Manzhouli is a sub-prefectural city located in Hulunbuir prefecture-level city, Inner Mongolia Autonomous Region, China. In ancient times the area was inhabited by the Donghu, Xiongnu, Xianbei, Khitan, Jurchen, Mongols and Manchu. During the decline of China's last dynasty, the Russian Empire forced the Qing (1644–1912) to cede the Outer Manchurian territory in the 1858 Treaty of Aigun. That treaty effectively made the Argun River, which originates in this area, the border between China and Russia. In 1901, the China Far East Railway was completed in accordance with the Sino-Russian Secret Treaty of 1896, linking Siberia, northeast China ("(Inner) Manchuria"), and the Russian Far East. A settlement then formed around Manchzhuriya Station, the first stop within Manchuria for Russians. It was the beginning of the modern city of Manzhouli and the name of Manzhouli came from Russian Манжули (Manzhuli). In 1905, Manzhouli was designated a trading center, greatly boosting Manzhouli's growth. In 1908 the Manzhouli customs was set up. Under the Republic of China, Manzhouli (under the name Lubin/臚濱) came under the jurisdiction of the province of Hsingan. In 1927, Manzhouli was designated as a city. Although with Hsingan and surrounding areas, Manzhouli came under Japanese control in 1931, and was part of the Empire of Manchuria from 1932 to 1945. The Russian townlet of Zabaykalsk is situated immediately north of Abagaitu Islet and Manzhouli.
