There has been multiple stories in the news recently about crackdowns on Chinese "spies" in the universities. I'm using the word spy loosely there, that's not the word that has been in the news. They talk about it more in the sense of secretly getting funding from China and not claiming it or whatever. My perception is that the belief is that this is a major avenue through which US tech is "stolen".
The administration recently hinted that they will be blocking Chinese apps such as TikTok from being used in the US.
The administration also hinted at breaking the currency peg to the dollar.
