Xinjiang (Uyghur: شىنجاڭ, ULY: Shinjang; Mandarin pronunciation: [ɕíntɕjɑ́ŋ]; Chinese: 新疆; pinyin: Xīnjiāng; Wade–Giles: Hsin1-chiang1; Postal map spelling: Sinkiang) is an autonomous region (Xinjiang Uyghur Autonomous Region) of the People's Republic of China. It is the largest Chinese administrative division and spans over 1.6 million km2. Xinjiang borders Russia, Mongolia, Kazakhstan, Kyrgyzstan, Tajikistan, Afghanistan, Pakistan and India, has abundant oil reserves and is China's largest natural gas-producing region.
Xinjiang was previously known as Xiyu (西域) or Qurighar (غەربىي دىيار), meaning Western Region, under the Han Dynasty, which drove the Xiongnu empire out of the region in 60 BC. This was in an effort to secure the profitable Silk Road. The name "Xinjiang", which literally means "New Frontier" or "New Border", was given during the Qing Dynasty. It is home to a number of different ethnic groups including the Uyghur, Han, Kazakh, Hui, Kyrgyz and Mongol. There are over a dozen autonomous prefectures and counties for various minorities living in Xinjiang. Older English-language reference works often refer to the area as Chinese Turkestan, Sinkiang and East Turkestan. Xinjiang is divided into the Dzungarian Basin in the north and the Tarim Basin in the south by a mountain range. Only about 4.3% of Xinjiang's land area is fit for human habitation.
