The monograph is devoted to the history of international relations in Central Asia in 1795-1856. On the basis of little-studied Chinese sources, it examines the relationship between the Qing (Manchurian) Empire (1644-1911) and the Dzungar (Oirat) Khanate (1695-1756) in East Turkestan, the reasons for its disappearance from the political arena and the tragic fate of the Oirat people.
