Kazakhstan’s Energy Minister said he has not yet decided whether to attend the meeting of OPEC members and other oil producers in Vienna.
Kanat Bozumbayev said his country, along with Russia, Azerbaijan and Mexico, was waiting for members of OPEC to agree among themselves proposed output cuts.
Details have not yet been agreed upon.
Iraq and others, such as Libya and Nigeria, have asked for exemptions, while non-OPEC member Russia and top exporter Saudi Arabia have said markets would rebalance even without a cut.
OPEC experts ended a meeting earlier this week without agreeing details on how much individual countries would cut in the output reduction plan to be presented to an OPEC ministerial gathering tomorrow.
