LIMA: A gathering of Russian oil firms and President Vladimir Putin that had been scheduled for Nov 23, a week before an Organisation of the Petroleum Exporting Countries (OPEC) meeting in Vienna, has been postponed, Kremlin spokesman Dmitry Peskov told Reuters.

Two energy industry sources told Reuters earlier on Monday that the meeting, which was expected to discuss possible output curbs, had been delayed until Dec 19.

"The commission was postponed as the agenda is still being worked out. Work with Russian oil companies is being regularly carried out by the energy ministry. There are no separate meetings scheduled by the president," Peskov said.
