Chinese Nu Jiang
River, Southeast Asia.
Rising in eastern Tibet, it flows generally south for about 1,500 mi (2,400 km) through Yunnan province, China, and eastern Myanmar (Burma), emptying into the Gulf of Martaban of the Andaman Sea at Moulmein. In its lower course, it forms the frontier between Myanmar and Thailand for about 80 mi (130 km). It is the longest river in Myanmar and is navigable by small craft in certain sections, but dangerous rapids hinder its use as a major waterway.
