The difference is, Europeans used to trust their US partners, and built a lot of infrastructure on US services. This trust has been betrayed, so things now need to change.
It never existed to begin with with China, so no change is necessary.
That's not "melodramatic".
There never was a relationship of mutual trust, it was always a relationship of Europe being under the wing of the US as a buffer against the USSR.
The US now wants to push Europe out of the nest, but most Europeans have only ever known life "living in their parents house".
Building an independent Europe is not compatible with the current European ethos of work/life/life/life balance, and will likely result in Europe either coming back to the US, falling into economic chaos, or moving into daddy Xi's house. They are a socialist country after all...
