KYIV, Oct 24 – Naftogaz Ukrayiny hopes the Arbitration Institute of the Stockholm Chamber of Commerce will make a decision regarding supplies of gas by Russia's Gazprom to uncontrolled areas of Donbas in the lawsuit concerning the gas supply contract, Naftogaz Head Andriy Kobolev told reporters Tuesday.

"The issue of gas supplies to Donetsk and Luhansk is subject to the gas supply contract, and it is heard by the Arbitration Institute of the Stockholm Chamber of Commerce. We took a position that without this decision it is impossible to solve the entire lawsuit. I cannot give more details," he said.
