MANILA: The Philippines said on Monday it executed a "special operation" to remove a floating barrier installed by China at a prime fishing patch in the South China Sea, a move that could stoke tension after a years-long detente in Asia's most disputed waters. The Philippines expressed outrage on Sunday and shared images of Chinese coastguard policing a long, ball-buoy barrier near the Scarborough Shoal, a rocky outcrop 200km from the Philippines and the site of years of intermittent flare-ups over sovereignty and fishing rights."The barrier posed a hazard to navigation, a clear violation of international law.
