It's concerning that someone from the EU is still asking this question. How is there any doubt left in you? Yes, of course both are adversarial countries, and shouldn't be treated all too differently. In the short-term, the US is the bigger threat, as they've shown they're much more willing to use the power they have to cut off access than China.

As someone from the US I would suggest viewing both as adversarial. I don't really trust my own government, but if I was born abroad I would trust them even less.

You absolutely can. We see a huge uproar in European enterprises against US software/vendors/etc. Many companies are halting their cloud migration because they are now worried that the current US government could decide to just pull the plug or something otherwise inane.

And to be fair only US is openly hostile to EU.

As someone from the EU, please do!

I don't know why you're being downvoted, the US has been way more belligerent towards the EU recently than China.
