No. Vietnam and China like Russia (and unlike Cuba) have moved to free market economies.
Yes, but what incentivized China, Russia, and Viet Nam to move toward free market economies? Did they do this of their own accord? I don’t think so. It may be precisely because of the proximity of Cuba that a reverse process comes into play. I don’t know. Do you think Cuba will be less open, or more open to free market economy because of recent/pending changes?
This I do know: nothing is as it appears, all things are worthy of careful study, and God wins in the end. Truth and righteousness always prevail. Sometimes the enemy is too stupid to know he is but a pawn in the bigger scheme of things.
