are often less stable politically and economically than developed markets such as the United States, and investing in these markets involves different and greater risks. There may be less publicly available information about companies in many Asian countries, and the stock exchanges and brokerage industries in many Asian countries typically do not have the level of government oversight as do those in the United States. Securities markets of many Asian countries are also substantially smaller, less liquid and more volatile than securities markets in the United States.

Risks Associated with India: Government actions, bureaucratic obstacles and inconsistent economic reform within the Indian government have had a significant effect on the Indian economy and could adversely affect market conditions, economic growth and the profitability of private enterprises in India. Global factors and foreign actions may inhibit the flow of foreign capital on which India is dependent to sustain its growth. Large portions of many Indian companies remain in the hands of their founders (including members of their families). Corporate governance standards of family-controlled companies may be weaker and less transparent, which increases the potential for loss and unequal treatment of investors. India experiences many of the risks associated with developing economies, including relatively low levels of liquidity, which may result in extreme volatility in the prices of Indian securities.

Religious, cultural and military disputes persist in India and between India and Pakistan (as well as sectarian groups within each country). Both India and Pakistan have tested nuclear arms, and the threat of deployment of such weapons could hinder development of the Indian economy, and escalating tensions could impact the broader region, including China.

Growth Stock Risk: Growth stocks may be more volatile than other stocks because they are more sensitive to investor perceptions of the issuing company’s growth potential. Growth stocks may go in and out of favor over time and may perform differently than the market as a whole.

Depositary Receipts Risk: Although depositary receipts have risks similar to the securities that they represent, they may also involve higher expenses and may trade at a discount (or premium) to the underlying security. In addition, depositary receipts may not pass through voting and other shareholder rights, and may be less liquid than the underlying securities listed on an exchange.

Volatility Risk: The smaller size and lower levels of liquidity in emerging markets, as well as other factors, may result in changes in the prices of Asian securities that are more volatile than those of companies in more developed regions. This volatility can cause the price of the Fund’s shares to go up or down dramatically. Because of this volatility, this Fund is better suited for long-term investors (typically five years or longer).

Convertible Securities Risk: The Fund may invest in convertible preferred stocks, and convertible bonds and debentures. The risks of convertible bonds and debentures include repayment risk and interest rate risk. Many Asian convertible securities are not rated by rating agencies. The Fund may invest in convertible debt securities of any maturity and in those that are unrated, or would be below investment

grade (referred to as “junk bonds”) if rated. Therefore, credit risk may be greater for the Fund than for other funds that invest in higher-grade securities.

Financial Services Sector Risk: The Fund may invest a significant portion of its assets in the financial services sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. Financial services companies are subject to extensive government regulation and can be significantly affected by the availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, price competition and other sector-specific factors.

Risks Associated with Smaller Companies: Smaller companies may offer substantial opportunities for capital growth; they also involve substantial risks, and investments in smaller

companies may be considered speculative. Such companies often have limited product lines, markets or financial resources. Securities of smaller companies may trade less frequently and in lesser volume than more widely held securities and the securities of smaller companies generally are subject to more abrupt or erratic price movements than more widely held or larger, more established companies or the market indices in general.

Risks Associated with Medium-Size Companies: Medium-size companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss.

Principal Investment Strategy

Under normal market conditions, the Matthews Japan Fund seeks to achieve its investment objective by investing at least 80% of its net assets, which include borrowings for investment purposes, in the common and preferred stocks of companies located in Japan. A company or other issuer is considered to be “located” in a country or a region, and a security or instrument is deemed to be an Asian (or specific country) security or instrument, if it has substantial ties to that country or region. Matthews currently makes that determination based primarily on one or more of the following criteria: (A) with respect to a company or issuer, whether (i) it is organized under the laws of that country or any country in that region; (ii) it derives at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed, or has at least 50% of its assets located, within that country or region; (iii) it has the primary trading markets for its securities in that country or region; (iv) it has its principal place of business in or is otherwise headquartered in that country or region; or (v) it is a governmental entity or an agency, instrumentality or a political subdivision of that country or any country in that region; and (B) with respect to an instrument or issue, whether (i) its issuer is headquartered or organized in that country or region; (ii) it is issued to finance a project with significant assets or operations in that country or region; (iii) it is principally secured or backed by assets located in that country or region; (iv) it is a component of or

