Whether any countries are truly "socialist" depends on how you define socialism — as strict state control of the economy (like in Marxist-Leninist theory), or just strong public services and government involvement in key sectors.
1. Countries that officially call themselves socialist and are ruled by communist parties include:
* China: Ruled by the Communist Party, but the economy is mostly capitalist with heavy state direction. They call it "socialism with Chinese characteristics."
* Vietnam: Similar to China — one-party state with a mix of socialism and open markets.
* Cuba: Still a centrally planned economy, though it has made some reforms. The government provides free health care and education.
* Laos: Like Vietnam, it is officially socialist but has introduced market reforms.
* North Korea: Technically socialist, but functions more like a totalitarian dictatorship with a highly controlled economy and society.
2. Countries with strong socialist influence or social democratic policies (but not actually socialist states) include:
* Nordic countries (Sweden, Norway, Finland, Denmark, Iceland

These are capitalist democracies with strong social safety nets, universal health care, free or affordable education, strong labor protections, and high taxes.
* France, Germany, and Spain: Have social democratic traditions and strong public sectors, but are still capitalist.
* Bolivia: Ruled by a socialist party (MAS) with some nationalized industries and social programs.
* Venezuela: Calls itself socialist (under the Chavista government), with state control over oil and some key sectors, but the economy has collapsed and the political system is authoritarian.
* Portugal: Governed by a socialist party but operates within a market economy like other EU countries.
3. Most countries around the world today are capitalist, even if they have public health care, education, and other social programs. This includes the United States, Canada, Japan, South Korea, Australia, Brazil, Mexico, and most of Africa. These countries allow private ownership, market competition, and political pluralism.
In short: a few one-party socialist states still exist (mostly in Asia), but the vast majority of countries are capitalist with varying degrees of public services. Many nations have socialist or center-left political parties that influence policy, but that doesn't make the country itself socialist in the traditional sense.
