China is exporting the most important kind of revolution, one welcomed by the vast majority of any society regardless of ideology- it's exporting the revolution of human development, in infrastructure projects, in non-exploitative loans, in the industrial development of countries that have had the means of it withheld and suppressed by western capital, in education, in hospitals and healthcare and vaccines, in roads, ports, rail, telecom infrastructure, etc...
For revolutions which aim to change the socioeconomic structure of a society- it's best left for the locals to figure out; IMO if China tried to export that sort of revolution, especially in the current circumstances, it would only lead to disaster- to a fragmenting of the global southern, non-western world. Foreign exploitation can be countered by providing a far superior, non-exploitative alternative; indigenous problems require indigenous solutions.
IMO fighting is generally better than being seen as a pushover (which will then invite anyone else to come take whatever they want from you). But fighting is almost always not a good strategy.
If things are going to come to blows in some "Mad Max" scenario, in most situations wouldn't it still be better to fight unfairly (hit first, hit dirty, join in a group, hit while they're not even looking)? Violence is always an answer, but opening yourself up to violence is almost always a bad idea. Better to be a dirty, cheating coward than dead.