its issuer is included in a recognized securities index for the country or region; or (v) it is denominated in the currency of an Asian country and addresses at least one of the other above criteria. The term “located” and the associated criteria listed above have been defined in such a way that Matthews has latitude in determining whether an issuer should be included within a region or country. The Fund may also invest in depositary receipts, including American, European and Global Depositary Receipts.

The Fund seeks to invest in companies capable of sustainable growth based on the fundamental characteristics of those companies, including balance sheet information; number of employees; size and stability of cash flow; management’s depth, adaptability and integrity; product lines; marketing strategies; corporate governance; and financial health. The Fund may invest in companies of any market capitalization. Matthews measures a company’s size with respect to fundamental criteria such as, but not limited to, market capitalization, book value, revenues, profits, cash flow, dividends paid and number of employees. The implementation of the principal investment strategies of the Fund may result in a significant portion of the Fund’s assets being invested from time to time in one or more sectors, but the Fund may invest in companies in any sector.

Principal Risks of Investment

There is no guarantee that your investment in the Fund will increase in value. The value of your investment in the Fund could go down, meaning you could lose money. The principal risks of investing in the Fund are:

Political, Social and Economic Risks of Investing in Asia: The value of the Fund’s assets may be adversely affected by political, economic, social and religious instability; inadequate investor protection; changes in laws or regulations of countries within the Asian region (including countries in which the Fund invests, as well as the broader region); international relations with other nations; natural disasters; corruption and military activity. The economies of many Asian countries differ from the economies of more developed countries in many respects, such as rate of growth, inflation, capital reinvestment, resource self-sufficiency, financial system stability, the national balance of payments position and sensitivity to changes in global trade.

Currency Risk: When the Fund conducts securities transactions in a foreign currency, there is the risk of the value of the foreign currency increasing or decreasing against the value of the U.S. dollar. The value of an investment denominated in a foreign currency will decline in U.S. dollar terms if that currency weakens against the U.S. dollar. While the Fund is permitted to hedge currency risks, Matthews does not anticipate doing so at this time.

Risks Associated with Japan: The Japanese economy has only recently emerged from a prolonged economic downturn. Since

the year 2000, Japan’s economic growth rate has remained relatively low. The Japanese economy is characterized by an aging demographic, declining population, large government debt and highly regulated labor market. Economic growth in Japan is dependent on domestic consumption, deregulation and consistent government policy. International trade, particularly with the U.S., also impacts growth of the Japanese economy, and adverse economic conditions in the U.S. or other trade partners may affect Japan. Japan also has a growing economic relationship with China and other Southeast Asian countries, and thus Japan’s economy may also be affected by economic, political or social instability in those countries (whether resulting from local or global events). Other factors, such as the occurrence of natural disasters and relations with neighboring countries (including China, South Korea, North Korea and Russia), may also negatively impact the Japanese economy.

Growth Stock Risk: Growth stocks may be more volatile than other stocks because they are more sensitive to investor perceptions of the issuing company’s growth potential. Growth stocks may go in and out of favor over time and may perform differently than the market as a whole.

Depositary Receipts Risk: Although depositary receipts have risks similar to the securities that they represent, they may also involve higher expenses and may trade at a discount (or premium) to the underlying security. In addition, depositary receipts may not pass through voting and other shareholder rights, and may be less liquid than the underlying securities listed on an exchange.

Industrial Sector Risk: Industrial companies are affected by supply and demand both for their specific product or service and for industrial sector products in general. Government regulation, world events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these companies.

