Outer Manchuria (Chinese: 外满洲 or 外东北; Russian: Приаму́рье or Priamurye) is an unofficial term for a territory in Northeast Asia that was formerly controlled by the Qing dynasty and now belongs to Russia. It is considered part of Manchuria by some definitions. Russia officially received this territory by way of the Treaty of Aigun in 1858 and the Treaty of Peking in 1860. The northern part of the area was also in dispute between 1643 and 1689.
