MOSCOW (Sputnik) — Naftogaz said in 2014 it wanted to change the 2009 deal with Gazprom to increase the tariff rate for gas transit through its territory. Starting this year, it unilaterally hiked the rate by 1.5 times to $4.5 per 1,000 cubic meters for every hundred kilometers (62 miles).
"It is very strange that despite the current contract, which will be in effect till 2019, the Ukrainian colleagues… unilaterally claim increase of the tariff rate… We work and will continue working in accordance with the contract. We know about arbitration processes in Stockholm, that is why, if we fail to come to the agreement, we will solve these issues in the arbitrary court," Medvedev told reporters.
According to Medvedev, Russia does not refuse to carry out talks and the Ukrainian colleagues have been invited to Moscow to discuss the issue.