Risks Associated with Medium-Size Companies: Medium-size companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss.

Risks Associated with Smaller Companies: Smaller companies may offer substantial opportunities for capital growth; they also involve substantial risks, and investments in smaller companies may be considered speculative. Such companies often have limited product lines, markets or financial resources. Securities of smaller companies may trade less frequently and in lesser volume than more widely held securities and the securities of smaller companies generally are subject to more abrupt or erratic price movements than more widely held or larger, more established companies or the market indices in general.

Additionally, South Korea may utilize formal or informal currency-exchange controls or “capital controls.” Capital controls may impose restrictions on the Fund’s ability to repatriate investments or income. Such controls may also affect the value of the Fund’s holdings.

Risks Associated with Emerging and Frontier Markets: Many Asian countries are considered emerging or frontier markets (newer or less developed emerging markets are also sometimes referred to as frontier markets). Such markets are often less stable politically and economically than developed markets

such as the United States, and investing in these markets involves different and greater risks. There may be less publicly available information about companies in many Asian countries, and the stock exchanges and brokerage industries in many Asian countries typically do not have the level of government oversight as do those in the United States. Securities markets of many Asian countries are also substantially smaller, less liquid and more volatile than securities markets in the United States.

Information Technology Sector Risk: Information technology companies may be significantly affected by aggressive pricing as a result of intense competition and by rapid product obsolescence due to rapid development of technological innovations and frequent new product introduction. Other factors, such as short product cycle, possible loss or impairment of intellectual property rights, and changes in government regulations, may also adversely impact information technology companies.

Risks Associated with South Korea: Investing in South Korean securities has special risks, including those related to political, economic and social instability in South Korea and the potential for increased militarization in North Korea. Securities trading on South Korean securities markets are concentrated in a relatively small number of issuers, which results in potentially fewer investment opportunities for the Fund. South Korea’s financial sector has shown certain signs of systemic weakness and illiquidity, which, if exacerbated, could prove to be a material risk for investments in South Korea. South Korea is dependent on foreign sources for its energy needs. A significant increase in energy prices could have an adverse impact on South Korea’s economy. The South Korean government has historically exercised and continues to exercise substantial influence over many aspects of the private sector. The South Korean government from time to time has informally influenced the prices of certain products, encouraged companies to invest or to concentrate in particular industries and induced mergers between companies in industries experiencing excess capacity.

Growth Stock Risk: Growth stocks may be more volatile than other stocks because they are more sensitive to investor perceptions of the issuing company’s growth potential. Growth stocks may go in and out of favor over time and may perform differently than the market as a whole.

Depositary Receipts Risk: Although depositary receipts have risks similar to the securities that they represent, they may also involve higher expenses and may trade at a discount (or premium) to the underlying security. In addition, depositary receipts may not pass through voting and other shareholder rights, and may be less liquid than the underlying securities listed on an exchange.

This volatility can cause the price of the Fund’s shares to go up or down dramatically. Because of this volatility, this Fund is better suited for long-term investors (typically five years or longer).

Principal Investment Strategy

Under normal market conditions, the Matthews Asia Small Companies Fund seeks to achieve its investment objective by investing at least 80% of its net assets, which

