Manzhouli (; Манжуур хот; ) is a sub-prefectural city located in Hulunbuir prefecture-level city, Inner Mongolia Autonomous Region, China. Located on the border with Russia, it is a major land port of entry. It has an area of and a population of almost 250,000 (in 2010).
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 Russian Manchuria in the 1858 Treaty of Aigun. That treaty 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, Manchuria/northeast China, 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 []) 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. It became part of Inner Mongolia under China from 1946.
In 1992, Manzhouli became one of the first land border cities opened up by the People's Republic of China. It has since experienced somewhat of a boom as a center of border trade between China and Russia. In 2017, the Manzhouli Stadium opened. The football stadium has a capacity of 20,153.
