The island has been occupied by Vietnam since 1974, (first by South Vietnam, then by the Socialist Republic of Vietnam after 1975). However, no Vietnamese stations have been built. By the later half of the 20th century, no nation had complete sovereignty on the islands.
Geography
Part of the Tizard Bank,[1] Sand Cay lies 6.2 nautical miles (11.5 km; 7.1 mi) east of Itu Aba Island, which is occupied by Taiwan. It is 450 metres (1,480 ft) long, 102 metres (335 ft) wide, and has an elevation of 3.5 metres (11 ft) to 3.8 metres (12 ft) at low tide.[2] There is a 41 metres (135 ft) high light house on the islet.[3] Sand Cay is commonly confused with Sandy Cay which is a sandy shoal (coral reef) near Thitu Island.
In 2022, news reports indicated that the Vietnamese government was engaged in dredging and landfill operations to expand the size of Sand Cay, Namyit Island, and Pearson Reef. The total area of the land reclaimed in these operations was estimated to be 170 hectares (420 acres). [4]
