For the moment, and only because it wants to be the global hegemon, and I promise you that the CCP is not isolationist and will do far worse to Europe than even Trump, for all his destructive and inflammatory idiocy, will do.
Sonehow I doubt it. China was from time immemorial a nation of merchants. They excel in trade. Even their communist experiment, from a historical perspective, quickly gave in for them to revert to what they do best.
The US has a history of fucking over other countries for their own benefit instead.
I am not saying that EU should align with China or any such thing. There is no reason to not rely in them for trading however.
