That’d be giving in to Chinese provocation. They’ve been doing this harassment in hopes of the Philippine government giving up and complying with the Chinese demands, or the Philippines getting riled up and firing the first shot. The latter will give China the “moral ground” or at least ammo for their propaganda.

IMO, what the Philippine military has been doing is a good countermeasure to this harassment: asserting their rights (as per the arbitral ruling, which China refuses to honor), publicizing Chinese aggression all the while building up its defenses and network of allies.

Punching a bully in the face might feel good, but this bully is also crafty and sneaky, that some care is needed dealing with it.
