evidence: - Russia gained the left bank of the Amur River that had been assigned to China as a result of Treaty of Nerchinsk of 1689. (Chinese and Manchu residents of the Sixty-Four Villages East of the Heilongjiang River would be allowed to remain, under the jurisdiction of Manchu government.) The Amur, Sungari, and Ussuri rivers were to be open exclusively to both Chinese and Russian ships. The territory bounded on the west by the Ussuri, on the north by the Amur, and on the east and south by the Sea of Japan was to be jointly administered by Russia and China—a "condominium" arrangement similar to that which the British and Americans had agreed upon for the Oregon Territory in the Treaty of 1818.[2] (Russia gained sole control of this land two years later)[4] Counting also the loss of this land, China effectively lost more than one million square kilometers of territory.
