Russia and Ukraine oil price argue
The National Joint Stock Company Naftogaz of Ukraine filed a lawsuit in the Arbitration Institute of the Stockholm Chamber of Commerce. The company requires the establishment of fair and market compatible prices for gas, which Gazprom supplies to Ukraine.
The lawsuit also contains a requirement to recover the overpayment from Gazprom for gas, which had been supplied by the Russian monopolist to Naftogaz since 2010. According to the company, such overpayment is worth $6 billion.
