Energy policy has been debated at new talks between Russian and Ukraine.
This is according to a report by the Itar-Tass news agency, which stated that the European Union was also involved in the discussions, which took place last month.
Ukrainian energy minister Yuri Boiko told an energy policy conference earlier this week about the recent talks.
"Such a dialogue will be continued and it's very positive that it began," he said.
"We should begin the dialogue in the three-party format, as every component of our business is important for Europe's energy security."
He added that Ukraine can play a crucial part in any energy policy decisions which are made by the European Union, due to its role as a deliverer of gas supplies from Asia and Russia into central European countries.
This comes shortly after Russian prime minister Vladimir Putin was quoted as saying by Reuters that changes being made to European energy policy amount to "robbery".
