1991 Sino-Soviet Border Agreement
The 1991 Sino–Soviet Border Agreement was a treaty signed between China and the Soviet Union on May 16, 1991. It set up demarcation work to resolve most of the border disputes between the two states. Initially signed by China and the Soviet Union, the terms of the agreement were resumed by Russia after the dissolution of the Soviet Union. The treaty resulted in some minor territorial changes along the border.

Sino-Soviet border conflict
The Sino-Soviet border conflict was a seven-month undeclared military conflict between the Soviet Union and China in 1969, following the Sino-Soviet split. The most serious border clash, which brought the world's two largest communist states to the brink of war, occurred near Damansky (Zhenbao) Island on the Ussuri (Wusuli) River in Manchuria. Clashes also took place in Xinjiang.
