He's been telling me this, for years. It's not a secret. The information has been out there, for ages. I'm surprised that the administration didn't understand this.
By acting against China that means I applaud moving manufacturing to Vietnam. I want to help Botswana grow - and I wish there were more countries in Africa I could name that seem to be on a good path (I cannot name the majority of countries in Africa, the ones I can are because they are in the news for bad things happening. I'm not even sure Botswana - I mostly know about them because last time I brought up Africa someone from there said their country was an exception).
Overall the world is better off with a lot of trade. Comparative advantage is real. There are things I can do that I don't want to become good at. However we also need to be aware that not everyone in the world is the friend of freedom and some must be cut off lest they grow. Nobody is perfect though, so you can't cut off everyone.

Making what are essentially strategic decisions in this "shoot from the hip" fashion is what lands us repeatedly in these situations. By way of illustration, let me try one from the 1980's out on you:
"By acting against Iran that means I applaud men like Saddam Hussein and Osama Bin Laden"
(In fairness to the americans who made that colossal blunder, I'll assume that, to them, it seemed a good idea at the time. They were simply not long term thinkers. So no one ever asked, "Hmm, what comes next though?")
We, as a people, need to start thinking a bit further ahead than the ends of our noses.
