This is a myth. Most of the Chinese GDP is generated by state owned enterprises. Sure, western capital and trade has allowed it to accelerate the rate of growth, but it would've reached parity with the US and surpassed it even without Western capital. It would've simply taken longer. Plus the Chinese economy is not dependent on exports. https://www.reuters.com/article/china-economy-kemp-idUSL8N2AW6LX They already have the world's largest market for automobiles and this trend will be replicated in other consumer fields.

Ah yes, I've heard about their growing Middle Class. I'll have to do more research on this subject, but it begs the question of how will they keep up with consumption that goes with it? For example, a growing Middle Class will desire more land to live on, but that also means less farm land available and even farm workers to go with it (since we have the same problem in the West, where most kids would rather study for a high paying white collar job than do manual labor picking fruit).

I've found an article that also seems to question this relationship with China's shift to urbanization but their complete dependence on foreign food imports. https://www.scmp.com/economy/china-economy/article/3111623/china-food-security-hows-it-going-and-whys-it-important

Long-term factors affecting China‘s food security include a shrinking rural labour force, the reduction of available farmland by urban development as well as a farmland management system that is an obstacle to modern farming and large-scale cultivation

This is why its been so difficult for the US to decouple from China and move its manufacturing firms away from China. There simply isn't any other comparable country

Prior to Covid, Trump was already in the process of moving manufacturing away from China, but for obvious reasons, it came with a lot of backlash and media negativity. Although it is one thing I did agree with him policy wise.

That said, the future is looking more towards automation anyway, and it would definitely be cheaper to produce robots at home and have them operate locally.
