Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

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 2% of the average value of its portfolio.

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock

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:

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 is considered to be “located” in a country or a region if it has substantial ties to that country or region, including for example, if it (i) is organized under the laws of that country or any country in that region; (ii) 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) has the primary trading markets for its securities in that country or region; or (iv) is a governmental entity or an agency, instrumentality or a political subdivision of that country or any country in that region. The Fund may also invest in the convertible securities, of any duration or quality, of companies located in Asia excluding Japan, South Korea, Hong Kong and Singapore.


Once fully invested and under normal market conditions, the Fund is expected to invest 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.

Risk [Heading] rr_RiskHeading Principal Risks of Investment
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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: 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 Asian region, and particularly China, Japan and South Korea, may be adversely affected by political, military, economic and other factors related to North Korea. In addition, China’s long-running conflict over Taiwan, border disputes with many of its neighbors and historically strained relations with Japan could adversely impact economies in the region. 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. Certain Asian countries are highly dependent upon and may be affected by developments in the United States, Europe and other Asian economies.


Currency Risks: 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 dollar terms if that currency weakens against the 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. 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.


Trading Markets and Depositary Receipts: Asian securities may trade in the form of depositary receipts, including American, European and Global Depositary Receipts. 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: 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 (NAV) to go up or down dramatically. Because of this volatility, it is recommended that you invest in the Fund only for the long term (at least five years).


Convertible Securities: 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 like Moody’s, S&P or Fitch, or, if they are rated, they may be rated below investment grade (these are referred to as “junk bonds,” which are primarily speculative securities, and include unrated securities, regardless of quality), which may have a greater risk of default. Investments in convertible securities may also subject the Fund to currency risk and risks associated with foreign exchange rate. Convertible securities may trade less frequently and in lower volumes, making it difficult for the Fund to value those 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. 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) may be greater than in 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 such 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.


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.

[1] Matthews has contractually agreed to waive fees and reimburse expenses until August 31, 2015 to the extent needed to limit Total Annual Fund Operating Expenses to 1.25% for the Institutional Class. If the expenses fall below the expense limitation in a year within three years after Matthews has made such a waiver or reimbursement, the Fund may reimburse Matthews up to an amount not to cause the expenses for that year to exceed the expense limitation. The fee waiver and expense reimbursement may be terminated at any time by the Board of Trustees or the Trust on behalf of the Fund on 60 days' written notice.
