Let’s be real, you think China allowed Tesla to be the first private owned company for shit and giggles? It’s always been the strategy. Let Tesla hire a bunch of local people and work for a year or two. “Entice” them to leave and work for companies like BYD. It’s a win win strategy for China, you get foreign investment and they fund your local expertise to replace the same product. Especially now that Tesla uses mainly Chinese batteries, it’s pretty trivial to roll the same technology into Chinese product with a bit of political and economical incentives.
