Taiwan in the context of Taiwania (supercomputer)

A country is an area of land, which has its own government and laws, or used to have them, such as a state, a nation, a nation state, or other political entity. When referring to a specific polity, the term "country" may refer to a sovereign state, a state with limited recognition, a constituent country, or a dependent territory. Most sovereign states, but not all countries, are members of the United Nations.

There is no universal agreement on the number of "countries" in the world with a range between 193 to 237. This ambiguity is a result of several states having disputed sovereignty status or limited recognition, and a number of non-sovereign entities are commonly considered countries. The definition and usage of the word "country" has fluctuated and changed over time. The Economist wrote in 2010 that "any attempt to find a clear definition of a country soon runs into a thicket of exceptions and anomalies."

An island country, island state, or island nation is a country whose primary territory consists of one or more islands or parts of islands. Approximately 25% of all independent countries are island countries. Island countries are historically more stable than many continental states but are vulnerable to conquest by naval superpowers. Indonesia is the largest and most populated island country in the world (and the fourth most populated country overall).

There are great variations between island country economies: they may rely mainly on extractive industries, such as mining, fishing and agriculture, and/or on services such as transit hubs, tourism, and financial services. Many islands have low-lying geographies and their economies and population centers develop along coast plains and ports; such states may be vulnerable to the effects of climate change, especially sea level rise.

East Asia is a geocultural region of Asia. It includes China, Japan, Mongolia, North Korea, South Korea, and Taiwan, plus two special administrative regions of China, Hong Kong and Macau. The economies of China, Japan, South Korea, and Taiwan are among the world's largest and most prosperous. East Asia borders North Asia to the north, Southeast Asia to the south, South Asia to the southwest, and Central Asia to the west. To its east is the Pacific Ocean.

East Asia, especially Chinese civilization, is regarded as one of the earliest cradles of civilization. Other ancient civilizations in East Asia that still exist as independent countries in the present day include the Japanese, Korean, and Mongolian civilizations. Various other civilizations existed as independent polities in East Asia in the past but have since been absorbed into neighbouring civilizations in the present day, such as Tibet, Manchuria, and Ryukyu (Okinawa), among many others. Taiwan has a relatively young history in the region after the prehistoric era; originally, it was a major site of Austronesian civilisation prior to colonisation by European colonial powers and China from the 17th century onward. For thousands of years, China was the leading civilization in the region, exerting influence on its neighbours. Historically, societies in East Asia have fallen within the Chinese sphere of influence, and East Asian vocabularies and scripts are often derived from Classical Chinese and Chinese script. The Chinese calendar serves as the root from which many other East Asian calendars are derived.

Chinese characters are logographs used to write the Chinese languages and others from regions historically influenced by Chinese culture. Of the four independently invented writing systems accepted by scholars, they represent the only one that has remained in continuous use. Over a documented history spanning more than three millennia, the function, style, and means of writing characters have changed greatly. Unlike letters in alphabets that reflect the sounds of speech, Chinese characters generally represent morphemes, the units of meaning in a language. Writing all of the frequently used vocabulary in a language requires roughly 2000–3000 characters; as of 2025, more than 100000 have been identified and included in The Unicode Standard. Characters are created according to several principles, where aspects of shape and pronunciation may be used to indicate the character's meaning.

The first attested characters are oracle bone inscriptions made during the 13th century BCE in what is now Anyang, Henan, as part of divinations conducted by the Shang dynasty royal house. Character forms were originally ideographic or pictographic in style, but evolved as writing spread across China. Numerous attempts have been made to reform the script, including the promotion of small seal script by the Qin dynasty (221–206 BCE). Clerical script, which had matured by the early Han dynasty (202 BCE – 220 CE), abstracted the forms of characters—obscuring their pictographic origins in favour of making them easier to write. Following the Han, regular script emerged as the result of cursive influence on clerical script, and has been the primary style used for characters since. Informed by a long tradition of lexicography, states using Chinese characters have standardized their forms—broadly, simplified characters are used to write Chinese in mainland China, Singapore, and Malaysia, while traditional characters are used in Taiwan, Hong Kong, and Macau.

