| Expense Narrative [Text Block] | rr_ExpenseNarrativeTextBlock | This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the fund. You may also incur brokerage commissions and other charges when buying or selling shares of the fund, which are not reflected in the table or example below. |

| Portfolio Turnover [Heading] | rr_PortfolioTurnoverHeading | Portfolio Turnover | ||||||||||||||||||||||||||||
| Portfolio Turnover [Text Block] | rr_PortfolioTurnoverTextBlock | 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 rate may indicate higher transaction costs and may result in higher taxes when the fund’s shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 82.4% 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, that your investment has a 5% return each year, and that the fund’s operating expenses remain the same. The example also assumes that any current expense limitation arrangement remains in place for the period noted in the previous table; therefore, the figures have been adjusted to reflect fee waivers or expense reimbursements only in the periods for which the expense limitation arrangement is expected to continue. Although your actual costs may be higher or lower, based on these assumptions your costs would be: | ||||||||||||||||||||||||||||
| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | ||||||||||||||||||||||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities and equity related investments of Chinese companies. For purposes of this 80% investment policy, the fund considers companies in Greater China, including the People’s Republic of China, Hong Kong, Macau, and Taiwan, to be Chinese companies. Any derivatives that provide exposure to the investment focus suggested by the fund’s name, or to one or more market risk factors associated with the investment focus suggested by the fund’s name, are counted (as applicable) toward compliance with the fund’s 80% investment policy. Chinese companies include those that meet one or more of the following criteria (or any other factor utilized by MSCI Inc. or another third party provider): · organized in Greater China; · principally located in, or headquartered in, Greater China; · trading markets for their securities are located in Greater China; · business activities are predominantly conducted in Greater China, or a significant portion (e.g., at least 50%) of their revenues or profits are derived from Greater China; · geographic distribution of the company’s shareholder base is predominantly in Greater China; · the company is controlled by individuals or entities that are considered Greater Chinese; or · securities are reported in a Greater Chinese currency, including the Renminbi (RMB), mainland China’s currency, and the Hong Kong dollar. Equity securities may include common and preferred stocks. The fund may also gain exposure to Chinese equities through depositary receipts and equity-linked certificates or notes. The fund may purchase the stocks of companies of any size but typically emphasizes investments in small- and mid-cap companies. At times, the fund may have a significant portion of its assets invested in the same economic sector. The fund may invest in Chinese companies listed on the Shanghai and Shenzhen Stock Exchanges such as “A-shares” (which are denominated in RMB) and shares of Chinese companies denominated in other currencies (such as the Hong Kong dollar or U.S. dollar) that trade in China, Hong Kong, Taiwan, the United States, or otherwise outside of China. In addition to investments in Chinese companies, the fund may also invest up to 20% of its net assets in companies in other countries or markets, such as Japan or South Korea. Many of the areas in which the fund invests, including China, Macau, Taiwan and South Korea, are considered emerging markets. The fund’s adviser relies on a global team of investment analysts dedicated to in-depth fundamental research in an effort to identify companies for the fund’s portfolio. The adviser takes a style-agnostic approach and aims to identify mispriced companies with opportunities driven by change. The types of change the adviser focuses on include: · new technology or unique product offerings; · significant market share; · product cycle opportunities; · attractive or improving industry or sector; and · companies expected to benefit from management changes, regulatory changes, or new business models. The adviser also considers the following key characteristics of each company: · management’s depth, adaptability and integrity; · overall financial health and stability of cash flow; and · attractive valuation. |

