BRUSSELS, May 19 - Europe's Energy Commissioner said on Monday progress had been made in the gas price dispute between Russia and Ukraine after talks with Russia's energy minister and Gazprom and said a fresh round of negotiations was scheduled for May 26, Reuters reported.

Russian President Vladimir Putin has urged EU leaders to do more to help Ukraine through its economic crisis and resolve the standoff over gas. He has threatened to cut exports if Kiev fails to pay in advance for June deliveries.
