From the article:
Iranian oil minister Bijan Namdar Zangeneh said the pressure to boost production was related to November's upcoming presidential election in the United States.
"We had the situation like it four years ago where we were very close to another presidential election in the United States," he said. "Every day we are going to be closer to this date, we will have some pressure ... to do something and to satisfy their voters."
In his book "Plan of Attack," journalist Bob Woodward reported the Bush administration had been assured Saudi Arabia would increase production to reduce oil prices to help the U.S. economy in the months before the election.
Prince Bandar bin Sultan, the Saudi ambassador to the United States, has said there were no secret deals to control oil prices.
I'd be willing to bet that there is a relation... how about you?
