Using recently declassified Soviet documents, Jamil Hasanli examines Soviet involvement in the anti-China rebellion in East Turkistan. Hasanli takes readers back to the early 1930s when the Turkic national movement was suppressed by the Soviet government and the USSR. Hasanli deftly illustrates how Stalin's policies toward the movement changed after the turning point of World War II and the treachery of Sheng Shicai, leading up to the 1944 establishment of the Eastern Turkistan Republic and the start of the Cold War.
