The longest river in China is the Yangtze River, which is also known as Chang Jiang. It is also the longest river in Asia. It measures about 6,380 kilometers in length.
The Yangtze River is the third-longest in the world, and only the Nile in Africa and the Amazon in South America are larger. The river is known as the unofficial dividing line between North and South China. Officially, for geographical division, the Qinling-Huai River is the defined line. The Yangtze River is important to China in terms of its historical, cultural and economic impact as the river allows for the easy transportation of goods to and from the people of China.
