The more valuable diversity is the diversity of thought, not the diversity of culture. Elon knows that difference, too, having come from South Africa. I've often thought that as long as ITAR-concept barriers are put in place to avoid giving monarchs more power regarding the intel China factory will use, that it will be fine to let them have electric vehicle intellectual property, manufacturing, and products, since they can use cars too. That's pretty easy, considering that the tech necessary to make electric cars viable are not usually weapons-level intelligence. Although not a zero area of effort, it doesn't seem like a high cost to freedom to let China be privy to the success of Tesla vehicles, solar, and home storage. Also, since their factory is using local funds and local workers to build local resources into local resources for local users, I see it as neutral regarding import-export imbalances, which in today's major problems regarding that is considered quite a win.
This does open the door to the possibility in the future Tesla GF3 will try to export into areas that will hurt the local economies of those areas. I'm generically against that, but it would fall to the people of those areas to make certain the correct restrictions are in place to prevent that from being a problem. Right now, USA is suffering greatly from doing that wrong, but is directionally fixing that at the moment, and we need more fixing of that. As far as Tesla is concerned, they are correctly making cars for the USA market from the USA market, but also importing a bit too much from outside, but eventually I think that can even out. I also look forward to a time other continents can make for themselves with respect to Tesla models. The various European car markets are already going ahead with local production of EVs from competing manufacturers in Europe, so that's good. (It doesn't directly help Tesla, though.)
The world can use all the batteries it can get. Already Tesla has shifted the balance of batteries being made to USA greatly. More! I wonder what company will build a battery plant in USA next. I know if I were MbS, I'd be building a handful in KSA right now (underground and far from missile/drone reach). I'm surprised Norway doesn't have a bunch of battery plants already. Easy pickings for them. It's a cut-throat business with huge downside and longer term huge upside. They're some of the only places that can easily afford the downsides to make it to the long term. (Few battery manufacturing processes survive, and those that do are only enablers, not themselves profit centers. The enabling technologies allow for survival, not always riches direct from the solar, home batteries, and cars they make possible. But survival is a big win in the game of energy now that we are transitioning from mined fuels. We make it out the other side with clean energy we own and no one can take away without violence. Upon that, we are bathed in riches of plentiful life. It itself is just a means to an end, with some opportunities along the way but not necessarily a windfall.)
