"Transit obligations are being observed [by the Ukrainian side] in full so, naturally, there will be no cataclysms," Yuri Boiko said Monday, RIA Novosti reported.
Russian energy company Gazprom cut natural gas supplies to Ukraine in 2009 because of a contractual dispute. Boiko said his country wasn't satisfied with an agreement that ended the row but was remained committed to its obligations.
The dispute left downstream European consumers in the the cold during the winter of 2009. European consumers have since courted alternative suppliers from the Caspian region to break Russia's grip on the regional energy sector.
Last week, Ukraine last week gave preliminary approval to a shale natural gas deal with U.S. energy company Chevron Corp. Ukrainian Prime Minister Mykola Azarov said there may be enough natural gas in shale to meet the country's needs without imports.
