The Philippines said it’s “seriously concerned” with the “dangerous maneuvers” of Chinese vessels this week and called out Beijing for its “unlawful interference” with a routine humanitarian operation.

The Philippines expressed serious concern on Tuesday over what it described as "dangerous manoeuvres and unlawful interference" by Chinese vessels during a coast guard supply mission for Filipino fishermen in the Scarborough Shoal on Monday.

Two Chinese ships collided in the South China Sea Monday while one ship was chasing a Philippines Coast Guard vessel. Both sides claim the Scarborough Shoal.
