> Why is China an adversary of US?

Every power is an adversary of each other on the world stage. It's not something special that exists between China and the US, each and every power is in a similar relationship. Since there's no higher power to govern it all, the only thing that keeps the adversarial relationships somewhat peaceful is the balance of the power. Otherwise one would assimilate the other. The rest, like the particulars you listed, are just details.

That's just a war-mongering propagandaist talking point.

Absolutely not. It's just people in large, complex groups, with history. Also, it's not about war at all - rather, it's about power. Which can be, and is, achieved in a good many not-war ways.
