Slovakia and Ukraine have reached a deal that will allow gas from Central Europe to reach Ukraine via Slovakia. Ukraine has been looking for alternatives to Russian gas, which last year accounted for around a half of its 55bcm consumption.Russia has almost doubled the price of gas for Ukraine, following the toppling of pro-Russian President Viktor Yanukovich in February. Also, Ukraine owes Russian gas firm, Gazprom 2.2 billion dollars for supplies of gas. The two nations are in dispute over that debt and Ukrainian officials are concerned that Gazprom could just cut off the nation's supply of gas.
