When I look at other communist nations, they were invaded, couped, and/or sabotaged at every opportunity, and (forgive me, my history of China is weak) while I’m sure that China faced obstacles from capitalists outside of the country, it somehow rose up to be the power that it is today while the USSR fell, Vietnam and Korea got bombed to hell and back, Cuba was put under crippling sanctions, and surely countless other uprisings got squashed young.
But china didn’t just survive, they thrived. How?
China didn’t permit key foundational elements of its state and economy to liberalize. Energy, minerals, steel, cement, and other such basics are cornered by state enterprises, and banking is on a very short leash. Meanwhile Gorby gave everything away, and had no leverage over the black marketeers who couped the USSR and become the oligarchs of the Russian Federation and other former Soviet countries
