I agree that China is a big threat, but trade wars is a bad way to address it. History has shown that the US pretty much always ends up losing in a trade war. Mind you, I don't know what the right solution is, but I do know that trade war is not it.
It would of course be ideal if EU and all democratic countries got together, but they (just like Biden) unfortunately have no interest in doing so. Biden believe that it’s USA’s self-interest to see China prosper.
