On Friday night, during what the participants thought were private talks, Venezuela's oil minister Venezuela Rafael Ramirez and his Iranian counterpart Gholamhossein Nozari, argued that pricing - and selling - oil using the crippled dollar was damaging the cartel.
They said Opec should formally express its concern about the weakness of the dollar when the cartel makes its official declaration at the close of the summit today. But the Saudis, the world's largest oil producers and de facto head of Opec, vetoed the proposal. Saud al-Faisal, the Saudi foreign minister, warned that even the mere mention to journalists of the fact that leaders were discussing the weak dollar would cause the US currency to plummet.
Unfortunately his words and those of everyone at the meeting were being broadcast via a live television feed to a group of astonished reporters. 'I couldn't believe it,' said one who was there. 'When I realised they didn't know they were being broadcast live, I frantically started taking notes.'
