not incident. Taiwanese coast guard rammed them when they were leaving.
The commonality with the Philippines is that they were acting at either the direct or indirect orders of some certain extraregional country. Humiliating them and crushing their spirit is the only way for them to see reason and the way to do that is to hit them hard without being exposed to any substantial retaliation.
Ramming is an obvious act of aggression, ramming and killing even moreso. The Philippines are not ramming anyone, they are being rammed, which is why they are upset. The difference is that Taiwanese see themselves at fault, Filipinos don't.
Now if Filipinos are dumb enough to kill Chinese fishermen, that is a different story of course. But so far they have not done anything aggressive. Which should make it quite clear that the ones making the decisions are not insane nationalists looking to commit suicide. They are trying to do the opposite, to paint themselves as victims. That's why I am in favor of the current restrained actions, because slow and gradual pressure denies them most of the opportunity. CCG being more aggressive is what the Filipinos want.
