A Chinese Coast Guard vessel damaged a Philippine vessel on Tuesday near the disputed Scarborough Shoal in the South China Sea. Both sides quickly accused the other of being responsible for the latest incident in their dispute over the shoal.

In the Chinese Coast Guard’s telling of events, more than 10 Philippine vessels surrounded the shoal, which Beijing refers to as the Huangyan Island. It “implemented regulatory measures against the Philippine vessels, including warnings, route control, and the use of water cannons,” according to Gan Yu, a spokesperson for the service.
