The European Union will host the next round of gas talks between Ukraine and Russia on April 14 in Berlin, the European Commission said on Tuesday. Ukraine and Russia said last month that they would seek to negotiate a deal that would ensure natural-gas deliveries to Ukraine and the European Union until a dispute over unpaid bills has been settled. The first round of those talks took place in Brussels on March 20. The talks would be about the price of Russia’s gas exports, the amount Ukraine needs to import for gas storage as well as financial support to Ukraine, said a spokeswoman for the commission, the EU’s executive arm. Last week, Russia and Ukraine extended an interim gas deal through the end of the second quarter, the largest Ukrainian energy company Naftogaz said, giving the sides time to negotiate a longer-term deal.
