Eh, US is threatening to annex Greenland, part of Panama and Canada, which may be more relevant for EU actually.
I can produce quite a list of human rights violations from the US too, if we are playing this game.
I was not trying to paint China as a happy friendly country. I was just saying that right now China is less of a threat to EU than the US, when those in power in the US numerous times voiced their ideological hatred for Europe
