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 51.1% of the average value of its portfolio.

Portfolio Turnover, Rate rr_PortfolioTurnoverRate 51.10%
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 in emerging markets. The fund relies on MSCI Inc., a third-party provider of benchmark indexes and data services, or another unaffiliated data provider to determine the country assigned to a security and whether the country is considered an emerging market. The fund considers frontier markets to be a subset of emerging markets and any investments in frontier markets are counted toward the fund’s 80% investment policy. 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 fund expects to primarily invest in common stocks of companies located (or with primary operations) in emerging markets (which may include frontier markets) in Asia, Latin America, Europe, Africa, and the Middle East. The countries in which the fund normally invests include, but are not limited to, the following:

· Asia: China, India, Indonesia, Malaysia, Pakistan, Philippines, South Korea, Sri Lanka, Taiwan, Thailand, and Vietnam.

· Latin America: Argentina, Belize, Brazil, Chile, Colombia, Mexico, Panama, Peru, and Venezuela.

· Europe: Croatia, Czech Republic, Estonia, Greece, Hungary, Kazakhstan, Latvia, Lithuania, Poland, Romania, Slovakia, Slovenia, Türkiye, and Ukraine.

· Africa and the Middle East: Bahrain, Botswana, Egypt, Jordan, Kenya, Kuwait, Lebanon, Mauritius, Morocco, Nigeria, Oman, Qatar, Saudi Arabia, South Africa, Tunisia, United Arab Emirates, and Zimbabwe.

The fund may invest in companies of any size, but generally seeks stocks of large-cap companies that are undervalued in the view of the portfolio manager using various measures. While the adviser invests with an awareness of the global economic backdrop and the adviser’s outlook for certain industries, sectors, and individual countries, 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 may, at times, invest significantly in Asia and specifically, China.

At times, the fund may have a significant portion of its assets invested in the same economic sector, such as the financial sector.

Stock selection is driven mainly by fundamental research focused on individual companies. The fund’s value approach to investing relies on a global research team that searches for companies that appear to be undervalued by various measures and may be temporarily out of favor but have good prospects for long-term capital appreciation or dividend growth.

In selecting investments, the adviser generally favors companies with one or more of the following characteristics:

· low valuation on various earnings, book value, sales, and cash flow metrics, in absolute terms and/or relative to the company’s peers or its own historical norm;

· low valuation relative to a company’s fundamentals;

· companies that may benefit from restructuring activity or other turnaround opportunities;

· a sound balance sheet and other positive financial characteristics;

· strong or improving position in an overlooked industry or country; and

· above-average dividend yield and/or the potential to grow dividends.

T. Rowe Price Emerging Markets Discovery Stock 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 Emerging Markets Discovery Stock 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 Emerging Markets Discovery Stock 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 Emerging Markets Discovery Stock 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 Emerging Markets Discovery Stock Fund | Investing in China  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Investing in China: The Chinese government has historically exercised significant control over China’s economy and its financial markets through, among other things, its monetary policies and allocation of resources, management of currency exchange rates, preferential treatment or restrictions relating to industries deemed sensitive to national interests, and limitations on foreign ownership of Chinese securities. Although economic reforms have liberalized trade policy and reduced government control, changes in these policies or increased government intervention could adversely impact affected industries or companies. China’s currency, which historically has been managed in a tight range relative to the U.S. dollar, may in the future be subject to greater uncertainty as Chinese authorities change the policies that determine the official currency exchange rate. Additionally, the Chinese economy is highly dependent on the exportation of products and services, and could experience a significant slowdown due to a reduction in global demand for Chinese exports, contraction in spending on domestic goods by Chinese consumers, trade or political disputes with China’s major trading partners, imposition of tariffs, sanctions, and other trade barriers, military conflict and strained international relations, cyberattacks, natural disasters, or public health threats. Heightened trade tensions between China and any of its key trading partners, including the U.S., could have a significant adverse impact on the Chinese economy.

T. Rowe Price Emerging Markets Discovery Stock 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 Emerging Markets Discovery Stock 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 Emerging Markets Discovery Stock 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 Emerging Markets Discovery Stock Fund | Currency exposure  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Currency exposure: Because the fund is normally heavily exposed to foreign currencies, the fund is subject to the significant risk that it could experience losses based solely on the weakness of foreign currencies versus the U.S. dollar and changes in the exchange rates between such currencies and the U.S. dollar.

T. Rowe Price Emerging Markets Discovery Stock Fund | Value investing  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Value investing: The fund’s value approach to investing could cause it to underperform other stock funds that employ a different investment style. The intrinsic value of a stock with value characteristics may not be fully recognized by the market for a long time (or at all) or a stock judged to be undervalued may actually be appropriately priced at a low level. Value stocks may fail to appreciate for long periods and may never reach what the adviser believes are their full market values.

T. Rowe Price Emerging Markets Discovery Stock 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 Emerging Markets Discovery Stock Fund | Large-cap stocks  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Large-cap stocks: Securities issued by large-cap companies tend to be less volatile than securities issued by small- and mid-cap companies. However, large-cap companies may not be able to attain the high growth rates of successful small- and mid-cap companies, especially during strong economic periods, and may be unable to respond as quickly to competitive challenges.

T. Rowe Price Emerging Markets Discovery Stock 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 Emerging Markets Discovery Stock 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.
