Cornwallis South Reef (Vietnamese:Đá Núi Le;Chinese:南华礁;pinyin:Nanhua Dǎo), also known asOsmeña Reef (Filipino:Bahura ng Osmeña), is acoralatollreef in theSpratly Islands in theSouth China Sea. It covers an area of about 10 km by 5 km, and is entirely submerged at high tide.[1]
The atoll is controlled byVietnam, but is claimed by the Philippines andChina as part of its claim to the entire Spratly Islands. In 2009, Vietnam, in a submission to theUN Commission on the Limits of the Continental Shelf (CLCS), accepted that its continental shelf did not include Cornwallis and therefore they have no entitlement to exploit it.[1]
The atoll has been subjected to a small amount of development by Vietnam. Structures have been built at three points on the atoll, in 2014/15 two access channels were dredged to allow ships enter thelagoon, and in 2015 small-scaleland reclamation was started beside the new access channels.[1] Much of the reclamation work was washed away byTyphoon Melor in December 2015.[2]At the end of October 2022, Vietnam returned to building up the reef near the southwest entrance channel of the reef, close to Nui Le A Island. By 2025, the islands will have a total of 7.5 hectares distributed between Núi Le C: 5 hectares and Núi Le B: 2.5 hectares.[3]
