The Philippines and China are trading accusations over the latest collision between their vessels in disputed waters in the South China Sea.

The Philippine government said on Sunday that two resupply ships and a patrol boat were obstructed by Chinese Coast Guard and maritime militia vessels off the Spratly Islands in the morning.

A video released by the Philippine government shows the patrol boat surrounded by Chinese vessels and being water-cannoned, and a Chinese Coast Guard ship ramming into the side of one resupply vessel.

The government says one of the resupply vessels suffered damage to its engine, and the patrol boat towed it back to a port.

Philippine officials accused the Chinese vessels of "unprovoked acts of coercion and dangerous maneuvers" that "put the lives of Filipino crew members at risk."

The Chinese Coast Guard said the Philippine vessels illegally entered the waters, and one of them "made an unprofessional and dangerous sudden turn, intentionally ramming into a Chinese Coast Guard vessel."

The Chinese side argues that the Philippine side bore full responsibility.

This is the second day in a row that the two countries have been involved in a maritime incident.

On Saturday, the Philippines said Chinese Coast Guard ships fired water cannons at its resupply vessels in another location in the South China Sea.
