China and the Philippines have traded blame over two collisions in the South China Sea involving their vessels, the latest in a series of maritime confrontations in the disputed waterway.

Iran PressAsia: The incidents happened near Second Thomas Shoal in the Spratly Islands, a hotly contested region where Beijing deploys ships to assert its claims over almost the entire sea.

A Philippine government task force said the "dangerous blocking manoeuvers of China Coast Guard vessel 5203 caused it to collide with the Armed Forces of the Philippines-contracted indigenous resupply boat" about 25 kilometres (15 miles) from Second Thomas Shoal.

China said the "slight collision" happened after the resupply boat ignored "multiple warnings and deliberately passed through law enforcement in an unprofessional and dangerous manner", state broadcaster CCTV reported, citing the foreign ministry. 219
