Other languages
A few linguistic minorities in China belong to neither the Sino-Tibetan nor the Altaic language family. The Tajiks of westernmost Xinjiang are related to the people of Tajikistan, and their language belongs to the Iranian branch of the Indo-European family. The Kawa people of the border area adjacent to Myanmar (Burma) speak a tongue of the Mon-Khmer branch of the Austroasiatic family. Speakers of languages in the Tai family are concentrated in southern Yunnan, notably in two autonomous prefectures—one whose population is related most closely to the Thai of northern Thailand and another whose Tai speakers are related to the Shan people of Myanmar. The Li of Hainan Island form a separate group whose dialects are related to the Tai and Austronesian languages. They share with the Miao people a district in the southern part of the island. A significant number of Koreans are concentrated in an autonomous prefecture in eastern Jilin along the North Korean border.
