On April 26, the Chinese Foreign Ministry accused the Philippines of trying to legalize its occupation of disputed islands in the South China Sea. Foreign Ministry spokeswoman Hua Chunying said China would never agree to international arbitration on the disputed islands, which the Philippines has been seeking.

Earlier this year, the Philippine government called for international arbitration in the South China Sea dispute and notified China of its move. And in late March, the president of the International Tribunal for the Law of the Sea even appointed an arbiter for arbitral proceedings after Beijing "failed to designate its representative within the 60-day deadline".

The South China Sea dispute centers mainly on two aspects: conflicting sovereignty claims over Nansha Islands and maritime delimitation. In both cases, the disputing countries should resolve the issue through peaceful means. By initiating arbitration on the validity of China's claims, the Philippines has actually exposed its lack of legal knowledge and violated the consensus reached on the Declaration on the Conduct of Parties in the South China Sea.
