Lesser Khingan (; Russian: Малый Хинган, Maly Khingan) is a mountain range in China's Heilongjiang province and the adjacent parts of Russia's Amur Oblast and Jewish Autonomous Oblast.[3]
In Russia, the range is part of the Khingan Nature Reserve.
In China, the Khingan mountains are divided into the Greater Khingan and Lesser Khingan. The Lesser Khingan range runs roughly from the northwest to the southeast and separates the valley of the Amur (Heilongjiang) River from that of the Nenjiang River. The mountain range then turns toward the east and north-east, entering Russia.[4] The Amur/Heilongjiang, which is a border river, forms a gorge when crossing the mountain range.
