I think there might be one going on in a section of India at the moment, but the problem comes with defining what Communism is. Is communism when there is absolutely no Capitalism? Because, probably not, no. Is Communism when a majority of goods and services are publicly owned/payed for? Then maybe, but I think there was actually a period where France was beating the USSR for General Government Public Expenditures as a percent of GDP. I know fuck all about modern day data on the subject.