New Spain, officially the Viceroyalty of New Spain (Spanish: Virreinato de Nueva España [birejˈnato ðe ˈnweβa esˈpaɲa] ; Nahuatl: Yankwik Kaxtillan Birreiyotl), originally the Kingdom of New Spain, was an integral territorial entity of the Spanish Empire, established by Habsburg Spain. It was one of several domains established during the Spanish conquest of the Americas, and had its capital in Mexico City. Its jurisdiction comprised a large area of the southern and western portions of North America, mainly what became Mexico and the Southwestern United States, but also California, Florida and Louisiana; Central America (as part of Mexico); the Caribbean like Hispaniola and Martinique, and northern parts of South America, even Colombia; several Pacific archipelagos, including the Philippines and Guam. Additional Asian colonies included "Spanish Formosa", on the island of Taiwan.

After the 1521 Spanish conquest of the Aztec Empire, conqueror Hernán Cortés named the territory New Spain, and established the new capital, Mexico City, on the site of Tenochtitlan, the capital of the Aztec Empire. Central Mexico became the base of expeditions of exploration and conquest, expanding the territory claimed by the Spanish Empire. With the political and economic importance of the conquest, the crown asserted direct control over the densely populated realm. The crown established New Spain as a viceroyalty in 1535, appointing as viceroy Antonio de Mendoza, an aristocrat loyal to the monarch rather than the conqueror Cortés. New Spain was the first of the viceroyalties that Spain created, the second being Peru in 1542, following the Spanish conquest of the Inca Empire. Both New Spain and Peru had dense indigenous populations at conquest as a source of labor and material wealth in the form of vast silver deposits, discovered and exploited beginning in the mid-1600s.

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.

Okinawa Island (Japanese: 沖縄島, Hepburn: Okinawa-jima; Okinawan: 沖縄 / うちなー, romanized: Uchinā; Kunigami: ふちなー, romanized: Fuchináa), also known as Okinawa Main Island (沖縄本島, Okinawa-hontō), is the largest of the Okinawa Islands and the Ryukyu (Nansei) Islands of Japan in the Kyushu region. It is the smallest and least populated of the five main islands of Japan. The island is approximately 106 kilometres (66 mi) long, an average 11 kilometres (7 mi) wide, and has an area of 1,206.98 square kilometers (466.02 sq mi). It is roughly 640 kilometres (350 nmi; 400 mi) south of the main island of Kyushu and the rest of Japan. It is 500 km (270 nmi; 310 mi) northeast of Taiwan. The total population of Okinawa Island was 1,384,762 in 2009. The greater Naha area has roughly 800,000 residents, while the city itself has about 320,000 people. Naha is the seat of Okinawa Prefecture on the southwestern part of Okinawa Island. Okinawa has a humid subtropical climate.

Okinawa has been a strategic location for the United States Armed Forces since the Battle of Okinawa and the end of World War II. The island was formally controlled by the United States Civil Administration of the Ryukyu Islands until 1972, with around 26,000 U.S. military personnel stationed on Okinawa today, comprising about half of the total complement of the United States Forces Japan, spread among 31 areas, across 13 bases and 48 training sites. United States military installations cover approximately 25% of the island and have been a point of contention among locals. Crimes committed by US military personnel, notably the 1995 Okinawa rape incident, have caused protests against the US military presence in Okinawa.

The Austronesian people, sometimes referred to as Austronesian-speaking peoples, are a large group of peoples who have settled in Taiwan, maritime Southeast Asia, parts of mainland Southeast Asia, Micronesia, coastal New Guinea, Island Melanesia, Polynesia, and Madagascar that speak Austronesian languages. They also include indigenous ethnic minorities in Vietnam, Cambodia, Myanmar, Thailand, Hainan, the Comoros, and the Torres Strait Islands. The nations and territories predominantly populated by Austronesian-speaking peoples are sometimes known collectively as Austronesia.

The group originated from a prehistoric seaborne migration, known as the Austronesian expansion, from Taiwan, circa 3000 to 1500 BCE. Austronesians reached the Batanes Islands in the northernmost Philippines by around 2200 BCE. They used sails some time before 2000 BCE. In conjunction with their use of other maritime technologies (notably catamarans, outrigger boats, lashed-lug boats, and the crab claw sail), this enabled phases of rapid dispersal into the islands of the Indo-Pacific, culminating in the settlement of New Zealand c. 1250 CE. During the initial part of the migrations, they encountered and assimilated (or were assimilated by) the Paleolithic populations that had migrated earlier into Maritime Southeast Asia and New Guinea. They reached as far as Easter Island to the east, Madagascar to the west, and New Zealand to the south. At the furthest extent, they might have also reached the Americas.

