List of countries by GDP (PPP) in the context of "Japanese economy"

Japan has a highly developed mixed economy, often referred to as an East Asian model. According to the IMF forecast for 2025, it will be the fourth-largest economy in the world by nominal GDP and the fifth-largest by purchasing power parity (PPP) by the end of the year. It constituted 3.7% of the world's economy on a nominal basis in 2024. According to the same forecast, the country's nominal per capita GDP (PPP) will be $56,440 (2025). Due to a volatile currency exchange rate, Japan's nominal GDP as measured in American dollars fluctuates sharply.

A founding member of the G7 and an early member of the OECD, Japan was the first country in Asia to achieve developed country status. In 2024, Japan was the sixth-largest in the world as an importer and eight-largest as an exporter. The country also has the world's fourth-largest consumer market. Japan used to run a considerable trade surplus, but the decline of the manufacturing sector since the 1980s and increased fossil fuel imports after the Fukushima nuclear accident in 2011 have changed this trend in recent years. Being the world's largest creditor nation, Japan has a considerable net international investment surplus. The country has the world's second-largest foreign-exchange reserves, worth $1.4 trillion. Japan has the third-largest financial assets in the world, valued at $12 trillion, or 8.6% of the global GDP total as of 2020. Japan has a highly efficient and strong social security system, which comprises roughly 23.5% of GDP. The Tokyo Stock Exchange is the world's fourth-largest stock exchange by market capitalisation as of 2025.

Taiwan is a highly developed free-market economy. It is the 8th largest in Asia and 21st-largest in the world by purchasing power parity, allowing Taiwan to be included in the advanced economies group by the International Monetary Fund. Taiwan is notable for its rapid economic development from an agriculture-based society to an industrialized, high-income country. This economic growth has been described as the Taiwan Miracle. It is gauged in the high-income economies group by the World Bank. Taiwan is one of the leading producers of computer microchip and high-tech electronics.

Japan is a great power and a member of numerous international organizations, including the United Nations (since 1956), the OECD, and the Group of Seven. Although it has renounced its right to declare war, the country maintains Self-Defense Forces that rank as one of the world's strongest militaries. After World War II, Japan experienced record growth in an economic miracle, becoming the second-largest economy in the world by 1990. As of 2021, the country's economy is the third-largest by nominal GDP and the fourth-largest by PPP.

Japan has close economic and military relations with the United States, with which it maintains a security alliance. The United States is a major market for Japanese exports and a major source of Japanese imports, and is committed to defending the country, with military bases in Japan.

The economy of Romania is a developing mixed economy, with a high degree of complexity. It ranks 12th in the European Union by total nominal GDP and 7th largest when adjusted by purchasing power (PPP). The World Bank notes that Romania's efforts are focused on accelerating structural reforms and strengthening institutions in order to further converge with the European Union. The country's economic growth has been one of the highest in the EU since 2010, with 2022 seeing a better-than-expected 4.8% increase.

In recent years, it witnessed growth rates such as: 4.8% in 2016, 7.1% in 2017, 4.4% in 2018 and 4.1% in 2019. In 2024, its GDP per capita in purchasing power standards reached 78% of the European Union average, up from 44% in 2007, the highest growth rate in the EU27. Romania's economy ranks 35th in the world by its total GDP (PPP), with a Int$784 billion annual output (2023 est.).

The economy of Russia is a high-income, industrialized, mixed and market-oriented emerging economy. It has the ninth-largest economy in the world by nominal GDP and the fourth-largest economy by GDP (PPP). Due to a volatile currency exchange rate, its GDP measured in nominal terms fluctuates sharply. Russia was the last major economy to join the World Trade Organization (WTO), becoming a member in 2012.

Russia has large amounts of energy resources throughout its vast landmass, particularly natural gas and petroleum, which play a crucial role in its energy self-sufficiency and exports. The country has been widely described as an energy superpower; with it having the largest natural gas reserves in the world, the second-largest coal reserves, the eighth-largest oil reserves, and the largest oil shale reserves in Europe. Russia is the third-largest exporter of natural gas, the second-largest natural gas producer, the second-largest oil exporter and producer, and the third-largest coal exporter. As of 2020, its foreign exchange reserves were the fifth-largest in the world. Russia has a labour force of about 73 million people, which is the eighth-largest in the world. It is the third-largest exporter of arms in the world. The large oil and gas sector accounted up to 30% of Russia's federal budget revenues in 2024, down from 50% in the mid-2010s, suggesting economic diversification.

