Socialism, noun, "a political and economic theory of social organization which advocates that the means of production, distribution, and exchange should be owned or regulated by the community as a whole."

In how many of those states is that actually true? Maybe Cuba (which the US has been trying to overthrow for decades), and Kurdistan (oops guess who was completely abandoned by the US even though they were instrumental in defeating ISIS?), which that page doesn't even mention. The rest are some form of state capitalism. Certainly China is. Unless you think the workers democratically decided that being paid starvation wages to work in electronics factories to make cheap stuff for Americans was a good idea.
