Topic - Mekong River

The Mekong is a trans-boundary river in Southeast Asia. It is the world's twelfth longest river and the seventh longest in Asia.From the Tibetan Plateau the river runs through China, Myanmar, Laos, Thailand, Cambodia, and Vietnam. The extreme seasonal variations in flow and the presence of rapids and waterfalls in the Mekong make navigation difficult. Even so, the river is a major trade route between western China and Southeast Asia. - Source: Wikipedia