| T. Rowe Price China Evolution Equity Fund | Investing in Greater China | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Investing in Greater China: Investments in companies in Greater China, whether listed in mainland China or listed in another market, are subject to special risks, such as less developed or less efficient trading markets, currency fluctuations, nationalization of assets, limits on repatriation, and the effects of governmental control of markets. Chinese markets generally continue to experience inefficiency, volatility, and pricing anomalies resulting from governmental influence, a lack of publicly available information, and/or political and social instability. Internal social unrest or confrontations with neighboring countries may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency non-convertibility, interest rate fluctuations, and higher rates of inflation. Investments in Chinese companies are subject to China’s heavy dependence on exports. China’s economy may be adversely impacted by trade or political disputes (including the institution of additional tariffs or other trade barriers), reduction in spending on Chinese products and services, or a downturn in any of the economies of China’s major trading partners, including the U.S. A small number of companies and industries represent a relatively large portion of the Chinese market as a whole. Monsoons and other natural disasters, or public health threats, may cause substantial adverse economic affects. The Shanghai and Shenzhen stock exchanges may close for extended periods for holidays or otherwise, which impacts the fund’s ability to trade in A Shares during those periods. In addition, 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 or Taiwan, investor and business confidence in Hong Kong or Taiwan could be negatively affected, which in turn could negatively affect markets and business performance and have an adverse effect on the fund’s investments. China has experienced security concerns, such as terrorism and strained international relations. Additionally, China is alleged to have participated in state-sponsored cyberattacks against foreign companies and foreign governments. Actual and threatened responses to such activity, including purchasing restrictions, sanctions, tariffs, or cyberattacks on the Chinese government or Chinese companies may impact China’s economy and Chinese issuers of securities in which the fund invests. Chinese companies, including Chinese companies that are listed on U.S. exchanges, are not subject to the same degree of regulatory requirements, accounting standards, or auditor oversight as companies in more developed countries and, as a result, information about the Chinese securities in which the fund invests may be less reliable or complete. There may be significant obstacles to obtaining information necessary for investigations into or litigation against Chinese companies and shareholders may have limited legal remedies. In addition, there may be restrictions on investments in Chinese companies. |
||||||||||||||||||||||||||||
| T. Rowe Price China Evolution Equity Fund | Geographic concentration | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Geographic concentration: Because the fund focuses its investments on a particular geographic area, the fund’s performance is closely tied to the social, political, and economic conditions of that area. Political developments and changes in regulatory, tax, or economic policy could significantly affect the markets in which the fund invests. As a result, the fund is likely to be more volatile than more geographically diverse international funds. |
||||||||||||||||||||||||||||
| T. Rowe Price China Evolution Equity Fund | Small- and mid-cap stocks | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Small- and mid-cap stocks: Investments in securities issued by small- and mid-cap companies are likely to be more volatile than investments in securities issued by larger companies. Small- and mid-cap companies often have less experienced management, narrower product lines, more limited financial resources, and less publicly available information than larger companies. In addition, small-cap companies tend to be more sensitive to changes in overall economic conditions and their securities may have limited trading markets. |
||||||||||||||||||||||||||||
| T. Rowe Price China Evolution Equity Fund | Emerging markets | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Emerging markets: Investments in emerging market countries are subject to greater risk and overall volatility than investments in the U.S. and other developed markets. Emerging market countries tend to have economic structures that are less diverse and mature, less developed legal and regulatory regimes, and political systems that are less stable, than those of developed countries. In addition to the risks associated with investing outside the U.S., emerging markets are more susceptible to governmental interference, political and economic uncertainty, local taxes and restrictions on the fund’s investments, less efficient trading markets with lower overall liquidity, and more volatile currency exchange rates. |
||||||||||||||||||||||||||||
| T. Rowe Price China Evolution Equity Fund | International investing | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | International investing: Non-U.S. securities tend to be more volatile and have lower overall liquidity than investments in U.S. securities and may lose value because of adverse local, political, social, or economic developments overseas, or due to changes in the exchange rates between foreign currencies and the U.S. dollar. In addition, investments outside the U.S. are subject to settlement practices and regulatory and financial reporting standards that differ from those of the U.S. The risks of investing outside the U.S. are heightened for any investments in emerging markets, which are susceptible to greater volatility than investments in developed markets. |
||||||||||||||||||||||||||||
