How does a nation become a member of opec?

To become a member of the Organization of the Petroleum Exporting Countries (OPEC), a nation must meet specific criteria, including having a significant net export of crude oil and being a developing country. The interested nation must also submit a formal application for membership, which OPEC's current member states review. If the application is approved, the nation must then ratify the OPEC Statute and commit to the organization's agreements and decisions. Final acceptance requires consensus among existing members.
