The Organization which has mainly economic matters as its objectives is the Organization of Petroleum Exporting Countries (OPEC). OPEC is an intergovernmental organization founded in 1960, which consists of 14 member countries that are primarily oil-producing nations. The main objective of OPEC is to coordinate and unify the petroleum policies of its member countries, in order to secure fair and stable prices for petroleum producers and a regular supply for consumers. OPEC seeks to promote international cooperation in the petroleum industry, to ensure that petroleum resources are managed in a sustainable manner, and to contribute to the economic growth and development of its member countries. OPEC is primarily concerned with economic matters related to the petroleum industry and is not a general-purpose international organization like the United Nations Organization or the League of Nations.
