The Philippines on Tuesday accused China’s coast guard of harassment and damaging one of its boats in a disputed area of the South China Sea, and rejected Beijing’s position that it had expelled two vessels from the hotly contested shoal.

The Philippine coast guard said its two vessels stood their ground at the Scarborough Shoal, a key battleground in the South China Sea, but that one sustained damage from use of water cannon by two Chinese coast guard ships.

“This damage serves as evidence of the forceful water pressure used by the China coast guard in their harassment of the Philippine vessels,” Philippine coast guard spokesperson Jay Tarriela said in a statement.
