Spratly and Sabah Islands are two territories claimed by Philippines. Spratly is a group of 52 Islands of which only seven are occupied by Philippines. Sabah islands are a disputed territory between Malaysia and Philippines and are presently occupied by Malaysia.
According to my extensive research, NO ONE own the Spratly Islands, but the Chinese dynasty during year 200 AD claim it and saying those part of the Island are belongs to them. In addition, Chinese dynasty named this island "Nansha Island." This island was not Spratly back since 1791 Captain Spratle name under his name. For sure, China never own Spratley Island, but more relatively (but not really, its close) own Philippine government..
