The UAE has rejected a Saudi-led deal at a meeting of OPEC+, leading to growing discord.
International organization of petroleum-exporting countries
The Organization of the Petroleum Exporting Countries is an intergovernmental organization of 13 countries. Founded on 14 September 1960 in Baghdad by the first five members, it has since 1965 been headquartered in Vienna, Austria, although Austria is not an OPEC member state. As of September 2018, the 13 member countries accounted for an estimated 44 percent of global oil production and 81.5 percent of the world's "proven" oil reserves, giving OPEC a major influence on global oil prices that were previously determined by the so-called "Seven Sisters" grouping of multinational oil companies. A larger group called OPEC+ was formed in late 2016 to have more control on the global crude oil market.
