The Organisation of Petroleum Exporting Countries, or OPEC in short, was established at the conference held in Baghdad in 1960 for the regulation of oil prices by petroleum exporting countries. Initially, Iran, Iraq, Kuwait, Saudi Arabia and Venezuela joined the organisation.

These five countries were followed by Qatar, (1961), Indonesia (1962), Libya (1962), the United Arab Emirates (1967), Algeria (1969), Nigeria (1971), Ecuador (1973-1992), Gabon (1975-1994), Angola (2007) and Equatorial Guinea (2017).

The headquarters of the organisation has been located in Vienna, Austria, since 1965. Currently, there are 13 members of OPEC, which are Algeria, Angola, Congo, Equatorial Guinea, Gabon, Iran, Iraq, Kuwait, Libya, Nigeria, Saudi Arabia, the United Arab Emirates and Venezuela.

Non-OPEC countries (Azerbaijan, Bahrain, Brunei, Kazakhstan, Malaysia, Mexico, Oman, Russia, Sudan and South Sudan) closely cooperate with the organisation in the 'OPEC Plus' format. The main goal of OPEC Plus cooperation is to reach a consensus on demand and supply in global oil markets.

The cooperation of Azerbaijan with OPEC became more active with its participation in the organisation's meetings with an observer status. An assembly of the member states of the Organization of Petroleum Exporting Countries (OPEC) and non-OPEC countries that produce oil was held in Doha, Qatar, on April 17, 2016, to regulate oil prices in the global energy market.
