Found in 3 desert areas, spread across north China (Xinjiang province) and Mongolia. The whole population is only numbered at around 950. Interestingly, while closely related to the domestic dromedary camel, it is not the same species, with the 2 having split around 1 million years ago.

Currently, there are only around 950 wild Bactrian camels. The majority live on the Lop Nur Wild Camel National Nature Reserve in China, and a smaller population lives in the Great Gobi A Strictly Protected Area in Mongolia. 

Other smaller populations can be found in the Altun Shan Wild Camel Nature Reserve (1986) in Qakilik County, in the Aksai Annanba Nature Reserve (1992), and in Dunhuang Wanyaodun Nature Reserve (now Dunhuang Xihu Wild Camel Nature Reserve) contiguous with the reserve in Qakilik (2001) and a reserve in Mazongshan contiguous with the reserve in Mongolia, all in China.

This means there is much space available, but as yet the population has not started rebounding a great deal. The video below is from the original planet earth.
