China emerged as one of the world’s earliest civilizations in the fertile basin of the Yellow River in the North China Plain. For millennia, China’s political system was based on hereditary monarchies, or dynasties, beginning with the semi-legendary Xia dynasty. Since then, China has expanded, fractured, and re-unified numerous times. In 1912, the Republic of China (ROC) replaced the last dynasty and ruled the Chinese mainland until 1949, when it was defeated by the communist People’s Liberation Army in the Chinese Civil War. The Communist Party established the People’s Republic of China in Beijing on 1 October 1949, while the ROC government retreated to Taiwan with its present de facto capital in Taipei. Both the ROC and PRC continue to claim to be the legitimate government of all China, though the latter has more recognition in the world and controls more territory.

Since the introduction of economic reforms in 1978, China’s economy has been one of the world’s fastest-growing. As of 2016, it is the world’s second-largest economy by nominal GDP and largest by purchasing power parity (PPP). China is also the world’s largest exporter and second-largest importer of goods. China is a recognized nuclear weapons state and has the world’s largest standing army and second-largest defense budget. The PRC is a member of the United Nations, as it replaced the ROC as a permanent member of the U.N. Security Council in 1971. China is also a member of numerous formal and informal multilateral organizations, including the WTO, APEC, BRICS, the Shanghai Cooperation Organization (SCO), the BCIM and the G20.

The People’s Republic of China is divided into 22 provinces, five autonomous regions, each with a designated minority group; four municipalities; and two Special Administrative Regions (SARs) which enjoy a degree of political autonomy. These 31 provincial-level divisions can be collectively referred to as “mainland China”, a term which usually excludes two SARs of Hong Kong and Macau. Geographically, all 31 provincial divisions can be grouped into six regions, including North China, Northeast China, East China, South Central China, Southwest China and Northwest China.
