Located in the east of the Asian continent, on the western shore of the Pacific Ocean, the PRC has a land area of about 9.6 million sq km, and is the third-largest country in the world, next only to Russia and Canada.

From north to south, the territory of China spans over 49 latitudes, stretching from the center of the Heilong River north of the town of Mohe (latitude 53? 30’ N) to the Zengmu Reef at the southernmost tip of the Nansha Islands (latitude 4? N). From east to west, the nation extends over 60 longitudes from the confluence of the Heilong and Wusuli rivers (longitude 135? 05’ E) to the Pamirs (longitude 73? 40’E). China extends over 5,000 sq km both from north to south and from east to west.

With a land boundary of some 22,800 km, China is bordered by Korea to the east; Mongolia to the north; Russia to the northeast; Kazakhstan, Kyrgyzstan (Kirghizstan) and Tadzhikistan (Tajikistan) to the northwest; Afghanistan, Pakistan, India, Nepal, Sikkim and Bhutan to the west and southwest; and Myanmar, Laos and Vietnam to the south.

China’s mainland coastline measures approximately 18,000 km, with a flat topography, and many excellent docks and harbors, most of which are ice-free all year round. The Chinese mainland is flanked to the east and south by the Bohai, Yellow, East China and South China seas, with a total maritime area of 4.73 million sq km. The Bohai Sea is China’s continental sea, while the Yellow, East China and South China seas are marginal seas of the Pacific Ocean.

A total of 5,400 islands dot China’s territorial seas. The largest of these, with an area of about 36,000 sq km, is Taiwan, followed by Hainan with an area of 34,000 sq km. The Diaoyu and Chiwei islands, located to the northeast of Taiwan Island, are China’s easternmost islands. The many islands, islets, reefs and shoals in the South China Sea, known collectively as the South China Sea Islands, are the southernmost island group of China. They are called the Dongsha (East Sandbar), Xisha (West Sandbar), Zhongsha (Middle Sandbar) and Nansha (South Sandbar) island groups according to their geographical locations.