include borrowings for investment purposes, in the common and preferred stocks of Small Companies (defined below) located in Asia ex Japan, which consists of all countries and markets in Asia excluding Japan, but including all other developed, emerging, and frontier countries and markets in the Asian region. A company or other issuer is considered to be “located” in a country or a region, and a security or instrument is deemed to be an Asian (or specific country) security or instrument, if it has substantial ties to that country or region. Matthews currently makes that determination based primarily on one or more of the following criteria: (A) with respect to a company or issuer, whether (i) it is organized under the laws of that country or any country in that region; (ii) it derives at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed, or has at least 50% of its assets located, within that country or region; (iii) it has the primary trading markets for its securities in that country or region; (iv) it has its principal place of business in or is otherwise headquartered in that country or region; or (v) it is a governmental entity or an agency, instrumentality or a political subdivision of that country or any country in that region; and (B) with respect to an instrument or issue, whether (i) its issuer is headquartered or organized in that country or region; (ii) it is issued to finance a project with significant assets or operations in that country or region; (iii) it is principally secured or backed by assets located in that country or region; (iv) it is a component of or its issuer is included in a recognized securities index for the country or region; or (v) it is denominated in the currency of an Asian country and addresses at least one of the other above criteria. The term “located” and the associated criteria listed above have been defined in such a way that Matthews has latitude in determining whether an issuer should be included within a region or country. The Fund may also invest in depositary receipts, including American, European and Global Depositary Receipts.

The Fund seeks to invest in smaller companies capable of sustainable growth based on the fundamental characteristics of those companies, including balance sheet information; number of employees; size and stability of cash flow; management’s depth, adaptability and integrity; product lines; marketing strategies; corporate governance; and financial health. Matthews determines whether a company should be considered to be a small company based on the size of its revenues, number of employees, net assets, the size and depth of its product line, level of development, and other factors compared to other companies in its industry, sector or region (“Small Companies”). The Fund may not invest in any company that has a market capitalization (the number of the company’s shares outstanding times the market price per share for such securities) higher than the greater of $3 billion or the market capitalization of the largest company included in the Fund’s primary benchmark index, if, at the time of purchase, more than 20% of the Fund’s assets are invested in such companies. The largest company in the Fund’s primary benchmark, the MSCI All Country Asia ex Japan Small Cap Index, had a market capitalization of $4.42 billion on December 31, 2018. Companies in which the Fund invests typically operate in growth industries and possess the potential to expand their scope of business over time. The Fund may continue to hold a security if its market capitalization increases above these levels after purchase. The implementation of the principal investment strategies of the Fund may result in a significant portion of the Fund’s assets being invested from time to time in one or more sectors, but the Fund may invest in companies in any sector.

There is no guarantee that your investment in the Fund will increase in value. The value of your investment in the Fund could go down, meaning you could lose money. The principal risks of investing in the Fund are:

Political, Social and Economic Risks of Investing in Asia: The value of the Fund’s assets may be adversely affected by political, economic, social and religious instability; inadequate investor protection; changes in laws or regulations of countries within the Asian region (including countries in which the Fund invests, as well as the broader region); international relations with other nations; natural disasters; corruption and military activity. The economies of many Asian countries differ from the economies of more developed countries in many respects, such as rate of growth, inflation, capital reinvestment, resource self-sufficiency, financial system stability, the national balance of payments position and sensitivity to changes in global trade.

Currency Risk: When the Fund conducts securities transactions in a foreign currency, there is the risk of the value of the foreign currency increasing or decreasing against the value of the U.S. dollar. The value of an investment denominated in a foreign currency will decline in U.S. dollar terms if that currency weakens against the U.S. dollar. While the Fund is permitted to hedge currency risks, Matthews does not anticipate doing so at this time. Additionally, Asian countries may utilize formal or informal currency-exchange controls or “capital controls.” Capital controls may impose restrictions on the Fund’s ability to repatriate investments or income. Such controls may also affect the value of the Fund’s holdings.

Risks Associated with Emerging and Frontier Markets: Many Asian countries are considered emerging or frontier markets (newer or less developed emerging markets are also sometimes referred to as frontier markets). Such markets are often less stable politically and economically than developed markets such as the United States, and investing in these markets involves different and greater risks. There may be less publicly available information about companies in many Asian countries, and the stock exchanges and brokerage industries in many Asian countries typically do not have the level of government oversight as do those in the United States. Securities markets of many Asian countries are also substantially smaller, less liquid and more volatile than securities markets in the United States.

