BRUSSELS, Jan 12 (Reuters) - All involved parties have signed an agreement to resolve a dispute over Russian gas supplies to Europe via Ukraine, Gazprom's deputy chief executive Alexander Medvedev said on Monday. "The document has been finally signed," Medvedev told a news conference in Brussels.
"If everything goes without problem, most likely in the nearest future we will start pumping the first quantities of gas," he said. (Reporting by David Brunnstrom, writing by Jeremy Smith)
