Hainan is the smallest and southernmost province of the People's Republic of China (PRC), consisting of various islands in the South China Sea. Hainan Island, separated from Guangdong's Leizhou Peninsula by the Qiongzhou Strait, is the largest and fifth most populous island under PRC control (Taiwan, which is slightly larger, is also claimed but not controlled by the PRC) and makes up the majority of the province.
The province has an area of 33,920 square kilometers (13,100 sq mi), with Hainan Island making up 32,900 square kilometers (12,700 sq mi) (97%) and the rest divided among 200 islands scattered across three archipelagos. It was administered as part of Guangdong until 1988, when it became a separate province; around the same time, it was made the largest Special Economic Zone established by Deng Xiaoping as part of the Chinese economic reform.
There are a total of ten major cities and ten counties in Hainan Province. Haikou on the northern coast of Hainan Island is the capital while Sanya is a well-known tourist destination on the southern coast. The other major cities are Wenchang, Qionghai, Wanning, Wuzhishan, Dongfang, and Danzhou.
According to China's territorial claims several territories in the South China Sea, including the Spratly Islands (Nansha) and Paracel Islands (Xisha), are notionally administered as part of the province.
