The WSJ reports,"the three sides held a first, joint meeting last Friday in Warsaw, Poland, to discuss Ukraine's gas debts to Russia—now estimated at more than $3.5 billion—and concerns about disruptions of gas supplies to Europe".
"We're holding these further meetings to find a solution to Ukraine's debts," said Sabine Berger, a European Commission spokeswoman. No further details about the dates or location of the talks were given.
She said the three sides had "until the end of the month to resolve the issue", adding that the commission wasn't worried that Russian gas supplies to Ukraine could be disruptedin the meantime.
Russian Energy Minister Alexander Novak, his Ukrainian counterpart Yury Prodan and the EU's energy chief, Günther Oettinger, said on Friday they would come up with measures by the end of May to address Ukraine's energy debts.
