The Republic of Serbia continued the membership of Serbia and Montenegro in the United Nations, including all organs and organizations of the United Nations system, on the basis of Article 60 of the Constitutional Charter of Serbia and Montenegro, activated by the Declaration of Independence adopted by the National Assembly of Montenegro on 3 June 2006. Accordingly, by a letter dated 3 June 2006, the President of the Republic of Serbia notified the Secretary-General that "membership of the state union of Serbia and Montenegro is continued by the Republic of Serbia in the United Nations, including all organs and organizations of the United Nations system...".
Subsequently, in a letter dated 16 June 2006, the Minister for Foreign Affairs of the Republic of Serbia informed the Secretary-General that "the Republic of Serbia continues to exercise its rights and honour its commitments deriving from international treaties concluded by Serbia and Montenegro. Therefore, the Ministry of Foreign Affairs requests that the Republic of Serbia be considered a party to all international agreements in force, instead of Serbia and Montenegro. Furthermore, the Government of the Republic of Serbia will perform the functions formerly performed by the Council of ministers of the state union of Serbia and Montenegro as depositary for the corresponding multilateral treaties." Moreover, in a letter dated 30 June 2006, the Minister for Foreign Affaires of the Republic of Serbia confirmed that "all treaty actions undertaken by Serbia and Montenegro will continue in force with respect to the Republic of Serbia with effect from 3 June 2006. Therefore, all declarations, reservations and notifications made by Serbia and Montenegro will be maintained by the Republic of Serbia until the Secretary-General, as depositary, is duly notified otherwise."
