Приамурье
During the nineteenth century, China became increasingly exposed to Western influence, and Shandong, a coastal province, was significantly affected. Qingdao was leased to Germany in 1897 and Weihai to Britain in 1898. As a result of foreign pressure from the Russian Empire, which had annexed Outer Manchuria by 1860, the Qing dynasty encouraged settlement of Shandong people to what remained of northeast China.
