The Ukrainian government approved a bill on Friday to split the national energy company Naftogaz into production and transportation divisions and prohibit rental or privatization of the gas transportation system.
Naftogaz should be split according to the provisions of the EU Third Energy Package, which requires the separation of energy production, transportation and sales, as Ukraine is a member of the European Energy Communit, Ukrainian Deputy Minister of Energy and Mines Vladimir Makukha said.
Russia had previously proposed setting up a joint venture between Naftogaz and Gazprom, to run Ukraine's gas transit system, as part of a settlement of its gas price dispute with Moscow.
The two countries have been embroiled in a long-running dispute over the price and volume of Russian gas purchased by Ukraine. Kiev insists the current price is too high.
In late February Ukrainian Prime Minister Mykola Azarov said Moscow had sent a new gas proposal to Kiev stipulating a 10 percent discount in the price of gas, which Ukraine was considering.
Kiev imported over 1.8 billion cubic meters of Russian gas in January 2012, while in February it had to increase purchases to 3.1 billion cu m due to the severe cold. The annual average Russian gas price for Ukraine for this year stands at $416 per 1,000 cu m.
Ukraine claims it would be cheaper to buy gas from Germany, and has begun exploring other sources of supply.
