China subsidized the selling and buying of EVs long ago (00's) when they saw an opportunity and took the risk. They knew they couldn't compete on the combustion market. It is paying off, not only for that industry but also the battery market, and innovations around both sectors.
The US and Europe snored. Elon didn't, he had a vision, unfortunately his hubris and arrogance kinda got the best of him.
Can you blame China? You have capitalist markets taking advantage of their labor pool; they aren't stupid... they took advantage right back. Brilliant, actually.
And now we're seeing it with their space program, their military (kinda) and their technology.
