Increased encirclement & isolation (economic & political persona non grata) by a large group of the liberal affluent nations is the only approach that will work to curtail military attacks like this one. The CPC ego is extraordinarily fragile, the party's self-esteem gets injured very easily, and that should be taken advantage of. Essentially all the highest GDP per capita nations are liberal allies, they should band together and begin excluding China in unison if these military attacks continue.

It's the sort of organizing the US used to be good at, and is presently failing at miserably (for obvious reasons). Germany, France and Britain are also falling down on the job as well (because they're economically scared), so there's plenty of blame to go around.
