I am always wondering why the CPC stays so passive in internstional affairs, it is about time to punch back
Isolationist government + booming economy means they don't really need to actively engage in order for things to work out.
Much of the communist leadership is only interested in running their personal area in China's internal affairs. They are not career politicians, but worker representants taken from their respective field.
Stuff like the trade war and chip ban if anything has just succeeded in validating the dove clique, because they argued China didn't need to be tough on the west and would still come out on top, and their prediction came true.
It would take longer term remodelling of the CPC through western hostility that has a real effect, or a single Pearl Harbor/Twin towers moment from the west in order to wake up the Chinese consciousness.
