A U.S.-funded project using satellites to track and publish water levels at Chinese dams on the Mekong river was announced on Monday, adding to the superpowers' rivalry in Southeast Asia.
The 4,350-kilometer waterway — known as the Lancang in China and flowing south through Myanmar, Laos, Thailand, Cambodia and Vietnam — has become a focus of competition.
Beijing has dismissed U.S. research saying Chinese dams have retained water to the detriment of downstream nations, where 60 million people depend on the river for fishing and farming.
