Russia

In the 1650s, the Qing Empire engaged the Tsardom of Russia in a series of border conflicts along the Amur River region, which concluded with the Qing gaining control of the area after the Siege of Albazin.

The Russians invaded the northern frontier again in the 1680s. A series of battles and negotiations culminated in the Treaty of Nerchinsk of 1689, by which a border was agreed between Russia and China.
