Yalu River (Nonni River tributary)
The Yalu River (Chinese: 雅鲁河; pinyin: Yǎlǔ Hé) is a river in the northern Manchuria, a right (western) tributary of the Nonni River. The Yalu starts on the eastern slopes of the Greater Khingan Range, and flows in the general south-eastern direction through Inner Mongolia (Zalantun Banner) and Heilongjiang Province (Qiqiha'er). The Yalu flows into the Nonni River some 100 kilometres (62 mi) south of Qiqiha'er.
As the Nonni then flows to the south and into the Sungari, and the Sungari, 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 (鸭绿江, Yalu Jiang), which flows along the Sino-Korean border and into the Yellow Sea.
