Countries assigned for the AMUN 2023 conference
All countries listed are automatically seated on the Concurrent General Assembly Plenary, the three General Assembly Committees (First, Second and Third). Each delegation is expected to assign a minimum of one representative to each Committee, Council and Commission on which it is seated. Each delegation also has the option to place a second representative on any Committee, Council and Commission on which it is seated (excluding ITU). Each delegation may also choose to place a representative on the International Telecommunication Union. In addition, for specific students, each delegation may also apply to a position on the International Court of Justice and a Reporter position on the International Press Delegation.