Simplified Chinese characters are one of two standardized character sets widely used to write the Chinese language, with the other being traditional characters. Their mass standardization during the 20th century was part of an initiative by the People's Republic of China (PRC) to promote literacy, and their use in ordinary circumstances on the mainland has been encouraged by the Chinese government since the 1950s. They are the standard forms used in mainland China, Malaysia, and Singapore, while traditional characters are officially used in Hong Kong, Macau, and Taiwan.

Simplification of a component—either a character or a sub-component called a radical—usually involves either a reduction in its total number of strokes, or an apparent streamlining of which strokes are chosen in what places—for example, the ⼓ 'WRAP' radical used in the traditional character 沒 is simplified to ⼏ 'TABLE' to form the simplified character 没. By systematically simplifying radicals, large swaths of the character set are altered. Some simplifications were based on popular cursive forms that embody graphic or phonetic simplifications of the traditional forms. In addition, variant characters with identical pronunciation and meaning were reduced to a single standardized character, usually the simplest among all variants in form. Finally, many characters were left untouched by simplification and are thus identical between the traditional and simplified Chinese orthographies.

Traditional Chinese characters are a standard set of Chinese character forms used to write Chinese languages. In Taiwan, the set of traditional characters is regulated by the Ministry of Education and standardized in the Standard Form of National Characters. These forms were predominant in written Chinese until the middle of the 20th century, when various countries that use Chinese characters began standardizing simplified sets of characters, often with characters that existed before as well-known variants of the predominant forms.

Simplified characters as codified by the People's Republic of China are predominantly used in mainland China, Malaysia, and Singapore. "Traditional" as such is a retronym applied to non-simplified character sets in the wake of widespread use of simplified characters. Traditional characters are commonly used in Taiwan, Hong Kong, and Macau, as well as in most overseas Chinese communities outside of Southeast Asia. As for non-Chinese languages written using Chinese characters, Japanese kanji include many simplified characters known as shinjitai standardized after World War II, sometimes distinct from their simplified Chinese counterparts. Korean hanja, still used to a certain extent in South Korea, remain virtually identical to traditional characters, with variations between the two forms largely stylistic.

"Mainland China" is a geopolitical term defined as the territory under direct administration of the People's Republic of China (PRC) in the aftermath of the Chinese Civil War. In addition to the geographical mainland, the geopolitical sense of the term includes islands such as Hainan, Chongming, and Zhoushan. It is also important to note that the terms "the Chinese mainland" or "the mainland of China" are preferred by explicitly pro-Beijing bodies, while the more common term in the English-speaking world and in Taiwan, Hong Kong, and Macau is "mainland China".

By convention, territories covered by the term exclude:

The Philippine Sea is a marginal sea of the Western Pacific Ocean east of the Philippine Archipelago and the largest sea in the world, occupying an estimated surface area of 5 million square kilometers (2×10^ sq mi). The Philippine Sea Plate forms the floor of the sea. Its western border is the first island chain to the west, comprising the Ryukyu Islands in the northwest and Taiwan in the west. Its southwestern border comprises the Philippine islands of Luzon, Catanduanes, Samar, Leyte, and Mindanao. Its northern border comprises the Japanese islands of Honshu, Shikoku and Kyūshū. Its eastern border is the second island chain to the east, comprising the Bonin Islands and Iwo Jima in the northeast, the Mariana Islands (including Guam, Saipan, and Tinian) in the due east, and Halmahera, Palau, Yap and Ulithi (of the Caroline Islands) in the southeast. Its southern border is Indonesia's Morotai Island.

The sea has a complex and diverse undersea relief. The floor is formed into a structural basin by a series of geologic faults and fracture zones. Island arcs, which are actually extended ridges protruding above the ocean surface due to plate tectonic activity in the area, enclose the Philippine Sea to the north, east and south. The Philippine archipelago, Ryukyu Islands, and the Marianas are examples. Another prominent feature of the Philippine Sea is the presence of deep sea trenches, among them the Philippine Trench and the Mariana Trench, containing the deepest point on the planet.

An island is a landmass (smaller than a continent) that is surrounded by water. Many island countries are spread over an archipelago, as is the case with Indonesia, Japan, and the Philippines—these countries consist of thousands of islands. Others consist of a single island, such as Barbados, Dominica, and Nauru; a main island and some smaller islands, such as Cuba, Iceland, and Sri Lanka; a part of an island, such as Brunei, the Dominican Republic, East Timor, and the Republic of Ireland; or one main island but also sharing borders in other islands, such as the United Kingdom (Great Britain and a part of Ireland).

