Apparently you are unaware that the Hague Tribunal has already decided that the Phillipines has sovereignty over the Spratly Islands. Moontwat's favourite news organ says so, hence must be true.
Hague Tribunal rules in favor of Philippines, China to ignore decision
China has caused irreparable harm to the ecosystem of the Spratly Islands and breached the Philippines' sovereign rights, the Hague Tribunal has ruled. Beijing has ignored the ruling, saying its islands come with exclusive economic zones, where Chinese people have had activities for 2,000 years.
The court said in the 497-page ruling that “There was no legal basis for China to claim historic rights to resources within the sea areas falling within the ‘nine-dash line',” referring to a demarcation line on a map of the sea from 1947.
China has repeatedly warned that it would not recognize any adverse ruling from The Hague’s arbitration court, which was widely expected. Beijing boycotted the hearings at the Permanent Court of Arbitration, saying that it does not have jurisdiction to decide the dispute.
