KIEV, Aug. 8 – Ukraine expects that the Stockholm Arbitration Institute will cancel the "take-or-pay" condition in the contract on the purchase of natural gas signed between national joint-stock company Naftogaz Ukrayiny and OJSC Gazprom, Naftogaz Chairman Andriy Kobolev said.

"We want to lift it [the condition]. In our case we have a strong argument for this. In 2013, Gazprom sold 12 billion cubic meters of gas to another intermediary [Dmytro Firtash's Ostchem] on the Ukrainian market at the lower price… How could we speak about the "take-or-pay" principle for the Ukrainian market when Gazprom offers us one price on this market and the lower price for another dealer?" he said in an interview with Russian publication Vedomosti on Thursday.
