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. There are banks, there is a stock market, and there is private ownership of the means of production, although all of these are tightly regulated by the state and can be rescinded at any time or for any reason (such as not paying enough bribes).
De facto, China is a capitalist-fascist state more comparable to WW2 Germany than anything Marx ever came up with.
