You said logical reasons but all you did was repeat standard anti marxist rhetoric a few times. Nations run on internal logic, like all things. Chinas demonstrated interests dont include me. the USA on the other hand, has a history of being unpredictable and invading without any real intent or purpose.

You appeal to history but just compare all the aggressive wars started by the USA vs China since WW2. Tell me who to be more scared of.

China hasn't even done much more than pay lip service to Marx since Deng anyway. They are just the most stable, reliable capitalist superpower right now.
