"Quite a large number of OPEC and non-OPEC countries are involved in the GECF, so we will have the opportunity to speak on this subject, because usually those who produce oil, also produce gas. Therefore, they are in general the same countries," Novak told reporters.
"If there will be ministers there, then, of course, we will hold bilateral meetings," the minister added.
The OPEC countries are set to finalize the agreement on oil output freeze at the OPEC summit in Vienna on November 30. The move has been driven by plunging oil prices and an oversupply in the global energy market.
