Yeah, this is confusing. A short history lesson: communism in Eastern Europe fell apart in 1989 or maybe 1990, when the Berlin Wall came down. All the eastern European countries were freed. Ain't no such thing over there anymore. Russia's troubles are from a different source: a ton of mineral wealth, like oil and natural gas, that distorts the economy towards commodities. Not entirely of course; not nearly as bad as Saudi Arabia, for instance. Still, oil can be a curse. China never had an outright overthrow, they just sort of decided to have, I suppose, "capitalism with Chinese characteristics", or something.
