Falih said earlier this month that OPEC was close to agreeing to extend the agreement beyond June, although more talks were still needed with non-OPEC countries that were part of the production deal, Reuters reported.
The Organization of the Petroleum Exporting Countries plus Russia and other producers, an alliance known as OPEC+, have a deal to cut output by 1.2 million barrels per day from Jan.
The pact ends this month and the group meets in coming weeks to decide their next move.
“We are hoping that we will reach consensus to extend our agreement when we meet in two-weeks-time in Vienna,” Falih told reporters on the sideline of a G20 energy and environment ministerial meeting in Karuizawa, northwest of Tokyo.
Asked when the meeting will be held, he said: “Probably the first week of July”.
It was not completely clear whether the agreement would also include OPEC+.
OPEC was set to meet on June 25, followed by talks with its allies led by Russia on June 26. But Russia suggested a date change to July 3 to 4, according to sources within the group.
