Created from Britannica articles using AI. AI can make mistakes, so verify using Britannica articles.

The three major rivers that flow through the deep, V-shaped valleys of western Yunnan are:

  • The Salween (Nu) River, which flows between the Gaoligong and Nu mountains.1
  • The Mekong (Lancang) River, which flows between the Nu and Yunling ranges.1
  • The Black (Lixian) River, which flows between the Wuliang and Ailao mountains.1

These rivers are characterized by currents that are too swift for navigation, though they possess significant potential for hydroelectric power.1
