KYIV, May 19 – Ukraine has not been importing natural gas under the contract with Gazprom (Russia) for 2,000 days, since November 26, 2015, purchasing the resource exclusively on the western border of the country.

The reason for Ukraine's refusal to buy gas on its eastern border at the end of 2015 was a price inconsistency.

At the same time, after the Stockholm arbitration revised the contractual formula in the contract between Naftogaz and Gazprom, Ukraine was ready to resume direct imports in the spring of 2018, but the Russian monopoly returned the advance payment of $127.6 million to Naftogaz.
