Oil and the Iranian-Saudi "Cold War"

But, to put it simply, the Islamic Republic won the battle. With strong support from Algeria, Angola, Iraq, and Venezuela, Iran turned back the Saudi initiative for OPEC to raise production quotas. Iran's OPEC governor, Mohammad Ali Khatibi, reported that the Saudis "were very angry" at the outcome. This seems highly plausible, as the Kingdom's long-serving Oil Minister, 'Ali Na'imi, said publicly that the June meeting was "one of the worst meetings we have ever had."
