I'm Italian/Polish, China has never done anything to me in history.

Whereas I remember multiple times our allies pillaging and colonizing the country.

Not a fan of their espionage, lack of IP respect and human rights record (albeit we should also look at ourselves on the last one as well). But those are things that could've been challenged diplomatically through economical levers imho.

The only reason China suddenly became the enemy is because their GDP growth put them as the world's biggest economy in few decades and Washington wasn't happy with this.