Risks Associated with Smaller Companies: Smaller companies may offer substantial opportunities for capital growth; they also involve substantial risks, and investments in smaller companies may be considered speculative. Such companies often have limited product lines, markets or financial resources. Smaller companies may be more dependent on one or few key persons and may lack depth of management. Larger portions of their stock may be held by a small number of investors (including founders and management) than is typical of larger companies. Credit may be more difficult to obtain(and on less advantageous terms) than for larger companies. As a result, the influence of creditors (and the impact of financial or operating restrictions associated with debt financing) on smaller companies may be greater than that of larger or more established companies. The Fund may have more difficulty obtaining information about smaller companies, making it more difficult to evaluate the impact of market, economic,

regulatory and other factors on them. Informational difficulties may also make valuing or disposing of their securities more difficult than it would for larger companies. Securities of smaller companies may trade less frequently and in lesser volume than more widely held securities and the securities of smaller companies generally are subject to more abrupt or erratic price movements than more widely held or larger, more established companies or the market indices in general. The value of securities of smaller companies may react differently to political, market and economic developments than the markets as a whole or than other types of stocks.

Growth Stock Risk: Growth stocks may be more volatile than other stocks because they are more sensitive to investor perceptions of the issuing company’s growth potential. Growth stocks may go in and out of favor over time and may perform differently than the market as a whole.

Depositary Receipts Risk: Although depositary receipts have risks similar to the securities that they represent, they may also involve higher expenses and may trade at a discount (or premium) to the underlying security. In addition, depositary receipts may not pass through voting and other shareholder rights, and may be less liquid than the underlying securities listed on an exchange.

Volatility Risk: The smaller size and lower levels of liquidity in emerging markets, as well as other factors, may result in changes in the prices of Asian securities that are more volatile than those of companies in more developed regions. This volatility can cause the price of the Fund’s shares to go up or down dramatically. Because of this volatility, this Fund is better suited for long-term investors (typically five years or longer).

Information Technology Sector Risk: Information technology companies may be significantly affected by aggressive pricing as a result of intense competition and by rapid product obsolescence due to rapid development of technological innovations and frequent new product introduction. Other factors, such as short product cycle, possible loss or impairment of intellectual property rights, and changes in government regulations, may also adversely impact information technology companies.

Risks Associated with China and Hong Kong: The Chinese government exercises significant control over China’s economy through its industrial policies, monetary policy, management of currency exchange rates, and management of the payment of foreign currency- denominated obligations. Changes in these policies could adversely impact affected industries or companies in China. China’s economy, particularly its export-oriented industries, may be adversely impacted by trade or political disputes with China’s major trading partners, including the U.S. In addition, as its consumer class continues to grow, China’s domestically oriented industries may be especially sensitive to changes in government policy and investment cycles. If China were to exert its authority so as to alter the economic, political or legal structures or the existing social policy of Hong Kong, investor and business confidence in Hong Kong could be negatively affected and have an adverse effect on the Fund’s investments.

(expenses that you pay each year as a percentage of the value of your investment)

EXAMPLE OF FUND EXPENSES

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The example reflects the expense limitation for the one year period only. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example of fund expenses, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate for the Investor Class shares was 77% of the average value of its portfolio.

