Concern is mounting among some scientists that China's reclamation work in the disputed Spratly archipelago of the South China Sea has done severe harm to one of the most important coral reef systems in Southeast Asia.
China's use of dredged sand and coral to build artificial islands on seven reefs had also damaged reef systems beyond the outposts, meaning the affected area could be greater than first thought, several scientists who have studied satellite images of the Spratlys told reporters.
Those concerns contrast with repeated official Chinese statements that Beijing is committed to protecting reefs and the broader marine environment in the South China Sea in keeping with its obligations under United Nations conventions.
