Internally, it has four neighbor provinces in China: Xinjiang Uygur Autonomous Region and Qinghai province to its north, Sichuan province to its east and Yunnan province to its southeast. Externally, Tibet borders on Burma, India, the Kingdom of Bhutan and Nepal from its south to west. Tibet covers an area of around 1.22 million km2, which accounts for 12.8% of the total of China. It is divided into six prefectures: Ngari Prefecture, Nagqu Prefecture, Shigatse Prefecture, Lhokha Prefecture, Nyingchi Prefecture and Chamdo Prefecture. And Tibet is divided into three parts according to its topography: the west (known as the North-Tibet Plateau), the south (featured by valleys) and the east (mainly canyons and is marked by a gradual decline in altitude intercepted by small ranges called Henduan Ranges).
