World Bank high-income economy in the context of "Taiwan Miracle"

The Organisation for Economic Co-operation and Development (OECD; French: Organisation de coopération et de développement économiques, OCDE) is an intergovernmental organisation with 38 member countries, founded in 1961 to stimulate economic progress and world trade. It is a forum whose member countries describe themselves as committed to democracy and the market economy, providing a platform to compare policy experiences, seek answers to common problems, identify good practices, and coordinate domestic and international policies of its members.

The majority of OECD members are generally regarded as developed countries, with high-income economies, and a very high Human Development Index.

South Korea has a highly developed mixed economy. By nominal GDP, the economy was worth ₩2.61 quadrillion (US$1.87 trillion). It has the 4th largest economy in Asia and the 13th largest in the world as of 2025. South Korea is notable for its rapid economic development from an underdeveloped nation to a developed, high-income country in a few decades. This economic growth has been described as the Miracle on the Han River, which has allowed it to join the OECD and the G20. It is included in the group of Next Eleven countries as having the potential to play a dominant role in the global economy by the middle of the 21st century. Among OECD members, South Korea has a highly efficient and strong social security system; social expenditure stood at roughly 15.5% of GDP. South Korea spends around 4.93% of GDP on advanced research and development across various sectors of the economy.

South Korea's education system and the establishment of a motivated and educated populace were largely responsible for spurring the country's high technology boom and economic development. South Korea began to adapt an export-oriented economic strategy in the 1960s to fuel its economy. In 2022, South Korea was the ninth largest exporter and ninth largest importer in the world. The Bank of Korea and the Korea Development Institute periodically release major economic indicators and economic trends of the economy of South Korea.

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.

Belgium, officially the Kingdom of Belgium, is a country in Northwestern Europe. Situated in a coastal lowland region known as the Low Countries, it is bordered by the Netherlands to the north, Germany to the east, Luxembourg to the southeast, France to the south, and the North Sea to the west. Belgium covers an area of 30,689 km (11,849 sq mi) and has a population of more than 11.8 million; its population density of 383/km (990/sq mi) ranks 22nd in the world and sixth in Europe. The capital and largest metropolitan region is Brussels; other major cities are Antwerp, Ghent, Charleroi, Liège, Bruges, Namur, and Leuven.

Belgium is a parliamentary constitutional monarchy with a complex federal system structured on regional and linguistic grounds. The country is divided into three highly autonomous regions: the Flemish Region (Flanders) in the north, the Walloon Region (Wallonia) in the south, and the Brussels-Capital Region in the middle. Belgium is also home to two main linguistic communities: the Dutch-speaking Flemish Community, which constitutes about 60 percent of the population, and the French-speaking French Community, which constitutes about 40 percent of the population; a small German-speaking Community, comprising around one percent of the population, exists in the East Cantons. Belgium's linguistic diversity and related political conflicts are reflected in its complex system of governance, made up of six different governments. Belgium is a developed country with an advanced high-income economy. It is one of the six founding members of the European Union, with its capital of Brussels serving as the de facto capital of the EU, hosting the official seats of the European Commission, the Council of the European Union, the European Council, and one of two seats of the European Parliament (the other being Strasbourg). Brussels also hosts the headquarters of many major international organizations, such as NATO.

A developing country is a country with a less-developed industrial base and a lower Human Development Index (HDI) relative to developed countries. However, this definition is not universally agreed upon. There is also no clear agreement on which countries fit this category. The terms low-and middle-income country (LMIC) and newly emerging economy (NEE) are often used interchangeably but they refer only to the economy of the countries. The World Bank classifies the world's economies into four groups, based on gross national income per capita: high-, upper-middle-, lower-middle-, and low-income countries. Least developed countries, landlocked developing countries, and small island developing states are all sub-groupings of developing countries. Countries on the other end of the spectrum are usually referred to as high-income countries or developed countries.

There are controversies over the terms' use, as some feel that it perpetuates an outdated concept of "us" and "them". In 2015, the World Bank declared that the "developing/developed world categorization" had become less relevant and that they would phase out the use of that descriptor. Instead, their reports will present data aggregations for regions and income groups. The term "Global South" is used by some as an alternative term to developing countries.

The Baltic states or the Baltic countries is a geopolitical term encompassing Estonia, Latvia, and Lithuania. All three countries are members of NATO, the European Union, the Eurozone, and the OECD. The three sovereign states on the eastern coast of the Baltic Sea are sometimes referred to as the "Baltic nations", less often and in historical circumstances also as the "Baltic republics", the "Baltic lands", or simply the Baltics.

All three Baltic countries are classified as high-income economies by the World Bank and maintain a very high Human Development Index. The three governments engage in intergovernmental and parliamentary cooperation. There is also frequent cooperation in foreign and security policy, defence, energy, and transportation.

The Four Asian Tigers (a.k.a. the Four Asian Dragons or Four Little Dragons in Chinese and Korean) are the developed Asian economies of Hong Kong, Singapore, South Korea, and Taiwan. Between the early 1950s and 1990s, they underwent rapid industrialization and maintained exceptionally high growth rates of more than 7 percent a year.

By the early 21st century, these economies had developed into high-income economies, specializing in areas of competitive advantage. Hong Kong and Singapore have become leading international financial centres, whereas South Korea and Taiwan are leaders in manufacturing electronic components and devices; Taiwan now produces the most advanced semiconductor chips in the world; South Korea has also developed into a major global arms manufacturer. Large institutions have pushed to have them serve as role models for many developing countries, especially the Tiger Cub Economies of Southeast Asia.

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.
