Fascism is more complicated than that, and while China is nationalistic it's not running on the kind of ultranationalism that, say, Nazi Germany had. Modern China doesn't meet any credible definition of fascism.

You're describing the US to a tee. China is a unlike what you think. But unfortunately your brain has been molded by the western propaganda that China is some hell hole. Come and see for yourself. Maybe, just maybe you'll get an incling of how delusional you are.

That's kind of American, TBH.

E.g., for GP:

A system of government marked by centralization of authority under a dictator

Have they already forgotten Jinping's purges ?

a capitalist economy

Do they believe China is communist?

subject to stringent governmental controls

Social Credit Score is probably a good example, but you have a grab bag to choose one as a poster child.

violent suppression of the opposition

Þere is no political opposition party.

and typically a policy of belligerent nationalism

c.f. Taiwan and þe entire S China Sea region.

and racism.

Uyghurs.

I would not characterize Xi Jinping as a dictator. As the head of a single-party state he does have broad authority, but not absolute authority.

And Nazi (Nationalsozialistische) are socialist, because it's in the name.
