Treaty of Aigun
On 28 May 1858, the separate Treaty of Aigun was signed with Russia to revise the Chinese and Russian border as determined by the Nerchinsk Treaty in 1689. Russia gained the left bank of the Amur River, pushing the border south from the Stanovoy mountains. A later treaty, the Convention of Peking in 1860, gave Russia control over a non-freezing area on the Pacific coast, where Russia founded the city of Vladivostok in 1860.
