KYIV, Sept 13 – Ukraine has not been buying Russian gas for a long time, and the country's gas transmission system can operate without its transit, Yuriy Vitrenko, CEO of Naftogaz Ukrayiny, told Interfax-Ukraine on the sidelines of the 17th YES Annual Meeting held by the Victor Pinchuk Foundation at the end of last week in Kyiv.

"The president directly says that the main risks are military risks. If there is deterioration in certain sectors of the front, then, according to our experience, we cannot help in any way. People should be prepared for everything, for the fact that while fighting lasts for a month or two, they could survive even without heating," Vitrenko said.
