The Organization of Petroleum Exporting Countries (OPEC) coordinates most of the world’s oil production. The members of OPEC meet to coordinate oil policies and prices. Thirteen countries comprise OPEC: Algeria, Angola, Ecuador, Indonesia, Iran, Iraq, Kuwait, Libya, Nigeria, Qatar, Saudi Arabia, United Arab Emirates, and Venezuela. Though Russia, the United States, and Mexico are also leading petroleum producers, the three countries are not members of OPEC.
