What do you mean by "pure communist country"? You don't know what the words you're using mean. Communism is not a system that can exist within one country, it's a state of the entire globe not having classes, states, or borders. "Communist country" is an oxymoron unless you mean "country ruled by a Communist party" which China objectively is.

China is a socialist market economy. The majority of the economy is under the state's control, and the public has democratic control over the state, so they are free to chart their own path and decide where their economy is headed. In contrast, under capitalism, if the market decides that building more housing and providing healthcare is not profitable, the people must just accept it. See the difference?

Cuba may have a good healthcare system, but sorry if I stick to my capitalistic Europe.

I don't know where in Europe you live, but chances are, conditions in your country are only acceptable because Europe built its wealth by exploiting countries like Cuba. Cuba taking its destiny into its own hands and improving conditions for their people should be applauded, not treated like it's insignificant.
