Slovenia became a member of the United Nations on 22 May 1992. With membership of this universal international organisation, it gained the opportunity to directly express its policy on key issues facing the international community and to affirm itself politically as a subject of international law. In 1996, Slovenia joined the East European elective group, and in October 1997 it became a non-permanent member of the Security Council for a period of two years. During this time it also twice presided over the Security Council. This was Slovenia's first active participation in the mechanism of collective security and in decision-making on regional and international issues.
