From 1999 to 2001, Ukraine served as a non-permanent member of the UN Security Council. Historically, Soviet Ukraine joined the United Nations in 1945 as one of the original members following a Western compromise with the Soviet Union, which had asked for seats for all 15 of its union republics. Ukraine has consistently supported peaceful, negotiated settlements to disputes. It has participated in the quadripartite talks on the conflict in Moldova and promoted a peaceful resolution to conflict in the post-Soviet state of Georgia. Ukraine also has made a substantial contribution to UN peacekeeping operations since 1992.
