I feel sorry for the Chinese sailors on the forecastle who were apparently injured or killed. That said, the Chinese have been playing a dangerous game and lost. Their riskiness was bound to backfire on them.
For the past several years, Chinese Navy and Coast Guard ships have been harassing Philippine ships in the disputed waters of Scarborough Shoal, a hotly contested grouping of islets and reefs that lie in the northeastern end of the South China Sea. On Monday, these aggressive actions caught up with Beijing when one of its Navy guided missile destroyers collided with one of its Coast Guard cutters, likely rendering the cutter at least temporarily unseaworthy.
The badly damaged vessel had been chasing the Philippine Coast Guard (PCG) cutter BRP Suluan on a resupply mission in the shoal at the time. The collision came during a period of particularly heightened geopolitical friction between China and the Philippines, primarily over Beijing’s widely rejected claims to virtually all of the South China Sea.
