“On 04 April 2014, the Philippines protested Chinese reclamation on Mabini (Johnson) Reef. The Chinese side rejected the protest. The President raised the Mabini Reef issue in Nay Pyi Taw. The Philippines already included Mabini Reef in the Memorial to clarify Mabini Reef’s physical character,” said in an official statement of Philippine Department of Foreign Affairs.
The said reef is embraced by Philippine Exclusive Economic Zone as defined in United Nations Convention on the Law of the Sea (UNCLOS), a treaty signed by more than a hundred countries including China and Philippines.
In a report from Reuters, “Philippine Foreign ministry spokesman Charles Jose told Reuters that China had been moving earth and materials to Johnson South Reef, known by the Chinese as Chigua, in recent weeks. He said China was reclaiming land in violation of the Declaration on the Conduct of Parties in the South China Sea, an informal code of conduct for the region.”
Jose told Reuters China is about to build an Airstrip in Mabini or Johnson Reef.
China had repeatedly expressed its undisputable historical territorial claims to almost all of South China Sea raising disputes with its neighboring countries in Asia.
