American foreign policy since the cuban revolution has openly and intentionally been aimed at depriving Cubans of food in the hopes that the people would revolt. It’s being denied the ability to trade with other sovereign nations at the barrel of a gun.
Chinese foreign policy has rarely deviated from moderate, trade-oriented and relatively apolitical over the past few decades. I think the massive allocation of US taxpayer funds toward negative coverage of China has swayed your opinion to the most hawkish extreme. None of these accusations really exist outside of the anglosphere and HK/Taiwan based Sinophone disinfo networks, however most of them are widely acknowledged as crimes that the US has committed in the very recent past in some capacity.
