"We will have a meeting with Sefcovic in Astana in June on the sidelines of EXPO," Novak said.
The Russian energy minister noted that the issue of gas supplies to Ukraine might be raised within the talks.
"This issue is always on the agenda. Usually, it is initiated by the Ukrainian side or the European Commission. So, if it is raised, we will be ready to discuss it, however, we have a contract, and Gazprom will supply gas in accordance with prepayment," Novak said.
Novak added that Russia wanted to obtain legal guarantees from the European Commission that Kiev would not fine Gazprom within the anti-trust case, in accordance with which Kiev wanted to recover the $6.4-billion fine from Gazprom over alleged abuse of monopoly position on the gas transit market within the period from 2009 to 2015.
