By making the government the controlling monopoly, China ends up with a form of capitalism where externalities apply to other countries rather than surrounding corporations and citizens. That's kinda interesting compared to how most other capitalist nations are handling their shit right now. You can do 'common good' stuff like force meme EVs on a significant national scale, where other developed nations are absolutely floundering.
What's even more interesting is how rapid that has occurred as compared to how recently China was an absolute polluting demon. Still are, but the rate of change/velocity towards addressing it is worth paying attention to.
