What the Evidence Shows
Multiple credible news sources from August 2025 report that during a maritime incident near the contested Scarborough Shoal in the South China Sea (referred to by the Philippines as the West Philippine Sea), a Chinese navy warship and a Chinese coast guard cutter collided with each other. This collision occurred while both Chinese vessels were attempting to block and chase away a Philippine Coast Guard patrol ship, the BRP Suluan, which was escorting aid vessels in the area.
The collision was between two Chinese vessels, a navy warship and a coast guard ship, not directly between Chinese and Philippine ships.
The Philippine Coast Guard vessel was involved in the incident but was not reported to have collided with any Chinese ship.
Video footage released by the Philippine Coast Guard clearly shows the Chinese ships crashing into each other during the pursuit.
The incident has been widely covered by international media, highlighting tensions in this disputed maritime region.
Therefore, the statement that "The Chinese navy ship against the Philippine coast guard crashed at the water in the sea of West Philippine Sea and the navy coast guard crashed against the Chinese navy ship" is accurate in essence, though it is more precise to say that the collision was between two Chinese vessels during their attempt to intercept a Philippine Coast Guard ship rather than a direct collision between Chinese and Philippine ships.
