Towing them won't achieve anything long term, they'll just send back more disposable people. China doesn't have that many low paid no lifers they can buy to sit on an anchored ship in medieval sanitary conditions for months to years.All this ramming but that ship is still in the shoal. I don't think ramming is going to work anymore. China will have to escalate. Directly towing the ship away is probably the next course of action
The real problem is that Philippines hasn't felt the pain yet. We need a shooting war, a severe whipping of the whole Philippines national character, the likes of what the IJA and US army did to their population in their past. Only then will they love China, like they love Japan and US.
China should wait 3-10 years though. The situation in middle east and Europe will serve to stretch US thinner or even so thin they cannot do anything for Philippines at all. Also the militarization of China in both national character and military investment has not yet begun.
