You’re not wrong about the US but let’s not pretend China is just “trying to sell stuff”. They’ve got their own genocide going on with the Uyghurs and are famous for espionage
I'm not sure how much the genocide there is real or made up by our propaganda.
I have friends who have travelled in the region and described it as a regular place, with muslims just existing there.
Oh boy you should read about US participation in south america dictatorships and genocides. In colombia we have a century of war fueled by US, check banana massacre to begin with. And each country has its own series.
If we're talking about national interest, it's easy to tell which countries espionage affects us the most.
