"하나의 중국" (One China) is a political principle asserting that there is only one sovereign state under the name China. This concept emphasizes that both Mainland China and Taiwan are part of a single China, despite their separate governments and political systems. The principle is central to the foreign policy of the People's Republic of China (PRC), which seeks to prevent any recognition of Taiwan as an independent nation. Many countries, including the United States, acknowledge the One China policy while maintaining unofficial relations with Taiwan.
