Kong River

The Kong River (Vietnamese: sông Sê Kông) is a river in Southeast Asia that is also known as the Xe Kong or the Se Kong. The river begins in Central Vietnam's Thừa Thiên–Huế Province and flows 479 kilometers (298 miles) through southern Laos and eastern Cambodia. It flows into the Mekong River near the Cambodian town of Stung Treng. A portion of its path forms the international border between Laos and Cambodia.

The Sekong River has tributaries that originate in the Truong Son mountain range near the border of North-Central Vietnam and South Laos, flow west and southwest through the provinces of Sekong, Attapeu in Southern Laos, Stung Treng in Northeastern Cambodia, and then empty into the Kong River near Stung Treng town.

The entire Sekong basin is 29,750 km2 wide, with 750 km2 on Vietnamese territory (around the A Sap and Se Kaman rivers originating in Kontum), 23,000 km2 in Laos, and 5,400 km2 in Cambodia.
