China, officially the People's Republic of China (PRC), consists of Chinese mainland, Hong Kong Special Administrative Region, Macau Special Administrative Region and Taiwan Province. It is the world's most populous country, with a population of over 1.3 billion. Covering approximately 9.6 million square kilometres(3,700,000 sq mi), it is the second-largest country in the world by land area after Russia and is either the third- or fourth-largest by total area, after Russia, Canada and, depending on the definition of total area, the United States. As of 2012, China has the world's second-largest economy in terms of nominal GDP, totalling approximately US$7.298 trillion according to the International Monetary Fund (IMF).

The territory of China lies between latitudes 18° and 54° N, and longitudes 73° and 135° E. Its landscape is vast and diverse, with forest steppes and the Gobi and Taklamakan deserts occupying the arid north and northwest near Mongolia and Central Asia, and subtropical forests being prevalent in the wetter south near Southeast Asia. The terrain of western China is rugged and elevated, with the Himalaya, Karakoram, Pamir and Tian Shan mountain ranges separating China from South and Central Asia. The Yangtze and Yellow Rivers, the third- and sixth-longest in the world, have their sources in the Tibetan Plateau and continue to the densely populated eastern seaboard. According to the National Bureau of Statistics of China, China's coastline is 32,000 kilometres (9,000 mi) long, including mainland shore 18,000 km and islands shore 14,000km.

China's climate is mainly dominated by dry seasons and wet monsoons, which lead to a pronounced temperature differences between winter and summer. It hosts a variety of forest types. Cold coniferous forests predominate in the north of the country. Subtropical forests dominate central and southern China. Tropical and seasonal rainforests, though confined to Yunnan and Hainan Island, contain a quarter of all the plant and animal species found in China.

In recent decades, China has suffered from severe environmental deterioration and pollution. A major environmental issue in China is the continued expansion of its deserts, particularly the Gobi Desert, which is currently the world's fifth-largest desert. Water quality, erosion, and pollution control have become important issues in China's relations with other countries. Melting glaciers in the Himalayas could potentially lead to water shortages for hundreds of millions of people.

Environmental campaigners have warned of the danger that water pollution poses 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 have been polluted by industrial and agricultural waste as of late 2011. This crisis is compounded by the perennial problem of water shortages, with 400 out of 600 surveyed Chinese cities reportedly short of drinking water. Additionally, numerous major Chinese coastal cities, including Shanghai, are deemed to be highly vulnerable to large-scale flooding.
