Zuo Fengrong, an expert in Soviet history, examines trends in Chinese scholarship on the USSR’s collapse across the past thirty years. Zuo argues that while this literature advanced over time with the availability of newly declassified archival sources, it has stagnated more recently. As a prognosis, Zuo encourages renewed attention to the failure of Soviet socialism and the Communist Party of the Soviet Union’s (CPSU) loss of power, in order to extract lessons for China.
