query: How many dialects are spoken by the Mongol?
passage: Mongolian language
The status of certain varieties in the Mongolic group—whether they are languages distinct from Mongolian or just dialects of it—is disputed. There are at least three such varieties: Oirat (including the Kalmyk variety) and Buryat, both of which are spoken in Russia, Mongolia, and China; and Ordos, spoken around Inner Mongolia's Ordos City.[17]
passage: Khalkha Mongols
The overwhelming majority of Khalkha Mongols now reside in the modern state of Mongolia. However, there are four small banners in China: two in Inner Mongolia; one in Qinghai; and one in Jehol. There are also several groups among the Buriats in Russia, however, they no longer retain the Khalkha self-identity, culture, and language. The Halh Mongols in Qinghai, China and the ones among the Buriats in Russia were subjects to Khalkha's Tsogtu Khan and his sons.
