China (i/Ã‹ÂˆtÃŠÂƒaÃ‰ÂªnÃ‰Â™/; Chinese: Ã¤Â¸ÂÃ¥Â›Â½; pinyin: ZhÃ…ÂngguÃƒÂ³), officially the People's Republic of China (PRC), is a sovereign state located in East Asia. It is the world's most populous country, with a population of over 1.35Â billion. The PRC is a single-party state governed by the Communist Party, with its seat of government in the capital city of Beijing. It exercises jurisdiction over 22 provinces, five autonomous regions, four direct-controlled municipalities (Beijing, Tianjin, Shanghai, and Chongqing), and two mostly self-governing special administrative regions (Hong Kong and Macau). The PRC also claims Taiwan Ã¢Â€Â“ which is controlled by the Republic of China (ROC), a separate political entity Ã¢Â€Â“ as its 23rd province, a claim controversial due to the complex political status of Taiwan and the unresolved Chinese Civil War.
