The relevant Declaration on the Conduct of Parties in the South China Sea (DOC) was signed by China and the 10-member Association of South East Asian Nations (ASEAN) in 2002. The agreement binds the ASEAN countries to refrain from occupying uninhabited reefs and shoals apart from building new structures in the sea.
China’s Foreign Ministry urged the Philippines to stop its “malicious hyping and provocation” over the South China Sea dispute, immediately cease its relevant "illegal" construction activities, and withdraw all personnel and facilities from the islands and reefs.
China's complaints against the Philippines follow Manila's repeated accusations that the agreement had already been violated by China's construction work.
In early March, Chinese Foreign Minister Wang Yi said construction on the reefs that China controls near the disputed islands is lawful and poses no threat to other countries.
