China IS officially communist, but they've veered a long way from what used to be called "state socialism" with the fully planned economy, and they're much more capitalistic these days, but with a lot of state supervision that cuts into what we would consider to be essential rights (privacy, free speech, assembly, et cetera).
It's not a paradise, but if you remember where they were in 1900, or in 1949, it's a pretty remarkable resurgence.
