Three categories of observer are allowed to attend all or part of the IOC’s sessions, provided they have the prior consent of the Council of Members.
- International organisations and institutions. This includes the United Nations and its organs, in particular the United Nations Conference on Trade and Development (UNCTAD), the United Nations Development Programme (UNDP), the World Health Organisation (WHO), the Food and Agriculture Organisation of the United Nations (FAO), the Joint FAO/WHO Programme of the Codex Alimentarius Commission, the International Labour Organisation (ILO), the United Nations Educational, Scientific and Cultural Organisation (UNESCO) and other specialised UN agencies.
- Intergovernmental, governmental and non-governmental organisations that could provide funding for IOC activities.
- The government of any member or observer State of the United Nations or of one of the organisations mentioned in the first bullet which envisages joining the Agreement.
Recently, the Council of Members took a further step forward in strengthening its relationship with the private sector by authorising the chair of the IOC Advisory Committee on Olive Oil and Table Olives to attend sessions.
