China classifies various Mongolic groups, such as the Buryats and Oirats, together with the Inner Mongols under a single category of "Mongol." The Chinese government also classifies the Tuvans as Mongols, despite Tuvans being a Turkic, non-Mongolic ethnic group. The official language used for all of these Mongols in China is a literary standard based on the Chahar dialect of Mongol.

The ethnic classification might be inaccurate due to lack of information regarding the registering policy.
