Dramatic footage shows two Chinese government ships violently colliding Monday while chasing down a Filipino coast guard vessel in a disputed area of the South China Sea.

The U.S. sent two warships to a disputed shoal in the South China Sea, where two Chinese ships recently collided while chasing a boat from the Philippines.

The Philippine Coast Guard (PCG) revealed on Saturday that suspected Chinese signal interference prevented the agency from launching drones during a resupply mission to Bajo de Masinloc earlier this week.

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

It’s hard to call the collision of two multi-thousand-ton military ships “fortunate,” but that’s exactly what analysts are saying about the incident in the South China Sea this week that left a China Coast Guard ship with a heavily damaged bow after it hit a People’s Liberation Army Navy guided-missile destroyer.
