The country’s military said the structures were spotted during maritime patrols conducted on Tuesday, but it did not give the precise location of the structures or more details as to who erected them or as to their construction, saying only their presence violated international law.
China has been accused of using its vast fishing fleet to help assert Beijing’s territorial claims throughout the 1.3 million square mile South China Sea, though China has dismissed accusations it operates an irregular naval force, or maritime militia, as groundless.
“The Laws of the Sea gives the Philippines indisputable and exclusive rights over the area. These constructions and other activities, economic or otherwise, are prejudicial to peace, good order, and security of our territorial waters,” Philippines Lt. Gen. Cirilito Sobejana said in a statement. “These structures are illegal,” Sobejana added.
Among the features in the Union Banks, which the Philippines calls the Pagkakaisa Banks is Whitsun Reef, called Julian Felipe Reef by Manila.
The reef, which is part of the Spratly Islands archipelago, is claimed by both the Philippines and China. The Philippines maintains that it falls inside the country’s exclusive economic zone. A 2016 ruling by a United Nations tribunal dismissed China’s claim to virtually all of the South China Sea, although Beijing has refused to recognize the decision.
China has unilaterally transformed other reefs in the Spratly chain into man-made islands with substantial infrastructure and military fortifications, including missiles, runways and weapons systems.
Manila has protested the presence of the boats with the Chinese government as a violation of its sovereignty and called for them to leave the area.
“Due to maritime situation, some fishing boats have been taking shelter from the wind near Niu’e Jiao, which is quite normal. We hope relevant sides can view this in a rational light,” Foreign Ministry spokesperson Hua Chunying said last week.
On Wednesday, the Philippine government released images and video of the Chinese vessels, which it says were made on March 27.
Philippine government images going back to March 7 show the Chinese boats in the lagoon.
