Russia has asked Kazakhstan to stand ready to supply it with 100,000 tons of gasoline in case of shortages exacerbated by Ukrainian drone attacks and outages, three industry sources told Reuters.
One of the sources said a deal on using reserves for Russia has already been agreed.
Shyngys Ilyasov, an advisor to Kazakhstan's energy minister, said the energy ministry has not received such a request from its Russian counterpart.
Russian energy ministry did not reply to a request for comment.
