The United States International Telecommunication Advisory Committee (ITAC) advises the Department of State in the preparation of U.S. positions for meetings of international treaty organizations, develops and coordinates proposed contributions to international meetings as U.S. contributions, and advises the Department on other matters to be undertaken by the U.S. at these international meetings. The international meetings addressed by the ITAC are those of the International Telecommunication Union, the Inter-American Telecommunication Commission (CITEL) of the Organization of American States, the Organization for Economic Cooperation and Development (OECD) and the Asia-Pacific Economic Cooperation (APEC).