Mexico has a developing mixed economy. It is the 13th largest in the world in nominal GDP terms and by purchasing power parity as of 2024. Since the 1994 crisis, administrations have improved the country's macroeconomic fundamentals. Mexico was not significantly influenced by the 2002 South American crisis and maintained positive, although low, rates of growth after a brief period of stagnation in 2001. However, Mexico was one of the Latin American nations most affected by the 2008 recession, with its gross domestic product contracting by more than 6% that year. Mexico has the lowest social expenditure among OECD countries, roughly 7.5% of GDP.

The Mexican economy has maintained macroeconomic stability, reducing inflation and interest rates to record lows. Despite this, significant gaps persist between the urban and the rural population, the northern and southern states, and the rich and the poor. Some of the unresolved issues include the upgrade of infrastructure, the modernization of the tax system and labor laws, and the reduction of income inequality. Tax revenues, 19.6 percent of GDP in 2013, were the lowest among the 34 OECD countries. The main problems Mexico faces are poverty rates and regional inequalities remaining high. The lack of formal employment, low access to financial services, and corruption has limited productivity growth. The medium-term growth prospects were also affected by a lower proportion of women in the workforce, and low investment since 2015.

The People's Republic of China emerged as a great power and one of the three big players in the tri-polar geopolitics (PRC-US-USSR) during the Cold War, after the Korean War in 1950–1953 and the Sino-Soviet split in the 1960s, with its status as a recognized nuclear weapons state. Currently, China has one of the world's largest populations, second largest GDP (nominal) and the largest economy in the world by PPP.

In 1950–1953 it fought an undeclared war in Korea against the United States. Until the late 1950s it was allied with the Soviet Union but by 1960 they began a bitter contest for control over the local communist movement in many countries. It reached détente with the United States in 1972. After Chinese Communist Party chairman Mao Zedong died in 1976, Deng Xiaoping led a massive process of industrialization and emphasized trade relations with the world, while maintaining a low key, less ideological foreign policy, widely described by the phrase Taoguang Yanghui, or "hide one's talent and bide one's time". The Chinese economy grew very rapidly giving it steadily increasing power and ambition.

The United States has a highly developed diversified market-oriented mixed economy. It is the world's largest economy by nominal GDP and second largest by purchasing power parity (PPP). As of 2025, it has the world's ninth-highest nominal GDP per capita and eleventh-highest GDP per capita by PPP. According to the World Bank, the U.S. accounted for 14.8% of the global aggregate GDP in 2024 in purchasing power parity terms and 26.2% in nominal terms. The U.S. dollar is the currency most used in international transactions and the world's foremost reserve currency, backed by a large U.S. treasuries market, its role as the reference standard for the petrodollar system, and its linked eurodollar. Several countries use it as their official currency and in others it is the de facto currency. Since the end of World War II, the economy has achieved relatively steady growth, low unemployment and inflation, and rapid advances in technology.

The American economy is fueled by high productivity, well-developed transportation infrastructure, and extensive natural resources. Americans have the sixth highest average household and employee income among OECD member states. In 2021, they had the highest median household income among OECD countries, although the country also had one of the world's highest income inequalities among the developed countries. The largest U.S. trading partners are Mexico, Canada, China, Japan, Germany, South Korea, the United Kingdom, Taiwan, India, and Vietnam. The U.S. is the world's largest importer and second-largest exporter. It has free trade agreements with several countries, including Canada and Mexico (through the USMCA), Australia, South Korea, Israel, and several others that are in effect or under negotiation. The U.S. has a highly flexible labor market, where the industry adheres to a hire-and-fire policy, and job security is relatively low. Among OECD nations, the U.S. has a highly efficient social security system; social expenditure stood at roughly 30% of GDP.
