This group, located mainly in China's western Xinjiang region is actually a collection of over a dozen small East Iranian ethnic groups that are related to, but distinct from, the Tajiks of Tajikistan.

In China, the Tajik language has no official written form. Most Chinese Tajik speakers speak the Sariqul (or Sariköli) dialect and use Uyghur and Chinese to communicate with people of other nationalities in the area.
