China, officially the People's Republic of China, is a sovereign state located in East Asia. It is the world's most populous country, with a population of over 1.35 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 – which is controlled by the Republic of China (ROC), a separate political entity – as its 23rd province, a claim controversial due to the complex political status of Taiwan and the unresolved Chinese Civil War.
Covering approximately 9.6 million square kilometres, China is the world's second-largest country by land
area, but only the third or fourth-largest by total area, dependent on whether the surface areas of various inland bodies of water such as the Great Lakes are included in the total area of a country. China's landscape is vast and diverse, ranging from forest steppes and the Gobi and Taklamakan deserts in the arid north to subtropical forests in the wetter south. The Himalaya, Karakoram, Pamir and Tian Shan mountain ranges separate China from South and Central Asia. The Yangtze and Yellow Rivers, the third- and sixth-longest in the world, run from the Tibetan Plateau to the densely populated eastern seaboard. China's coastline along the Pacific Ocean is 14,500 kilometres (9,000 mi) long, and is bounded by the Bohai, Yellow, East and South China Seas.
The ancient Chinese civilization – one of the world's earliest – flourished in the fertile basin of the Yellow River in the North China Plain. For millennia, China's political system was based on hereditary monarchies, known as dynasties, beginning with the semi-mythological Xia of the Yellow River basin (c. 2000 BCE). Since 221 BCE, when the Qin Dynasty first conquered several states to form a Chinese empire, the country has expanded, fractured and been reformed numerous times. The Republic of China overthrew the last dynasty in 1911, and ruled the Chinese mainland until 1949. After the defeat of the Empire of Japan in World War II, the Communist Party defeated the nationalist Kuomintang in mainland China and established the People's Republic of China in Beijing on 1 October 1949, while the Kuomintang relocated the ROC government to its present capital of Taipei.
Since the introduction of economic reforms in 1978, China has become the world's fastest-growing major economy. As of 2013, it is the world's second-largest economy by both nominal total GDP and purchasing power parity (PPP), and is also the world's largest exporter and importer of goods. China is a recognized nuclear weapons state and has the world's largest standing army, with the second-largest defense budget. The PRC has been a United Nations member since 1971, when it replaced the ROC as a permanent member of the U.N. Security Council. China is also a member of numerous formal and informal multilateral organizations, including the WTO, APEC, BRICS, the Shanghai Cooperation Organisation, the BCIM and the G-20. China is a regional power within Asia and has been characterized as a potential superpower by a number of academics, military analysts, and public policy and economics analysts.
In recent decades, China has suffered from severe environmental deterioration and pollution. While regulations such as the 1979 Environmental Protection Law are fairly stringent, they are poorly enforced, as they are frequently disregarded by local communities and government officials in favour of rapid economic development. Urban air pollution is a severe health issue in the country; the World Bank estimates that 16 of the world's most-polluted cities are located in China.
Environmental campaigners have warned that water pollution is becoming a severe threat to Chinese society. According to the Chinese Ministry of Water Resources, roughly 300 million Chinese do not have access to safe drinking water, and 40% of China's rivers had been polluted by industrial and agricultural waste by late 2011. This crisis is compounded by increasingly severe water shortages, particularly in the north-east of the country.
