Hong Kong in the context of "Taiwan Miracle"

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.

In finance, an exchange rate is the rate at which one currency will be exchanged for another currency. Currencies are most commonly national currencies, but may be sub-national as in the case of Hong Kong or supra-national as in the case of the euro.

The exchange rate is also regarded as the value of one country's currency in relation to another currency. For example, an interbank exchange rate of 141 Japanese yen to the United States dollar means that ¥141 will be exchanged for US$1 or that US$1 will be exchanged for ¥141. In this case it is said that the price of a dollar in relation to yen is ¥141, or equivalently that the price of a yen in relation to dollars is $1/141.

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.

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:

Lady Justice (Latin: Iustitia) is an allegorical personification of the moral force in judicial systems. Her attributes are scales, a sword and sometimes a blindfold. She often appears as a pair with Prudentia.

Lady Justice originates from the personification of Justice in ancient Roman art known as Iustitia or Justitia, who is equivalent to the Greek goddess Themis.

An open border is a border that enables free movement of people and often of goods between jurisdictions with no restrictions on movement and is lacking a border control. A border may be an open border due to intentional legislation allowing free movement of people across the border (de jure), or a border may be an open border due to a lack of legal controls, a lack of adequate enforcement or adequate supervision of the border (de facto). An example of the former is the Schengen Agreement between most members of the European Economic Area (EFTA and the EU). An example of the latter has been the border between Bangladesh and India, which is becoming controlled. The term "open borders" applies only to the flow of people, not the flow of goods and services, and only to borders between political jurisdictions, not to mere boundaries of privately owned property.

Open borders are the norm for borders between subdivisions within the boundaries of sovereign states, though some countries do maintain internal border controls (for example between the People's Republic of China mainland and the special administrative regions of Hong Kong and Macau, between the United States and the unincorporated territories of Guam, the Northern Mariana Islands and American Samoa, and the Minor Outlying Islands, or between North Korea's provinces and cities). Open borders are also usual between member states of federations, though (very rarely) movement between member states may be controlled in exceptional circumstances. Federations, confederations and similar multi-national unions typically maintain external border controls through a collective border control system, though they sometimes have open borders with other non-member states through special international agreements – such as between Schengen Agreement countries as mentioned above.
