| Objective [Heading] | rr_ObjectiveHeading | Investment Objective(s) | ||||||||||||||||||||||||||||
| Objective, Primary [Text Block] | rr_ObjectivePrimaryTextBlock | The fund seeks long-term growth of capital through investments primarily in the common stocks of companies located (or with primary operations) in Latin America. |

| Expense [Heading] | rr_ExpenseHeading | Fees and Expenses | ||||||||||||||||||||||||||||
| 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 23.2% 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 Latin American companies. For purposes of determining whether the fund invests at least 80% of its net assets in Latin American companies, 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. 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. Under normal conditions, at least four countries will be represented in the fund’s portfolio. The fund expects to primarily invest in the equity securities, including common stocks, preferred stocks, and convertible securities, of companies located (or with primary operations) in Latin America. The countries in which the fund normally invests include, but are not limited to, the following: · Primary Emphasis: Argentina, Brazil, Chile, Colombia, Mexico, and Peru. · Others: Belize, Ecuador, Guatemala, Panama, and Venezuela. The fund typically has substantial investments in Brazil and Mexico. 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 of companies of any size. 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. Security selection reflects a growth style. The adviser relies on a global team of investment analysts dedicated to in-depth fundamental research in an effort to identify companies capable of achieving and sustaining above-average, long-term earnings growth. The adviser seeks to purchase stocks of companies at reasonable prices in relation to present or anticipated earnings, cash flow, or book value. In selecting investments, the adviser generally favors companies with one or more of the following characteristics: · leading or improving market position; · attractive business niche; · attractive or improving franchise or industry position; · seasoned management; · stable or improving earnings and/or cash flow; and · sound or improving balance sheet. At times, the fund may have a significant portion of its assets invested in the same economic sector, such as the financial sector. |

| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | The fund’s share price fluctuates, which means you could lose money by investing in the fund. | ||||||||||||||||||||||||||||
| T. Rowe Price Latin America Fund | Investing in Latin America | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Investing in Latin America: Many Latin American countries have histories of inflation, government overspending, political and economic instability, social unrest, high interest and unemployment rates, and extreme currency fluctuations. Many of these countries tend to be highly reliant on the exportation of commodities so their economies may be significantly impacted by fluctuations in commodity prices and the global demand for certain commodities. |
||||||||||||||||||||||||||||
| T. Rowe Price Latin America 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 Latin America Fund | Investing in Brazil | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Investing in Brazil: The Brazilian economy, like many Latin American economies, is susceptible to inflation, monetary tightening and other governmental controls, slowing growth in its primary export markets, a high level of debt, and social tensions and corruption. Brazil has a volatile political history and is heavily dependent on external financing and exports to developed countries. The Brazilian government may impose temporary restrictions on remitting proceeds from the sale of Brazilian securities to foreign investors, such as the fund. |
||||||||||||||||||||||||||||
| T. Rowe Price Latin America 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 Latin America 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 Latin America Fund | Investing in Mexico | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Investing in Mexico: The Mexican economy relies heavily on its partnership with the U.S. and is therefore vulnerable to any changes in the free trade agreement. Mexico’s competitiveness has suffered from the rise of organized crime and lack of reforms in the energy sector and tax regulations. Other factors negatively impacting the Mexican economy include corruption, structural economic and social problems, and strong competition within certain sectors. |
||||||||||||||||||||||||||||
| T. Rowe Price Latin America 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 Latin America 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 Latin America 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 Latin America 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 Latin America 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 Latin America Fund | Growth investing | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Growth investing: The fund’s growth approach to investing could cause it to underperform other stock funds that employ a different investment style. Growth stocks tend to be more volatile than certain other types of stocks and their prices may fluctuate more dramatically than the overall stock market. A stock with growth characteristics can have sharp price declines due to decreases in current or expected earnings and may lack dividends that can help cushion its share price in a declining market. |
||||||||||||||||||||||||||||
| T. Rowe Price Latin America 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 Latin America Fund | Convertible securities and preferred stocks | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Convertible securities and preferred stocks: Convertible securities and preferred stocks carry credit and interest rate risk, along with other risks associated with both equity and fixed income securities, and convertible securities may be called back by the issuer prior to maturity at a price that is disadvantageous to the fund. |
||||||||||||||||||||||||||||
| T. Rowe Price Latin America 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. |
