Chinese businesses don’t get the loans they need to grow if they are not 100% inline with the party. BYD may not be a genocidal slave owner but they will support China’s decisions every step of the way.

They really did a min-maxed speedrun of capitalism. The rich get to be rich, the government gets to imprison, enslave, and execute anyone who doesn’t support them, and that let them undercut all the existing big names in manufacturing. I would bet that there is a Chinese manufactured part in every home in the world that also has electricity and plumbing.
