A lot of people very often criticise China's non-interference policy as being naive, stupid childish etc.
Now see what is happening today, the hegemon is currently seriously overstretched with new crises popping up like mushrooms every month or so. It needs to allocate resources to deal with them while in the same time they have to contend with China lol
China is basically winning by doing nothing except still existing and giving courage for groups to resist America. Winning by doing practically nothing, Sun Tzu would be proud
