The Philippines has initiated arbitration proceedings on the South China Sea through the United Nations Permanent Court of Arbitration. Its No.1 and No.2 arbitration requests are to let the court rule that China's historical rights in the "nine-dash line" area of the South China Sea are against the UN Convention on the Law of the Sea, which was concluded in 1982, so as to deny the legality of China's interests.

To realize this purpose, the Philippines has intentionally distorted the facts, made guesses about China's historical interests and interpreted UNCLOS to suit itself.

Manila pretends to be blind to the basic historical facts, claiming that historically Chinese people had no activities in the South China Sea, and China lacks historical connections with the sea.
