Socialism

I would not therefore say that these countries are an example of communism

I don't think anyone is claiming that either of those countries had achieved communism. They have achieved (to varying degrees) economic socialism, i.e. public ownership of capital. If we define capitalism as a system under which capital is privately owned, then they are not "differently managed capitalism", at least if you believe that the state there has some degree of democracy and is not completely authoritarian (in which case it could be argued that it's just capitalism but with a state monopoly on every industry). The truth of course lies somewhere in between (as all of those examples have/had private ownership of capital, and are not entirely democratic), but I would say that their system seems to be generally working better for them than nearly-pure capitalism does for other countries.
