Video footage shows the South China Sea chase and the aftermath, including "substantial damage" to the Chinese Coast Guard ship, Manila said.

A Chinese cutter and guided-missile destroyer collided with each other in the South China Sea on Monday during a botched blockade attempt of Philippine Coast Guard vessels ten nautical miles off Scarborough Shoal in one of the most severe incidents among Chinese forces to date.

The Philippine military has blamed China for a collision between two Chinese navy and coast guard ships in disputed waters.
