Russia said Monday its gas exports plummeted by 25 percent in 2022 after the Ukraine conflict brought turmoil to Moscow's ties with key buyers in Europe.

Deputy Prime Minister Alexander Novak attributed the fall in gas exports to "the refusal of European countries to buy Russian gas, as well as sabotage on the Nord Stream 1 and Nord Stream 2 gas pipelines." Writing in the specialized journal "Energy Policy," Novak also said Russian oil exports had increased 7.6 percent over the same period.
