The Treaty of Nerchinsk of 1689 (Russian: Нерчинский договор; ) was the first treaty between Russia and China. The Russians gave up the area north of the Amur River as far as the Stanovoy Mountains and kept the area between the Argun River and Lake Baikal. This border along the Argun River and Stanovoy Mountains lasted until the Amur Annexation in 1860. For background see History of Sino-Russian relations.
