that it considers to be within its continental shelf. Swallow Reef (Layang Layang / Terumbu Layang / Pulau Layang Layang) was under control in 1983 and has been turned into an island through a land reclamation which now also hosts a dive resort. The Malaysian military also occupies Ardasier Reef (Terumbu Ubi), and Mariveles Reef (Terumbu Mantanani). Basis of Malaysia's claim Malaysia's claims are based upon the continental shelf principle, and have clearly defined coordinates within the limits of its EEZ defined in 1979. This argument requires that the islands were res nullius and this requirement is said to be satisfied as when Japan renounced their sovereignty over the islands according to the San Francisco Treaty, there was a relinquishment of the right to the islands without any special beneficiary. Therefore, the islands became res nullius and available for annexation. The Philippines The Republic of the Philippines claims the Spratly islands and are based on sovereignty over the Spratly Islands on the issues of res nullius and geography. Basis for the Philippine claim The Philippines contend their claim was res nullius as there was no effective sovereignty over the islands until the 1930s when France and then Japan acquired the islands.

Therefore, the islands became res nullius and available for annexation, according to the claim.

In December 1974, Cloma was arrested and forced to sign a document to convey to the Philippines whatever rights he might have had in the territory for one peso. Cloma sold his claim to the Philippine government, which annexed (de jure) the islands in 1978, calling them Kalayaan. On 11 June 1978, President Ferdinand Marcos of the Philippines issued Presidential decree No. 1596, declaring the Spratly Islands (referred to therein as the Kalayaan Island Group) as Philippine territory. The Philippine claim to Kalayaan on a geographical basis can be summarised using the assertion that Kalayaan is distinct from other island groups in the South China Sea, because of the size of the biggest island in the Kalayaan group. A second argument used by the Philippines regarding their geographical claim over the Spratlys is that
