Even if this is the case, do you honestly not think the tradeoff is worth it? Lifting a billion people out of crushing poverty seems worth it even if it came at the cost of giving a dictatorship stronger geopolitical influence.
An authoritarian, nuclear armed government that is bent on expansionism by flaunting the established global rule of law and that is likely to start a world war over Taiwan? No, I don't think that's a worthwhile tradeoff.
I don’t think it’s accurate to say they are bent on expansion, but whether it’s worth it is more up to those 1 billion people to decide their fate and tradeoffs rather than foreign intervention. Oh and, due to China’s history of negative foreign interventions I doubt the population will take kindly to it now.
talking about the US?
China has been nuclear armed since the 1960s. That wasn't a product of the country's industrialization or trade with the West.
