VIENNA—OPEC tentatively agreed to an oil output cut on Dec. 6 but was waiting for a commitment from non-OPEC heavyweight Russia before deciding the exact volumes for a production reduction aimed at propping up crude prices, two sources from the group said.
Russian Energy Minister Alexander Novak flew home from Vienna earlier for talks with President Vladimir Putin in St Petersburg. Novak returns to Austria’s capital for discussions among Saudi-led OPEC and the group’s allies on Dec. 7.
