The ccp can be assured that Chinese shipping will not be subjected to piracy and will continue to be welcomed to ports of call and conduct business.  Chinese shipping will also continue to receive first response services in the event a ship is in distress and needing help, a service that China provides as well.  Part of their service is to not seize and control what it does not own, which is what happened here. 

The big issue is who was involved in the decision making to seize the drone.  Was it a political, military, or naval decision, to violate international law concerning freedom of the seas, laws that protect the livelihood of most of the world's population and allow civilization to thrive?  I am thinking it was a ccp decision made by a hot head.  The Chinese Navy is also suspect.

Unnecessary provocation by China.
