ST. PETERSBURG, June 16. /TASS/. Terms of gas supply contract with Ukraine will not be revised, Russia’s Energy Minister Alexander Novak said on Thursday on the air with RBC TV Channel.

"Our position remains the same in this aspect. The contract on gas supplies to Ukraine effective until 2019 year-end will not be revised because the parties, Gazprom and Naftogaz, are now having the case in the Stockholm Arbitration Court. Any contract amendments may entail risks and critical financial revisions of prior activity. Therefore the price stipulated by this contract will be effective until the end of contract," the minister said.
