Neutral and Non-Aligned European States

Neutral and Non-Aligned European States, sometimes known by abbreviation NN states, was a Cold War era informal grouping of states in Europe which were neither part of NATO nor Warsaw Pact but were either neutral or members of the Non-Aligned Movement. The group brought together neutral countries of Austria, Finland, Sweden and Switzerland on one, and non-aligned SFR Yugoslavia, Cyprus and Malta on the other hand, all of which together shared interest in preservation of their independent non-bloc position with regard to NATO, European Community, Warsaw Pact and the Council for Mutual Economic Assistance.
