During the Qing Dynasty the Nenjiang provided an important communication route between southern Manchuria and the cities of Qiqihar and Nenjiang County, Mergen, both of which served at various points as capitals of the Qing Heilongjiang. A portage road connected the upper reaches of the Nenjiang with Aigun on the Amur River, Amur as well. In November 1931, the bridge over the Nen River near Jiangqiao Mongol Ethnic Town, Jiangqiao became the site of Resistance at Nenjiang Bridge, one of the first battles of the Second Sino-Japanese War.