The list also includes two states in free association with New Zealand, the Cook Islands and Niue, as well as two states with limited diplomatic recognition which have de facto control over territories entirely on the islands, Northern Cyprus and Taiwan. In total, 50 island countries have been included in the lists.

Taiwan, officially the Republic of China (ROC), is a country in East Asia. The island of Taiwan, formerly known to Westerners as Formosa, has an area of 35,808 square kilometres (13,826 sq mi) and makes up 99% of the land under ROC control. It lies about 180 kilometres (112 mi) across the Taiwan Strait from the southeastern coast of the Mainland China. The East China Sea is to the north of the island, the Philippine Sea to its east, the Luzon Strait directly to its south, and the South China Sea to its southwest. The ROC also controls a number of smaller islands, including the Penghu archipelago in the Taiwan Strait, Kinmen and Matsu in Fuchien near the Mainland coast, as well as Pratas and Taiping in the South China Sea.

Geologically, the main island comprises a tilted fault block, characterized by the contrast between the eastern two-thirds, consisting mostly of five rugged mountain ranges running parallel to the east coast, and the flat to gently rolling plains of the western third, where the majority of the population resides. Several peaks exceed 3,500 m in height – the highest, Yu Shan at 3,952 m (12,966 ft), makes Taiwan the world's fourth-highest island. The tectonic boundary that formed these ranges remains active, and the island experiences many earthquakes, some of them highly destructive. There are also many active submarine volcanoes in the Taiwan Straits.

The Philippines, officially known as the Republic of the Philippines, is an archipelagic country in Southeast Asia. Located in the western Pacific Ocean, it consists of 7,641 islands, with a total area of roughly 300,000 square kilometers, which are broadly categorized in three main geographical divisions from north to south: Luzon, Visayas, and Mindanao. With a population of over 112 million, it is the world's fourteenth-most-populous country.

The Philippines is bounded by the South China Sea to the west, the Philippine Sea to the east, and the Celebes Sea to the south. It shares maritime borders with Taiwan to the north, Japan and the Korean Peninsula to the northeast, Palau to the east and southeast, Indonesia to the south, Malaysia to the southwest, Vietnam to the west, and China to the northwest. It has diverse ethnicities and a rich culture. Manila is the country's capital, and its most populated city is Quezon City. Both are within Metro Manila.

The islands comprising the Taiwan Area under the jurisdiction of the Republic of China (ROC) are classified into various island groups. The island of Taiwan, also known as Formosa, is the largest island and the main component of the ROC-controlled territories. Islands that are claimed by the ROC but not administered, including those administered by the People's Republic of China (PRC), and those disputed with other countries such as the Tiaoyutai Islands (Senkaku Islands) and most of the South China Sea Islands, are excluded from this list.

At the adoption of Additional Articles of the Constitution of the Republic of China in the 1990s, these islands collectively form the "Free area of the Republic of China" or known alternatively as "Taiwan Area", which legally defines the territorial extent under the actual control of the ROC government.

Taipei (/ˌtaɪˈpeɪ/ ; traditional Chinese: 臺北; simplified Chinese: 台北; pinyin: Táiběi pronounced:[tʰǎɪpèɪ]), officially Taipei City, is the capital and a special municipality of Taiwan. Located in Northern Taiwan, Taipei City is an enclave of the municipality of New Taipei City that sits about 25 km (16 mi) southwest of the northern port city of Keelung. Most of the city rests on the Taipei Basin, an ancient lakebed. The basin is bounded by the relatively narrow valleys of the Keelung and Xindian rivers, which join to form the Tamsui River along the city's western border.

The municipality of Taipei is home to an estimated population of 2,494,813 (March 2023), forming the core part of the Taipei–Keelung metropolitan area, also known as "Greater Taipei", which includes the nearby cities of New Taipei and Keelung with a population of 7,047,559, the 40th most-populous urban area in the world—roughly one-third of Taiwanese citizens live in the metro areas. The name "Taipei" can refer either to the whole metropolitan area or just the municipality alone. Taipei has been the political center of the island since 1887, when it first became the seat of Taiwan Province by the Qing dynasty until 1895 and again from 1945 to 1956 by the Republic of China (ROC) government, with an interregnum from 1895 to 1945 as the seat of the Government-General of Taiwan during the Japanese rule. The city has been the national seat of the ROC central government since 1949, and it became the nation's first special municipality (then known as Yuan-controlled municipality) on 1 July 1967, upgrading from provincial city status.
