Are you talking about China? If so, I’m afraid they’re communist in name only. They realized many years ago that Marxist economic theory doesn’t work and began to integrate capitalist principles into their economy.

You're kind of incredibly ignorant on China. They're a mostly publicly controlled economy.

The reasoning for a private sector is to prevent economic and technological siege.

Also marxist economic theory is literally just a structured critique of capitalism. It doesn't have anything to say about socialism or communism, that is marx's other works.

De facto, China is a capitalist-fascist state more comparable to WW2 Germany than anything Marx ever came up with.

I would really suggest reading "Economy and class structure of german fascism" and comparing it to the political and economic situation of China. (And actually understand those situations, not just passively absorb ideas from anglophone media) This isn't meant to be a dig, but this level of political illiteracy is embarrassing.

than anything Marx ever came up with.

Have you literally read any book that Marx wrote? (The manifesto is a manifesto, it doesn't count, but I'd also be interested in knowing if you've read that)
