On Sunday 10 October 2010, a new status of the Netherlands Antilles came into effect within the Kingdom of the Netherlands, by which the country-status land of the Netherlands Antilles ceased to exist. Under the new status, Curacao and Sint Maarten become countries (enjoying internal self-government within the Kingdom), joining Aruba, which gained similar status in 1986.

^ 2.02.1The former Socialist Federal Republic of Yugoslavia (SFRY) became a Member State on 31 March 1950. The participation of Yugoslavia in meetings of governing bodies and conferences of UNESCO was suspended following Resolution 47/1 adopted by the General Assembly of the United Nations on 22 September 1992, which stated that the Federal Republic of Yugoslavia (Serbia and Montenegro) could not continue automatically the membership of the former SFRY. Accordingly, the Federal Republic of Yugoslavia, which became a Member State on 20 December 2000, could not automatically succeed the former SFRY as a member of the Organization. Following the adoption of the Constitutional Charter of Serbia and Montenegro by the Assembly of the Federal Republic of Yugoslavia on 4 February 2003, the name of the State of the Federal Republic of Yugoslavia has been changed to "Serbia and Montenegro". Further to the Declaration of Independence adopted by the Parliament of Montenegro on 3 June 2006, UNESCO has been informed that the membership of the State Union Serbia and Montenegro in UNESCO is continued by the Republic of Serbia on the basis of Article 60 of the Constitutional Charter of Serbia and Montenegro.
