There are very few truly communist countries left in the world. As of right now there are only 5 that openly say they're communist and have some power to back it up.
North Korea: Supposedly communist, more of an oligarchy
China: Capitalist not communist but at least they try by having the communist republic running everything
Cuba: The only successful communist state in the western hemisphere
Laos: Has been communist since 1975 the U.S. was none too pleased
Vietnam: We actually fought a war over this one and lost... horribly I might add
