Range
Afghanistan, Kazakhstan, Kyrgyzstan, Tajikistan and Turkmenistan per the general account; the Mammal Diversity Database also lists China
The Tian Shan vole is a rodent in the family Cricetidae. The general species account lists Afghanistan, Kazakhstan, Kyrgyzstan, Tajikistan and Turkmenistan, while the Mammal Diversity Database also lists Uzbekistan and China, so its status in China is unconfirmed here (Wikipedia, general species account).
