OPEC+ members should stay the course on decisions ahead of the March 31 OPEC+ meeting, which is expected to uphold the existing agreement to gradually increase oil production, said OPEC Secretary General Mohammad Barkindo.

OPEC+ members must remain vigilant and attentive to ever-changing market conditions, he said.

OPEC+ is likely to stick to plans for a modest increase in oil production in May, several sources close to the talks told Reuters, despite rising prices due to the Ukraine crisis and calls from the US and other countries for more supplies.
