It's pretty clear the US is also joining in. This includes under Obama, who attempted to economically isolate China with the TPP, but has doubled down under Trump. The strong tariffs on Chinese goods (presented under flimsy pretences of protecting American workers) are a clear indication that the interests that back Trump wish to sever economic ties with China, making conflict between the two nations less economically damaging.
I don't really see this - a lot of Republican industry groups are against the trade war and I don't think this is something a more 'normal' Republican would've did. It's been clear that Trump hasn't been able to digress significantly from previous American foreign policy but considering there's a lot more presidential autonomy over trade than anything else, I think this is just Trump's weirdness as a president coming through. (If we want to go for something really antagonistic, it's notable that the plan to try banning Chinese foreign students from American universities under the pretense of stopping espionage was shot down.)
Besides that, I agree with coloniac that there isn't much desire for a full-scale Cold War among Americans nor do there seem to be many public figures who really care much about China as an issue. Outside of Trump (whose ire for China doesn't seem particularly exceptional compared to other countries) and Rubio, most politicians and people seem to care more about the 'sexier' issues of the Middle East and Russia. That Cold War bipartisan consensus that anticommunism should be the no. 1 foreign policy priority just isn't there imo.
