| 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 45.6% 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 bonds that are rated below investment grade. 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 seeks to invest in a diversified portfolio of high yield bonds, also known as “junk” bonds, and other high income producing instruments (such as bank loans). Junk bonds are bonds that are rated below investment grade (BB and lower, or an equivalent rating) by credit rating agencies or, if unrated, deemed to be below investment grade by T. Rowe Price. There is no limit on the fund’s holdings that are rated below investment grade. The fund may invest in a variety of debt instruments issued by U.S. and foreign corporations, U.S. and foreign governments and agencies, and supranational organizations, as well as bank loans, which represent amounts borrowed by companies from banks and other lenders. The fund normally invests at least 40% of its net assets in foreign securities, including securities of issuers in emerging markets. However, the amount invested in foreign securities will vary based on market conditions and there is no maximum amount that the fund may invest in securities of foreign issuers, including issuers in emerging markets. For purposes of determining whether a fund holding is a foreign security, the fund uses the country assigned to a security by Bloomberg or another third-party data provider. Junk bonds tend to provide high income in an effort to compensate investors for their higher risk of default, which is the failure to make required interest or principal payments, and should be considered speculative. High yield bond issuers often include small or relatively new companies lacking the history or capital to merit investment-grade status, former blue chip companies downgraded because of financial problems, companies electing to borrow heavily to finance or avoid a takeover or buyout, and firms with heavy debt loads. While high yield corporate bonds are typically issued with a fixed interest rate, bank loans usually have floating interest rates that reset periodically (typically quarterly or monthly). With bank loans, the borrowing companies tend to have significantly more debt than equity. The loans may or may not be secured by collateral and are often issued in connection with recapitalizations, acquisitions, leveraged buyouts, or refinancings. The bank loans in which the fund invests may be acquired directly from a lender or through the agent, as an assignment from another lender who holds the loans, or as a participation interest in another lender’s pool of loans. The fund may invest up to 20% of its total assets in bank loans. The fund may invest in holdings of any maturity and does not attempt to maintain any particular weighted average maturity or duration. While most assets are typically invested in bonds and other income producing instruments, the fund also uses derivatives in keeping with the fund’s objective. The fund may use a variety of derivatives, such as futures, forwards, and swaps for a number of purposes such as for exposure or hedging. Specifically, the fund uses forward currency exchange contracts. Forward currency exchange contracts are primarily used to protect the fund’s foreign bond holdings from adverse currency movements relative to the U.S. dollar. Forward currency exchange contracts are primarily used to protect the fund’s foreign bond holdings from adverse currency movements by hedging the fund’s foreign currency exposure back to the U.S. dollar. |

| 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 Global High Income Bond Fund | Fixed income markets | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Fixed income markets: Economic and other market developments can adversely affect the fixed income securities markets. At times, participants in these markets may develop concerns about the ability of certain issuers of debt instruments to make timely principal and interest payments, or they may develop concerns about the ability of financial institutions that make markets in certain debt instruments to facilitate an orderly market. Those concerns could cause increased volatility and reduced liquidity in particular securities or in the overall fixed income markets and the related derivatives markets. A lack of liquidity or other adverse credit market conditions may hamper the fund’s ability to sell the debt instruments in which it invests or to find and purchase suitable debt instruments. |
||||||||||||||||||||||||||||
| T. Rowe Price Global High Income Bond Fund | Interest rates | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Interest rates: A rise in interest rates typically causes the price of a fixed rate debt instrument to fall and its yield to rise. Conversely, a decline in interest rates typically causes the price of a fixed rate debt instrument to rise and the yield to fall. The prices and yields of inflation-linked bonds are directly impacted by the rate of inflation as well as changes in interest rates. Generally, funds with longer weighted average maturities and durations carry greater interest rate risk. Changes in monetary policy made by central banks and/or governments are likely to affect the interest rates or yields of the securities in which the fund invests. |
||||||||||||||||||||||||||||
| T. Rowe Price Global High Income Bond 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 Global High Income Bond Fund | Junk investing | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Junk investing: Investments in bonds that are rated below investment grade, commonly referred to as junk bonds, and loans that are rated below investment grade, expose the fund to greater volatility and credit risk than investments in securities that are rated investment grade. As a result, bonds and loans rated below investment grade carry a higher risk of default and should be considered speculative. |
||||||||||||||||||||||||||||
