PORTFOLIO TURNOVER

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. Because the Fund is newly formed and commenced operations on April 30, 2015, no portfolio turnover rate data is available for the Fund.

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:

Principal Investment Strategy

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

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 the 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 is considered to be “located” in a country or a region if it has substantial ties to that country or region, and currently, Matthews makes that determination primarily based on one or more of the following five criteria: if the company (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; (iv) has its principal place of business in or is otherwise headquartered in that country or region; or (v) 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 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 across the market capitalization spectrum that Matthews believes to be undervalued but of high quality and run by management teams with good operating and governance track records. 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. Examples of environmental factors that may be considered include, without limitation, low environmental footprint, pollution alleviation, and resource management. Examples of social factors that may be considered include, without limitation, financial inclusion, affordable products and services, workplace diversity and employee welfare. Examples of governance factors that may be considered include, without limitation, board independence, stated sustainability policy, and alignment of interests of shareholders and management. 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 meets 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 that promotes positive social and economic developments. The Fund intends to engage its portfolio companies on ESG matters through active dialogue and proxy voting and by encouraging enhanced ESG disclosure.

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.

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).

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, that same company may also fail to satisfy other ESG standards, in some cases even egregiously.

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 Investors Service, Inc. (“Moody’s”), Standard and Poor’s Corporation (“S&P”) and Fitch Inc. (“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.

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 predominately speculative. They may also be more susceptible to adverse economic and competitive industry conditions than higher-rated securities.

Risks Associated with Smaller and Medium-Size Companies: Smaller and 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.

[1] "Other Expenses" for the Fund are based on estimated amounts for the current fiscal year.

[2] Matthews has contractually agreed (i) to waive fees and reimburse expenses to the extent needed to limit Total Annual Fund Operating Expenses (excluding Rule 12b-1 fees, front-end or contingent deferred loads, taxes, interest, brokerage commissions, short sale dividend expenses, expenses incurred in connection with any merger or reorganization or extraordinary expenses such as litigation) of the Institutional Class to 1.25%, and (ii) if any Fund-wide expenses (i.e., expenses that apply to both the Institutional Class and the Investor Class) are waived for the Institutional Class to maintain the 1.25% expense limitation, to waive an equal amount (in annual percentage terms) of those same expenses for the Investor Class. The Total Annual Fund Operating Expenses After Fee Waiver and Expense Reimbursement for the Investor Class may vary from year to year and will in some years exceed 1.25%. If the operating expenses fall below the expense limitation in a year within three years after Matthews has made a waiver or reimbursement, the Fund may reimburse Matthews up to an amount that does not cause the expenses for that year to exceed the expense limitation applicable at the time of that fee waiver and/or expense reimbursement or to exceed any other agreed upon expense limitation for that year. This agreement will remain in place until April 30, 2017, may be renewed for additional periods not exceeding one year and may be terminated at any time by the Board of Trustees or the Trust on behalf of the Fund on 60 days' written notice to Matthews. Matthews may decline to renew this agreement by written notice to the Trust at least 30 days before its annual expiration date.
