National joint-stock company Naftogaz Ukrainy will be ready to resume gas purchases from Russia's Gazprom after the implementation of the decision of the Arbitration Institute of the Stockholm Chamber of Commerce on the relevant contract signed by the two companies, Naftogaz Head Adnriy Kobolev said at a press conference in Brussels on Thursday.

"After the first separate ruling of the Stockholm Arbitration on the supply case the price should be revised, and as soon as Gazprom complies with the decision of the tribunal we are prepared to start buying gas from them," he said.

Kobolev said that the company does not know for sure how long it would take for Gazprom to execute the decision of the tribunal, and Naftogaz does not expect that gas purchases would resume this year.
