China (Traditional Chinese: 中國; Simplified Chinese: 中国; Hanyu Pinyin: Zhōngguó (help·info); Tongyong Pinyin: Jhongguó; Gwoyeu Romatzyh: Jonggwo) is a cultural region and ancient civilization in East Asia. As a result of the 1949 Chinese Civil War, China today is administratively divided into two states: the People's Republic of China (PRC) and the Republic of China (ROC). The PRC administers and governs the majority of China (mainland China, Hong Kong, and Macau), while the ROC administers the island groups of Taiwan, the Pescadores, Kinmen, Matsu, and the disputed islands of Pratas, and Taiping in the South China Sea. However, the People's Republic of China considers Taiwan a "renegade province" and does not recognize the Republic of China (Taiwan). In contrast, the Republic of China (Taiwan) administers themselves as an independent sovereign state and does not recognize the Beijing-based People's Republic of China.
The Hong Kong Special Administrative Region, commonly known as Hong Kong, is one of the two special administrative regions of the People's Republic of China (PRC), along with Macau. The territory lies on the eastern side of the Pearl River Delta, bordering Guangdong province in the north and facing the South China Sea in the east, west and south. Beginning as a trading port in the 19th century, Hong Kong has developed into one of the world's leading financial centres.
Hong Kong was a dependent territory of the United Kingdom from 1842 until the transfer of its sovereignty to the People's Republic of China in 1997. The Sino-British Joint Declaration and the Basic Law of Hong Kong stipulate that Hong Kong operate with a high degree of autonomy until at least 2047, fifty years after the transfer. Under the policy of "one country, two systems", the Central People's Government is responsible for the territory's defence and foreign affairs, while Hong Kong maintains its own legal system, police force, monetary system, customs policy, immigration policy, and delegates to international organisations and events.
