This most recent PRC interference with a U.S. Navy ship in the Yellow sea these past few days appears consistent with an ongoing, stepped-up PRC policy looking towards an expansion of its territorial claims well into international waters. To be sure, China’s territorial waters claims are not new, it is just that we are now seeing more aggressive and confrontational action on the part of the PRC. This most recent China/U.S. naval confrontation in the Yellow Sea follows last month’s nearly mirror-image confrontations of the U.S. Impeccable in the South China sea. These events bear careful watching as they pose the risk of misunderstanding, miscalculation and injury not only to the U.S. and China, but to competing territorial claimants in the Region as well as international maritime players.

Complicating this picture, we need to be mindful that Hanoi, having finally resolved a 30-year northern border dispute with China, is beginning now to focus on its age-old dispute with China over the South China sea’s Paracel and Spratley Islands. While, to be sure there are other national interests claimed over these islands, the Vietnamese are the most likely to pose intense resistance to China’s claims in the South China Sea.