| T. Rowe Price Global High Income Bond Fund | Credit quality | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Credit quality: An issuer of a debt instrument could suffer an adverse change in financial condition that results in a payment default (failure to make scheduled interest or principal payments), rating downgrade, or inability to meet a financial obligation. Securities that are rated below investment grade carry greater risk of default and should be considered speculative. |
||||||||||||||||||||||||||||
| T. Rowe Price Global High Income Bond Fund | Foreign investing | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Foreign investing: Non-U.S. securities tend to be more volatile and have lower overall liquidity and trading volume 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. Further, securities of non-U.S. issuers are subject to trading markets with potential governmental interference, varying regulatory, auditing, and accounting standards, and settlement and clearance practices that differ from those of U.S. issuers. Investment in non-U.S. securities also carries currency risk. Any attempts to hedge currency risk could be unsuccessful. Such investments may have higher transaction costs compared with U.S. markets. The fund’s overall foreign investing risk is increased to the extent it has exposure to emerging markets. |
||||||||||||||||||||||||||||
| T. Rowe Price Global High Income Bond 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 Global High Income Bond Fund | Bank loans | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Bank loans: Investments in bank loans expose the fund to additional risks beyond those normally associated with more traditional debt instruments. The fund’s ability to receive payments in connection with a loan depends primarily on the financial condition of the borrower and whether or not a loan is secured by collateral, although there is no assurance that the collateral securing a loan will be sufficient to satisfy the loan obligation. In addition, bank loans often have contractual restrictions on resale, which can delay the sale and adversely impact the sale price. Transactions involving bank loans may have significantly longer settlement periods than more traditional investments (settlement can take longer than 7 days) and often involve borrowers whose financial condition is troubled or highly leveraged, which increases the risk that the fund may not receive its proceeds in a timely manner or that the fund may incur losses in order to pay redemption proceeds to its shareholders. In addition, loans are not registered under the federal securities laws like stocks and bonds, so investors in loans have less protection against improper practices than investors in registered securities. |
||||||||||||||||||||||||||||
| T. Rowe Price Global High Income Bond Fund | Covenant lite loans | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Covenant lite loans: Because covenant lite loans contain few or no financial maintenance covenants, they may not include terms that permit the lender of the loan to monitor the borrower’s financial performance and, if certain criteria are breached, declare a default, which would allow the lender to restructure the loan or take other action intended to help mitigate losses. As a result, the fund could experience relatively greater difficulty or delays in enforcing its rights on its holdings of covenant lite loans than its holdings of loans or securities with financial maintenance covenants, which may result in losses, especially during a downturn in the credit cycle. |
||||||||||||||||||||||||||||
| T. Rowe Price Global High Income Bond Fund | Derivatives | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Derivatives: The use of derivatives exposes the fund to additional volatility and potential losses. A derivative involves risks different from, and possibly greater than, the risks associated with investing directly in the assets on which the derivative is based, including liquidity risk, valuation risk, correlation risk, market risk, interest rate risk, leverage risk, counterparty and credit risk, operational risk, management risk, legal risk, and regulatory risk. Derivatives can be highly volatile, illiquid, and difficult to value, and changes in the value of a derivative may not properly correlate with changes in the value of the underlying asset, reference rate, or index. The fund could be exposed to significant losses if it is unable to close a derivatives position due to the lack of a liquid secondary trading market. The prices of derivatives may move in unexpected ways, especially in abnormal market conditions. Certain derivatives are also subject to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations. The use of derivatives includes the risk of potential operational issues, such as settlement issues. Derivatives are exposed to legal risks, such as the legality or enforceability of a contract. The adviser may not be able to accurately predict the direction of prices, economic factors, or other associated risks which could cause loss in value or impair the fund’s efforts to reduce overall volatility. New regulations may make derivatives more costly, limit availability, or otherwise affect their value or performance. |
||||||||||||||||||||||||||||
| T. Rowe Price Global High Income Bond Fund | Liquidity | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Liquidity: The fund may not be able to meet requests to redeem shares issued by the fund without significant dilution of the remaining shareholders’ interests in the fund. In addition, the fund may not be able to sell a holding in a timely manner at a desired price. Reduced liquidity in the bond markets can result from a number of events, such as limited trading activity, reductions in bond inventory, and rapid or unexpected changes in interest rates. Markets with lower overall liquidity could lead to greater price volatility and limit the fund’s ability to sell a holding at a suitable price. |
||||||||||||||||||||||||||||
| T. Rowe Price Global High Income Bond 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 Global High Income Bond 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. |
