Qatari Oil Minister Mr Abdullah al-Attiyah said today there was a strong movement within OPEC to cut output to shore up sagging oil prices.
A Gulf source last week said momentum was starting to build within the producers' group for a reduction of between 700,000 barrels per day (bpd) to one million bpd.
But the Qatari oil minister declined to discuss volumes involved. "Now we are still in consultations between ourselves - OPEC and non-OPEC - so I cannot give any figure," he said.
The minister said a potential supply curb, which would be the group's fourth this year, could be agreed at any moment.