Principal Investment Strategy

Under normal market conditions, the Matthews China Small Companies Fund seeks to achieve its investment objective by investing at least 80% of its net assets, which include borrowings for investment purposes, in the common and preferred stocks of Small Companies (defined below) located in China. China includes its administrative and other districts, such as Hong Kong. A company or other issuer is considered to be “located” in a country or a region, and a security or instrument is deemed to be an Asian (or specific country) security or instrument, if it has substantial ties to that country or region. Matthews currently makes that determination based primarily on one or more of the following criteria: (A) with respect to a company or issuer, whether (i) it is organized under the laws of that country or any country in that region; (ii) it derives at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed, or has at least 50% of its assets located, within that country or region; (iii) it has the primary trading markets for its securities in that country or region; (iv) it has its principal place of business in or is otherwise headquartered in that country or region; or (v) it is a governmental entity or an agency, instrumentality or a political subdivision of that country or any country in that region; and (B) with respect to an instrument or issue, whether (i) its issuer is headquartered or organized in that country or region; (ii) it is issued to finance a project with significant assets or operations in that country or region; (iii) it is principally secured or backed by assets located in that country or region; (iv) it is a component of or its issuer is included in a recognized securities index for the country or region; or (v) it is denominated in the currency of an Asian country and addresses at least one of the other above criteria. The term “located” and the associated criteria listed above have been defined in such a way that Matthews has latitude in determining whether an issuer should be included within a region or country. The Fund may also invest in depositary receipts, including American, European and Global Depositary Receipts.

The Fund seeks to invest in smaller companies capable of sustainable growth based on the fundamental characteristics of those companies, including balance sheet information; number of employees; size and stability of cash flow; management’s depth, adaptability and integrity; product lines; marketing strategies; corporate governance; and financial health. Matthews determines whether a company should be considered to be a small company based on the size of its revenues, number of employees, net assets, the size and depth of its product line, level of development, and other factors compared to other companies in its industry, sector or region (“Small Companies”). The Fund may not invest in any company that has a market capitalization (the number of the company’s shares outstanding times the market price per share for such securities) higher than the greater of $3 billion or the market capitalization of the largest company included in the Fund’s primary benchmark index if, at the time of purchase, more than 20% of the Fund’s assets are already invested in such companies. The largest company in the Fund’s primary benchmark, the MSCI China Small Cap Index, had a market capitalization of $2.35 billion on December 31, 2018. Companies in which the Fund invests typically operate in growth industries and possess the potential to expand their scope of business over time. The Fund may continue to hold a security if its market capitalization increases above these levels

after purchase. The implementation of the principal investment strategies of the Fund may result in a significant portion of the Fund’s assets being invested from time to time in one or more sectors, but the Fund may invest in companies in any sector.

The value of securities of smaller companies may react differently to political, market and economic developments than the markets as a whole or than other types of stocks.

Risks Associated with China, Hong Kong and Taiwan:

China: The Chinese government exercises significant control over China’s economy through its industrial policies (e.g., allocation of resources and other preferential treatment), monetary policy, management of currency exchange rates, and management of the payment of foreign currency-denominated obligations. Changes in these policies could adversely impact affected industries or companies in China. China’s economy, particularly its export-oriented industries, may be adversely impacted by trade or political disputes with China’s major trading partners, including the U.S. In addition, as its consumer class continues to grow, China’s domestically oriented industries may be especially sensitive to changes in government policy and investment cycles. China’s currency, which historically has been managed in a tight range relative to the U.S. dollar, may in the future be subject to greater uncertainty as Chinese authorities change the policies that determine the exchange rate mechanism.

Hong Kong: If China were to exert its authority so as to alter the economic, political or legal structures or the existing social policy of Hong Kong, investor and business confidence in

Hong Kong could be negatively affected, which in turn could negatively affect markets and business performance and have an adverse effect on the Fund’s investments.

Taiwan: Although the relationship between China and Taiwan has been improving, there is the potential for future political or economic disturbances that may have an adverse impact on the values of investments in either China or Taiwan, or make investments in China and/or Taiwan impractical or impossible.

Growth Stock Risk: Growth stocks may be more volatile than other stocks because they are more sensitive to investor perceptions of the issuing company’s growth potential. Growth stocks may go in and out of favor over time and may perform differently than the market as a whole.

Depositary Receipts Risk: Although depositary receipts have risks similar to the securities that they represent, they may also involve higher expenses and may trade at a discount (or premium) to the underlying security. In addition, depositary receipts may not pass through voting and other shareholder rights, and may be less liquid than the underlying securities listed on an exchange.
