| 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. |
||||||||||||||||||||||||||||
| Shareholder Fees Caption [Text] | rr_ShareholderFeesCaption | Shareholder fees (fees paid directly from your investment) | ||||||||||||||||||||||||||||
| Operating Expenses Caption [Text] | rr_OperatingExpensesCaption | Annual fund operating expenses (expenses that you pay each year as a percentage of the value of your investment) | ||||||||||||||||||||||||||||
| 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 60.9% of the average value of its portfolio. |

| Expense Example [Heading] | rr_ExpenseExampleHeading | Example | ||||||||||||||||||||||||||||
| 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 stocks issued by companies that are located in, or that have economic ties to, Asia (excluding Japan). For purposes of determining whether the fund invests at least 80% of its net assets in Asian companies, the fund relies on the country assigned to a security by MSCI Inc., a third-party provider of benchmark indexes and data services, or another unaffiliated data provider. 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. The Asian countries in which the fund normally invests include, but are not limited to, the following: · Primary Emphasis: China, Hong Kong, India, Indonesia, Malaysia, Philippines, Singapore, South Korea, Taiwan, and Thailand. · Others: Pakistan, Sri Lanka, and Vietnam. The fund is “nondiversified,” meaning it may invest a greater portion of its assets in a single issuer and own more of the issuer’s voting securities than is permissible for a “diversified” fund. The fund may purchase stocks issued by companies of any size, but typically focuses its investments on large- and mid-cap stocks. At times, the fund may have a significant portion of its assets invested in the same economic sector, such as the financial sector. While the adviser invests with an awareness of the adviser’s outlook for certain industries, sectors, and individual countries within the region, the adviser’s decision-making process focuses on bottom-up stock selection. Country allocation is driven largely by stock selection, though the adviser may limit investments in markets or industries that appear to have poor overall prospects. The fund does not normally emphasize either a growth or value bias in selecting investments. The fund relies on a global team of investment analysts dedicated to in-depth fundamental research in an effort to identify high-quality companies with the potential to reliably compound earnings and sustain strong cash flows over time. The adviser seeks stocks of companies at reasonable prices in relation to present or anticipated earnings, cash flow, or book value, and selects those stocks that the adviser believes have the most favorable combination of company fundamentals, earnings potential, and relative valuation. In selecting investments, the adviser generally favors companies with one or more of the following characteristics: · well-established and with leading market positions; · attractive business niche with the potential to sustain earnings even during times of slow economic growth; · competitive advantages in an attractive industry; · proven management with high governance standards; · demonstrated ability to consistently increase revenues, earnings, and/or cash flows; and · prudent capital allocation and balance sheet management. |

| T. Rowe Price Asia Opportunities Fund | Investing in Asia | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Investing in Asia: Many Asian economies have at various times been negatively affected by inflation, currency devaluations, an over-reliance on international trade and exports, particularly for certain commodities, political and social instability, and less developed financial systems and securities trading markets. Trade restrictions, unexpected decreases in exports, changes in government policies, expropriation and/or nationalization of assets, confiscatory taxation, or natural disasters could have a significant impact on companies doing business in Asia. The Asian region may be significantly affected by political unrest, military conflict, economic sanctions, and less demand for Asian products and services. |
||||||||||||||||||||||||||||
| T. Rowe Price Asia Opportunities 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 Asia Opportunities Fund | Investing in India | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Investing in India: The securities markets in India are smaller, less liquid and more volatile than the securities markets of developed countries. The Indian markets are prone to periods of growth and change, which may result in trading or price volatility and difficulties in the settlement and recording of transactions. Inflation and rapid fluctuations in inflation and interest rates have had, and may continue to have, negative effects on the economy and securities markets of India. In addition, India is susceptible to natural disasters and border disputes, and governmental actions can have a significant effect on the economic conditions in the India region, which could adversely affect the value and liquidity of investments in India. |
||||||||||||||||||||||||||||
| T. Rowe Price Asia Opportunities 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 Asia Opportunities 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 Asia Opportunities Fund | Frontier markets | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Frontier markets: Frontier markets generally have smaller economies and less mature capital markets than emerging markets. As a result, the risks associated with investing in emerging market countries are magnified in frontier market countries. Frontier markets are more susceptible to abrupt changes in currency values, have less mature markets and settlement practices, and can have lower trading volumes that could lead to greater price volatility and illiquidity. Investor protections in frontier market countries may be limited and settlement procedures and custody services may prove inadequate in certain markets. |
||||||||||||||||||||||||||||
| T. Rowe Price Asia Opportunities 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 Asia Opportunities 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 Asia Opportunities Fund | Financial sector | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Financial sector: Because the fund may invest significantly in banks and other financial services companies, the fund is more susceptible to adverse developments affecting such companies and may perform poorly during a downturn that impacts the financial sector. Banks and other financial services companies can be adversely affected by, among other things, regulatory changes, interest rate movements, the availability of capital and cost to borrow, and the rate of debt defaults. |
||||||||||||||||||||||||||||
| T. Rowe Price Asia Opportunities 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 Asia Opportunities 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 Asia Opportunities Fund | Risk Nondiversified Status [Member] | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Nondiversification: As a nondiversified fund, the fund has the ability to invest a larger percentage of its assets in the securities of a smaller number of issuers than a diversified fund. As a result, poor performance by a single issuer could adversely affect fund performance more than if the fund were invested in a larger number of issuers. The fund’s share price can be expected to fluctuate more than that of a similar fund that is more broadly diversified. |
||||||||||||||||||||||||||||
| T. Rowe Price Asia Opportunities 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 Asia Opportunities Fund | Large- and mid-cap stocks | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Large- and mid-cap stocks: Securities issued by large- and mid-cap companies tend to be less volatile than securities issued by small-cap companies. However, large-cap companies may not be able to attain the high growth rates of successful small-cap companies, especially during strong economic periods, and may be unable to respond as quickly to competitive challenges. The fund’s share price could fluctuate more than the share price of a fund that invests only in large-cap companies as stocks of mid-cap companies entail greater risk and are usually more volatile than stocks of large-cap companies. |
||||||||||||||||||||||||||||
| T. Rowe Price Asia Opportunities 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 Asia Opportunities 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. |
