Iran suggested at the OPEC meeting, which failed to come up with an agreement, that ministers delay a decision on raising output by two or three months and then meet again in Iran in September.

The idea was rejected by countries, which wanted an immediate increase in oil output to help control rising prices and spur economic growth, but was supported by Venezuela.

Iran has not yet given up on the idea of holding an emergency meeting before the group meets in Vienna in December.

“It was decided that subsequent to this meeting ... there be a decision made regarding the holding of an extraordinary meeting,” OPEC governor Mohammad Ali Khatibi told the semi-official Mehr news agency on Friday.

“There has not been a time or venue decided for the emergency meeting, but the idea of holding it has not been negated,” he said.
