This isn’t true, though. Socialism is a transitional status towards the goal of Communism, states that are pushing forwards on that goal, or “on the Socialist road,” play a progressive role, while Capitalist countries take a regressive role. Socialist countries indeed exist in the context of a world economy dominated by Capitalism, but are moving against that.

I call many countries Socialist, like the PRC, Cuba, Laos, Vietnam, former USSR, etc.
