Location, topography and structures

Johnson South Reef lies adjacent to the Vietnamese-controlled Collins Reef (also known as Johnson North Reef) which lies 6.4 kilometres (4.0 mi) to the northwest. It is naturally above water only at low tide. It houses a number of small buildings, wharves and a fortified Chinese maritime observation station.

On 12 July 2016, the tribunal of the Permanent Court of Arbitration concluded that Johnson Reef contains, within the meaning of Article 121(1) of the Convention, naturally formed areas of land, surrounded by water, which are above water at high tide. However, for purposes of Article 121(3) of the Convention, the high-tide features at Johnson Reef is rocks that cannot sustain human habitation or economic life of their own and accordingly shall be entitled to 12nm of territorial sea measured from its baseline but have no exclusive economic zone or continental shelf.
Territorial disputes

Johnson South Reef is currently occupied by the People's Republic of China and claimed by Vietnam. It was the site of the 1988 Johnson South Reef Skirmish between the PRC and Vietnam that resulted in the death of 64 Vietnamese soldiers, two Vietnamese boats being sunk and the Chinese occupying the reef.

In order to prevent the reef from submersion caused by erosion, and to maintain the claim to the EEZ, the PRC government built an embankment building, and Johnson South Reef surrounded the building in the early 1990s.

In July 2012, to further reinforce their claim, a Chinese fleet of 29 fishing vessels from Hainan protected by Yuzheng 310 (a fishery administration patrol ship) spent 20 days fishing in the region.
Military development
During 2014, Chinese reclamation work expanded the usable surface area to 11 hectares, accommodating what appears to be a military and radar base and a small harbour. As of May 2016, the Chinese reclaimed 109,000 square meters (10.9 ha) of land.
In late 2016, photographs emerged which suggested that the reef has been armed with anti-aircraft guns and a CIWS missile-defence system.
