The Vienna Convention applies to the representation of states in their relations with any international organization of a universal character and to their representation at conferences convened by or under the auspices of such an organization. This Convention basically extends the principles of the Vienna Convention on Diplomatic Relations with regard to facilities, privileges and immunities of missions to official representatives to international organizations and international conferences. The Organization shall, were necessary, assist the host State in securing the discharge of the obligations of the sending State, its mission and the members of its mission in respect of the privileges and immunities provided for under the present Convention. The United Nations Conference on the Repesentation of States in Their Relations with International Organizations was held at Vienna, Austria, from February 14 to March 14, 1975. By a decision of November 30, 1973, the General Assembly had referred to the Conference draft articles adopted by the International Law Commission in 1971.
