Chechens
In 1989, 73.4% spoke Russian, though this figure has declined due to the wars for a large number of reasons (including the lack of proper education, the refusal to learn the language, and the mass dispersal of the Chechen diaspora due to the war). Chechens in the diaspora often speak the language of the country they live in (English, German, Arabic, Polish, Georgian, etc.).
Kazakhs
Kazakh is a state (official) language in Kazakhstan. It is also spoken in the Ili region of the Xinjiang Uyghur Autonomous Region in the People's Republic of China, where the Arabic script is used, and in western parts of Mongolia (Bayan-Ölgii and Khovd province), where Cyrillic script is in use. European Kazakhs use the Latin alphabet.
