No. Even if they dramatically changed on all fronts, became a democracy, promoted LGBT+ and racial civil rights, broke up their concentration camps, stopped surveiling citizens, gave people true elections, and stopped cracking down on political opponents, their nation is facing an extremely serious gender and population imbalance, one that will have drastic impacts on their society and stability in the next 30 years. A large portion of their workforce is going to retire and cannot be sustained by the smaller population that are kids and teens now. There's also a severe gender imbalance from the One Child Policy favoring boys over girls. There's no getting off that train, and shit like incel culture and a ton of retirees causes bad political instability. Or wars, to distract from problems at home, like what Russia is doing.
It's going to be a massive problem since they don't have much in the way of immigration, and even if they got a ton of people pregnant now, they are still facing down a 10+ year deficit of people.
Hell, the only reason why we aren't in the same boat is that we didn't implement boneheaded policies like that, and immigration helps offset our birthrate being below the replacement rate of people. We depend on immigrants as much as they depend on us.
