The 33rd ministerial meeting of the OPEC+ alliance will take place in Vienna on Wednesday, marking the first in-person ministerial meeting of the group since March 2020.
The United States added Novak to the "Specially Designated Nationals" list, thus imposing personal sanctions against him.
The organization is expected to discuss possible cutbacks in oil output, another source told Sputnik, suggesting that the members of the alliance may agree on gradually cutting the production.
The source suggests that the size of the production cut at the OPEC+ meeting is still to be agreed upon, but Saudi Arabia and Russia are allegedly pushing for reductions of 1.2-1.5 million barrels per day or more, hoping to implement it in a span several months.
