You're reading: Ukraine threatens Russia with lawsuit over gas

(AP)— Ukraine's prime minister says it may take Russia to court if Moscow doesn't agree to a lower price in negotiations for natural gas.

Mykola Azarov said Dec. 29 on his Facebook page that settling the matter with Russia in international arbitration courts is “the only possibility” if a compromise is not reached.

Kyiv and Moscow have been locked in tense negotiations over the price of Russian natural gas. Ukraine is currently paying about $400 per 1,000 cubic meters of gas, but wants to pay $250. The talks have so far failed to produce a deal and a new round is set for mid-January.

Russia has said it is willing to lower the price if Ukraine gives up control over its strategic pipeline network and joins a Moscow-led customs union. So far Kyiv has resisted those offers.
