China needs us economically as much as we need them for manufacturing. Sure, we’re trying to be more independent and make more domestically, and they are trying to be more independent economically through BRICS. Neither country is doing a very good job of attaining their goals of independence, but to keep up appearances both countries like to simultaneously pretend there’s not a relationship and also that they are the top in the relationship.
The reality is both countries have some wealthy “oligarchs” who exploit workers and governments that mostly only work to benefit themselves and their oligarch friends. China will take out an oligarch here and there when they decide they’re getting too powerful, and Americans get to elect some of our leaders, other than that we’re not very different. Deep down both governments understand it would be political suicide to antagonize the other to the point meaningfully harming them. At least both current governments that is, Trump is probably too dumb to realize we need each other, so that’s a potential wild card, but North Korea is almost certainly a bigger threat to both the US and China than we will to each other for decades.
They actually recently (within the last few months) agreed to join a larger grid. So that should be a bit less of a problem this year. It is Texas though, so there’s always the chance they turn around and shoot themselves in the foot.
