technically yugoslavia was its own country made up of other countries it was also communist so i can see the mistake and during the tito years it was oppose to soviet influence
Mongolia and North Korea were heavily under the influence of China. North VietNam, missing from the list, was aided by the U.S.S.R and even fought against China on occasion. Many other communist countries like Ethiopia, South Yemen, Angola, Grenada, Madagascar, Peru, Somalia, etc. were heavily aided and guided by the U.S.S.R.
