Though they don't use that word, most of the European nations are socialist for quite a time now. The concept of socialism were founded and nurtured in Europe.
Some European would win over China if there were any rankings for socialist nations.
you should not mix socialism and communism, China is hardly having socialism, which is perfectly nurtured in Scandinavian countries, where state is providing socially responsible actions and freedom
China is an example of mixed communism and capitalism, where is normal to work 50+ hours a week, which Scandinavians are trying to reduce their week to 30 hours, a real progress in life conditions
and most of Europe is near to socialism, where social-democratic parties are in the lead, expect some Eastern European countries, where social-nationalist parties are in the lead
