OPEC waiting for Russia before deciding level of oil cut

VIENNA (Reuters) - OPEC has made a planned cut in oil output effectively conditional on the contribution from non-OPEC producer Russia, OPEC delegates said on Thursday as the group gathered for a meeting in Vienna.

Five delegates said the group was waiting for news from Russia as Energy Minister Alexander Novak flew back from Vienna on Wednesday for a possible meeting with President Vladimir Putin.
