Russia and Ukraine “are still far apart” on a deal to ensure stable natural-gas deliveries to Ukraine and the European Union over the winter, the EU’s energy czar said Tuesday. The statement from the EU’s vice president for the energy union, Maros Sefcovic, came after the energy ministers from both sides met in Vienna, along with the chief executives of their gas companies, Russia’s OAO Gazprom and Ukraine’s OAO Naftogaz. The EU gets about one-third of its gas from Russia and about half of that is transported through Ukraine. But the conflict in eastern Ukraine and the broader standoff between Moscow and Kiev has put these deliveries in doubt. “As the meeting has shown today, the parties are still far apart,” Mr. Sefcovic said. “We have agreed that the [European] Commission will put forward ideas to prepare next steps so that the next consultation could take place.”
