Finland is well represented in the UN civil service in proportion to its population and belongs to several of its specialised and related agencies. Finnish troops have participated in United Nations peacekeeping activities since 1956, and the Finns continue to be one of the largest per capita contributors of peacekeepers in the world. Finland is an active participant in the Organization for Security and Cooperation in Europe (OSCE) and in early 1995 assumed the co-chairmanship of the OSCE's Minsk Group on the Nagorno-Karabakh conflict.
