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 46% of the average value of its portfolio.

Strategy Narrative [Text Block]

Under normal circumstances, the Matthews Japan Active ETF 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 Japan, and a security or instrument is deemed to be a Japanese security or instrument, if it has substantial ties to Japan. 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 Japan; (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 Japan; (iii) it has the primary trading markets for its securities in Japan; (iv) it has its principal place of business in or is otherwise headquartered in Japan; or (v) it is a governmental entity or an agency, instrumentality or a political subdivision of Japan; and (B) with respect to an instrument or issue, whether (i) its issuer is headquartered or organized in Japan; (ii) it is issued to finance a project that has at least 50% of its assets or operations Japan; (iii) it is at least 50% secured or backed by assets located in Japan; (iv) it is a component of or its issuer is included in the MSCI Japan Index, the Fund’s primary benchmark index; or (v) it is denominated in the currency of Japan 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. Matthews may rely on only one criterion to determine location even if other criteria point to a different location. The Fund may also invest in depositary receipts, including American, European and Global Depositary Receipts. The Fund may invest up to 20% of its net assets in debt securities, including securities issued by government entities and their political subdivisions.

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.

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.

Geopolitical Events Risk: The interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate-related events, pandemics, epidemics, terrorism, international conflicts, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on the global financial markets.

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.

Risk [Text Block]

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.

Equity Securities Risk: Equity securities may include common stock, preferred stock or other securities representing an ownership interest or the right to acquire an ownership interest in an issuer. Equity risk is the risk that stocks and other equity securities generally fluctuate in value more than bonds and may decline in value over short or extended periods. The value of stocks and other equity securities may be affected by changes in an issuer’s financial condition, factors that affect a particular industry or industries, or as a result of changes in overall market, economic and political conditions that are not specifically related to a company or industry.

Preferred Stock Risk: Preferred stock normally pays dividends at a specified rate and has precedence over common stock in the event the issuer is liquidated or declares bankruptcy. However, in the event a company is liquidated or declares bankruptcy, the claims of owners of bonds take precedence over the claims of those who own preferred and common stock. If interest rates rise, the dividend on preferred stocks may be less attractive, causing the price of such stocks to decline.

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.

Risk/Return:

rr_RiskReturnAbstract

Risk [Text Block]

ETF Risks: The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:

Authorized Participants, Market Makers, and Liquidity Providers Limitation Risk: Only an Authorized Participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that may act as APs, and none of these APs are or will be obligated to engage in creation or redemption transactions. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace with respect to the Fund’s shares. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face trading halts and/or delisting (that is, investors would no longer be able to trade the Fund’s shares in the secondary market): (i) APs exit the business or otherwise become unable to process creation and/or redemption orders (including in situations where APs have limited or diminished access to capital required to post collateral), and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

Cash Redemption Risk: Unlike many ETFs, the Fund’s investment strategy may require it to redeem shares of the Fund for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in‑kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in‑kind redemption process was used. Cash redemptions may also entail higher transaction costs than in‑kind redemptions, which costs may be passed on to redeemers of creation units of Fund shares in the form of redemption transaction fees. The cost of cash redemptions could also reduce the Fund’s NAV to the extent that those costs are not fully offset by the redemption transaction fee charged to the redeeming Authorized Participant.

Costs of Buying or Selling Shares: Due to the costs of buying or selling, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments. The bid/ask spread of the Fund’s shares varies over time based on the Fund’s trading volume and market liquidity and may increase if the Fund’s trading volume, the spread of the Fund’s underlying securities, or market liquidity decrease. In times of severe market disruption, including when trading of the Fund’s holdings may be halted, the bid/ask spread may increase significantly. This means that Fund shares may trade at a discount to the Fund’s NAV, and the discount is likely to be greatest during significant market volatility. During such periods, you may be unable to sell your shares or may incur significant losses if you sell your shares. There are various methods by which investors can purchase and sell shares of the Fund and various orders that may be placed. Investors should consult their financial intermediary before purchasing or selling shares of the Fund.

Large Shareholder Risk: Shares of the Fund may be owned from time to time by one or more large shareholders, including Authorized Participants, market makers, third party investors, Matthews or affiliates of Matthews or the Fund. Redemptions by large shareholders could have a sig-

nificant negative impact on the Fund. If a large shareholder were to redeem all, or a large portion, of its shares, the Fund may be forced to selling securities when it otherwise would not have done so, accelerating the realization of capital gains, and increasing transaction costs. In addition, transactions by large shareholders may account for a large percentage of the trading volume on a national securities exchange causing reduced liquidity or have a material effect on the market price of the shares of the Fund.

Shares May Trade at Prices Other Than NAV: As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. Although the creation/redemption feature is designed to help the market price of Fund shares approximate the Fund’s NAV, market prices are not expected to correlate exactly to the Fund’s NAV and there may be times when the market price of Fund shares is more than the intra‑day value of the Fund’s holdings (premium) or less than the intra‑day value of the Fund’s holdings (discount) due to supply and demand of the Fund’s shares, during periods of market volatility or for other reasons. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Fund shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases shares of the Fund at a time when the market price is at a premium to the NAV of the shares or sells at a time when the market price is at a discount to the NAV of the shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV. Given the nature of the relevant markets for certain of the securities for the Fund, shares may trade at a larger premium or discount to NAV than shares of other kinds of ETFs. In addition, the securities held by the Fund may be traded in markets that close at a different time than the exchange on which the shares are listed. Liquidity in those securities may be reduced after the applicable closing times. Accordingly, during the time when the exchange is open but after the applicable market closing, fixing or settlement times, bid/ask spreads and the resulting premium or discount to the NAV of Fund shares may widen.

Trading: Although shares of the Fund are listed for trading on a national securities exchange, and may be traded on other U.S. exchanges, there can be no assurance that the shares will trade with any volume, or at all, on any stock exchange. Because the Fund is new, no trading market for its shares may develop. In stressed market conditions, the liquidity of shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund. Trading in Fund shares on the exchange may be halted due to market conditions or for reasons that, in the view of the exchange, make trading in shares inadvisable. In addition, trading in Fund shares on the exchange is subject to trading halts caused by extraordinary market volatility pursuant to the exchange “circuit breaker” rules. If a trading halt or unanticipated early closing of the exchange occurs, a shareholder may be unable to purchase or sell shares of the Fund. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Sector Concentration Risk: To the extent that the Fund emphasizes, from time to time, investments in a particular sector, the Fund will be subject to a greater degree to the risks particular to that sector, including the sector described below. Market conditions, interest rates, and economic, regulatory, or financial developments could significantly affect a single sector. By focusing its investments in a particular sector, the Fund may face more risks than if it were diversified broadly over numerous sectors.

–

Information Technology Sector Risk: As of December 31, 2023, 21% of the Fund’s assets were invested in the information technology sector. 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.

–

Consumer Discretionary Sector Risk: As of December 31, 2023, 20% of the Fund’s assets were invested in the consumer discretionary sector. The success of consumer product manufacturers and retailers is tied closely to the performance of the overall local and international economies, 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.
