The Organization of Petroleum Exporting Countries (OPEC) was formed in September of 1960 with five founding members: Iran, Iraq, Kuwait, Saudi Arabia and Venezuela. Since then its membership has risen to include Qatar (1961), Libya (1962), the United Arab Emirates (1967), Algeria (1969), Nigeria (1971), Ecuador (1973) and Angola (2007).

Indonesia joined in 1962 and suspended its membership in 2009. Gabon was added in 1975 and terminated its membership in 1995. Ecuador suspended its membership in 1995 and resumed it in 2007.

The five founding members of the cartel must all agree on the admission of new members, giving any of the five veto power on expanding the organization. New members must also be approved by three-quarters of the other full members of the group. The cartel’s rules also allow for associate members, countries that do not qualify for full membership but that may be admitted under special conditions. There are currently no associate members of OPEC.
