China (中国; Zhōngguó), officially known as the People's Republic of China (中华人民共和国 Zhōnghuá Rénmín Gònghéguó) is a huge country in Eastern Asia (about the same size as the United States of America) with the world's largest population. With coasts on the East China Sea, Korea Bay, Yellow Sea, and South China Sea, in total it borders 14 nations. It borders Afghanistan, Pakistan (through the disputed territory of Kashmir), India, Nepal, Bhutan, Myanmar, Laos and Vietnam to the south; Tajikistan, Kazakhstan and Kyrgyzstan to the west; Russia and Mongolia to the north and North Korea to the east. This number of neighbouring states is equalled only by China's vast neighbour to the north, Russia. The roughly 5000-year old Chinese civilization has endured through millennia of tumultuous upheaval and revolutions, periods of golden ages and anarchy alike. Through the recent economic boom initiated by the reforms of Deng Xiaoping, China is once again one of the leading nations in the world, buoyed by its large, industrious population and abundant natural resources. The depth and complexity of the Chinese civilization, with its rich heritage, has fascinated Westerners such as Marco Polo and Gottfried Leibniz through the Great Silk Road and more ways of culture exchange in centuries past, and will continue to excite - and bewilder - the traveler today.
