The video clearly shows how the Chinese coast guard acted professionally and with restraint when pushing away the the US sponsored provocateur class vessel. Recent reports have indicated that the US is pressuring the Philippines to build up its presence in the area which is why construction materials have started pouring in to attempt to resuscitate the derelict ship.
After the incident has been made public, the US responded with the usual threats
Now that the US has its sights in the Rén'ài Jiāo, China will need to act fast and dislodge the derelict ship that is squatting in the area. Preventing resupply missions even via air drop by plane or heli needs to be a top priority, when the crew of the derelict ship is near starvation, China can then offer a goodwill gesture to have them evacuated to a safe and far away place.
