Chinese ships prevented two Filipino civilian vessels hired by the Philippine navy from reaching Second Thomas Shoal on Sunday, the Philippine Department of Foreign Affairs said in a statement. The shoal is called Ayungin Shoal by Manila and Ren'ai Reef by the Chinese.
"Ayungin Shoal is part of the continental shelf of the Philippines and therefore, the Philippines is entitled to exercise sovereignty rights and jurisdiction in the area without the permission of other states," the statement said. China's actions "constitute a clear and urgent threat to the rights and interests of the Philippines" under the Law of the Sea, it added.
"For 15 years we have conducted regular resupply missions and personnel rotation without interference from China," he said.
He said the Chinese ships used digital signs, sirens and megaphones in ordering the Filipino vessels to leave. The Filipinos returned to Palawan, the nearest Philippine province east of the Shoal.
China's charge d'affaires was summoned and handed the protest note. Hernandez said that as in the past, Beijing rejected the protest.
Less than a month ago, Manila also protested a Chinese water cannon attack on Filipino fisherman near another disputed shoal. No one was injured in the January 27 incident at the Scarborough Shoal off the country's main island of Luzon in the north.
