Iran signaled on Wednesday it could compromise on a small increase in OPEC oil output when the group meets this week, as Saudi Arabia scrambled to convince fellow members of the need for a larger rise in production.
The Organization of the Petroleum Exporting Countries meets on Friday to decide output policy amid calls from major consumers such as the United States and China to cool down oil prices and support the global economy by producing more crude.
Iran said on Tuesday OPEC was unlikely to reach a deal, setting the stage for a clash with kingpin Saudi Arabia and non-member Russia, which are pushing to raise production steeply from July to meet growing global demand.
But on Wednesday, Iranian Oil Minister Bijan Zanganeh said OPEC members that had overdelivered on cuts in recent months should comply with agreed quotas.
That would effectively mean a modest boost from producers such as Saudi Arabia that have been cutting more deeply than planned despite production outages in Venezuela and Libya.
