KYIV, Sept 10 – CEO of Naftogaz Ukrayiny Yuriy Vitrenko has said that the record-high increase in spot prices for gas is linked to the restriction of supplies to Europe by Russia's Gazprom.

"We believe that the price increase that we are seeing on the market now is the result of a de facto special campaign on the part of Gazprom, which simply restricts gas supplies to Europe," he told Interfax-Ukraine on the sidelines of the YES Brainstorming 2021 forum held in Kyiv on Friday.
