what is the only country that is not a member of the african union
African Union The African Union (AU) is a continental union consisting of all 55 countries on the African continent, extending slightly into Asia via the Sinai Peninsula in Egypt. It was established on 26 May 2001 in Addis Ababa, Ethiopia, and launched on 9 July 2002 in South Africa,[6] with the aim of replacing the Organisation of African Unity (OAU) established on 25 May 1963 in Addis Ababa, with 32 signatory governments. The most important decisions of the AU are made by the Assembly of the African Union, a semi-annual meeting of the heads of state and government of its member states. The AU's secretariat, the African Union Commission, is based in Addis Ababa.
Member states of the United Nations In principle, only sovereign states can become UN members, and currently all UN members are sovereign states. Although five members were not sovereign when they joined the UN, all subsequently became fully independent between 1946 and 1991. Because a state can only be admitted to membership in the UN by the approval of the Security Council and the General Assembly, a number of states that are considered sovereign according to the Montevideo Convention are not members of the UN. This is because the UN does not consider them to possess sovereignty, mainly due to the lack of international recognition or due to opposition from one of the permanent members.
