Russia will not send gas through Ukraine next year, predicts Yuriy Vitrenko, managing director of Naftogaz. “When Nord Stream 2 is finished this year, there will be no need to use the Ukrainian gas transit system,” Vitrenko told a packed conference on future Ukraine’s gas pipeline in Brussels on Tuesday. “And then Ukraine will lose approximately 4% of GDP,” he said, referring to the loss of $2.5 billion a year in gas transit revenues paid by Gazprom.
