"There is nothing, not even a hint, formal or unofficial negotiations," Reuters quoted Vitrenko as saying.
According to him, the Russian side does not want to start a discussion.
He also added that the participation of Naftogaz and the Ukrainian GTS Operator in the certification of the Nord Stream 2 gas pipeline does not give Kiev the opportunity to stop this process.
Earlier, the President of Ukraine Volodymyr Zelensky said that there is no talk of direct purchases of gas in Russia at the moment.