| T. Rowe Price China Evolution Equity Fund | Chinese currency exposure | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Chinese currency exposure: Because the fund invests significantly in securities denominated in RMB and other foreign currencies, the fund is subject to the significant risk that it could experience losses based solely on the weakness of the RMB and other foreign currencies versus the U.S. dollar and changes in the exchange rates between such currencies and the U.S. dollar. 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, and may negatively affect the value of the fund’s holdings. |
||||||||||||||||||||||||||||
| T. Rowe Price China Evolution Equity Fund | Stock investing | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Stock investing: Stocks generally fluctuate in value more than bonds and may decline significantly over short time periods. There is a chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising and falling prices. The value of stocks held by the fund may decline due to general weakness or volatility in the stock markets in which the fund invests or because of factors that affect a particular company or industry. |
||||||||||||||||||||||||||||
| T. Rowe Price China Evolution Equity Fund | Market conditions | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Market conditions: The value of the fund’s investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting an issuer held by the fund, particular industries, or the overall securities markets. A variety of factors can increase the volatility of the fund’s holdings and markets generally, including economic, political, or regulatory developments, recessions, inflation, rapid interest rate changes, war, military conflict, acts of terrorism, natural disasters, and outbreaks of infectious illnesses or other widespread public health issues (such as the coronavirus pandemic) and related governmental and public responses (including sanctions). Certain events may cause instability across global markets, including reduced liquidity and disruptions in trading markets, while some events may affect certain geographic regions, countries, sectors, and industries more significantly than others. Government intervention in markets may impact interest rates, market volatility, and security pricing. These adverse developments may cause broad declines in market value due to short-term market movements or for significantly longer periods during more prolonged market downturns. |
||||||||||||||||||||||||||||
| T. Rowe Price China Evolution Equity Fund | Liquidity | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Liquidity: A particular investment or an entire market segment may become less liquid or even illiquid, sometimes abruptly, which could limit the fund’s ability to purchase or sell holdings in a timely manner at a desired price. An inability to sell a portfolio holding can adversely affect the fund’s overall value or prevent the fund from being able to take advantage of other investment opportunities. Liquidity risk may be magnified during periods of substantial market volatility and unexpected episodes of illiquidity may limit the fund’s ability to pay redemption proceeds without selling holdings at an unfavorable time or at a suitable price. Large redemptions may also have a negative impact on the fund’s overall liquidity. |
||||||||||||||||||||||||||||
| T. Rowe Price China Evolution Equity Fund | Sector exposure | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Sector exposure: Issuers in the same economic sector may be similarly affected by economic or market events, making the fund more vulnerable to unfavorable developments in that economic sector than funds that invest more broadly. |
||||||||||||||||||||||||||||
| T. Rowe Price China Evolution Equity Fund | Depositary receipts | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Depositary receipts: Investing in depositary receipts involves substantially the same risks as direct investments in foreign securities. In addition, the underlying issuers of certain depositary receipts are under no obligation to distribute shareholder communications or pass through any voting rights with respect to the deposited securities to the holders of such receipts. The fund may therefore receive less timely information or have less control than if it invested directly in the foreign issuer. |
||||||||||||||||||||||||||||
| T. Rowe Price China Evolution Equity Fund | Active management | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Active management: The fund’s overall investment program and holdings selected by the fund’s investment adviser may underperform the broad markets, relevant indices, or other funds with similar objectives and investment strategies. |
||||||||||||||||||||||||||||
| T. Rowe Price China Evolution Equity Fund | Cybersecurity breaches | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Cybersecurity breaches: The fund could be harmed by intentional cyberattacks and other cybersecurity breaches, including unauthorized access to the fund’s assets, confidential information, or other proprietary information. In addition, a cybersecurity breach could cause one of the fund’s service providers or financial intermediaries to suffer unauthorized data access, data corruption, or loss of operational functionality. |
