What do you mean that mechanic doesn’t exist in the same way for China? Are you talking like China has achieved a classless utopia situation?
No, the arms manufacturers just don’t have the same level of influence over the government and armed forces that they do in America, and the people in the government who decide whether to drop bombs won’t personally get rich if they buy more bombs.
That isn’t something unique to China btw but basically almost every country except USA and a few others.
Do you think that dynamic wouldn’t exist for any country, including China, that had as much world influence as the US does now?
I mean- yeah, the birdcage model has been supplanted by majority public ownership at this point, the same incentives that create the military industrial complex don’t exist- if you’d like, i would recommend reading “Economy and Class Structure of German Fascism” which can be a handy reference point for the US military complex.
