Yalu River (Nonni River tributary)
The Yalu River (Chinese: 雅鲁河; pinyin: Yǎlǔ Hé) is a river straddling the Chinese regions of Heilongjiang and Hulunbei'er near the eastern border with Russia. As a right tributary of the Nen River, the Yalu starts on the eastern slopes of the Greater Khingan Range, and flows in the general south-eastern direction through Zhalantun in Hulunbei'er and Qiqiha'er in Heilongjiang. The Yalu flows from the west into the Nen River some 100 kilometres (62 mi) south of Qiqiha'er.
As the Nen then flows to the south and into the Songhua River, and the Songhua, to the east and northeast and into the Amur, the Yalu River is part of the Amur River basin. It should not be confused with another, much larger and better known Yalu River (Chinese: 鸭绿江, Yālù Jiāng), which flows along the China–North Korea border and into the Yellow Sea.
