ArchipelagoSpratly Islands
Area1.6 ha (4.0 acres)
Occupied by Vietnam

With an area of 1.6 hectares (4.0 acres), it is the thirteenth largest naturally occurring Spratly island and the sixth largest amongst those occupied by Vietnam.

The island has two parts: the eastern part consists of sand and coral, and the west part is covered with guano. It has a fringing reef. An obelisk, about 2.7 m high, stands on the SW corner. There is little vegetation. It is described by some as heavily fortified.[2] A lighthouse has been operational on the island since May 1995.

The island is also claimed by China, Malaysia, the Philippines and Taiwan.

Recent historyEdit

In 1978 the Royal Malaysian Navy landed on the island and placed markers. However, the markers were subsequently destroyed by Vietnam who now occupies the island.[3]

On 31 March 1979, forces occupying the cay fired warning shots at a boat transporting six amateur radio operators ("hams") attempting a DX-pedition to Amboyna Cay.[citation needed]

In 1982, a Singapore yacht operated by the owner and his wife transporting four German hams on a DX-pedition to Amboyna Cay was fired upon by Vietnamese forces. One of the hams, Diethelm Mueller, was hit by an artillery round and fell overboard. The yacht burned and the rest of the party drifted for 11 days on debris. Another ham, Gero Band, died of thirst the day before the survivors were rescued by a passing Japanese freighter which took them to Hong Kong.[4]
