The Philippine military on Tuesday blamed China for the collision of two Chinese navy and coast guard ships while trying to drive the Philippine coast guard and fishermen from a disputed shoal in the South China Sea.

The United States deployed two warships on Wednesday in a disputed South China Sea shoal, where two Chinese navy and coast guard ships collided two days ago while trying to drive away a smaller Philippine ship in a high-seas accident captured on video, alarming several Western and Asian countries.

A US Navy guided-missile destroyer performed a so-called Freedom of Navigation operation (FONOP) near disputed Scarborough Shoal in the South China Sea on Wednesday, just two days after two Chinese military vessels collided while chasing a Philippine Coast Guard ship in nearby waters.
