Novak's remarks came after reports that the new variant Omicron, considered by the World Health Organization to be "a variant of concern," had been detected in several countries, prompting big economies to respond with stricter restrictions.
Novak said OPEC+ partners had not requested a revision of their short-term production plan, according to Russian news agency TASS.
The OPEC+ group is scheduled to hold a meeting on Thursday after which an announcement of the final decision on January's production volume will be made following technical discussions.
After South African scientists said last week that they had discovered the highly mutated variant, it spread from South Africa to several countries including Australia, Belgium, Botswana, Britain, Denmark, Germany, Hong Kong, Israel, Italy, the Netherlands, France and Canada.
Several countries around the world have now banned flights from over half a dozen southern African nations, including South Africa, Namibia, Botswana, Zimbabwe, Mozambique, Lesotho and Eswatini over fears of the new variant.
