Zanganaeh said at the OPEC plenary session in Isfahan in central Iran. Sabah told Arab reporters at the conference that the OPEC decision to increase production for the fourth time in less than a year was a signal that the cartel was not interested in a price race with consumers. "Despite the OPEC decision to increase the quota, the prices will eventually be influenced by market speculations and geopolitical developments rather than the OPEC mechanism," said Hussein Kazempur- Ardebili, the OPEC governor for Iran.
