Expense, Narrative	rr_ExpenseNarrativeTextBlock	This table describes the fees and expenses that you may pay if you buy and hold shares of this Fund.
Shareholder Fees, Caption	rr_ShareholderFeesCaption	SHAREHOLDER FEES (fees paid directly from your investment)

Portfolio Turnover, Heading	rr_PortfolioTurnoverHeading	PORTFOLIO TURNOVER
Portfolio Turnover	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 11% of the average value of its portfolio.

Expense Example, Heading	rr_ExpenseExampleHeading	EXAMPLE OF FUND EXPENSES
Expense Example, Narrative	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:
Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategy
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Matthews Pacific Tiger Fund seeks to achieve its investment objective by investing at least 80% of its total 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. The location of a company can be determined by where it is organized, where its revenues and profits are derived, where its assets are located, or other factors. 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	rr_RiskNarrativeTextBlock	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 emerging and frontier markets. Their stock exchanges and brokerage industries typically do not have the level of government oversight as do those in the United States. Securities markets of such countries are 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).
