This group with a population of 41,028 (2000), is located mainly in China's western Xinjiang region with 60% living in Taxkorgan Tajik Autonomous County; some researchers view them as a collection of over a dozen small East Iranianethnic groups that are related to, but distinct from, the Tajiks of Tajikistan. The Ethnologue claims that they are actually Shugni and Wakhi.
In China, the languages of the Tajiks have no official written form. The great majority of Chinese Tajik speakers speak the Sariqul (or Sariköli) dialect and use Uyghur and Chinese to communicate with people of other nationalities in the area. A small proportion of Chinese Tajik speakers speak Wakhi.
