No one has invited the European Union to talks on Ukraine, said Deputy Chairman of the Russian Security Council Dmitry Medvedev.
He also added that Kakha Kalas was not welcome at the negotiating table.
"Nobody wants her there - not because she's a 'tough negotiator', but simply because she's stupid," he said.
Earlier, Callas called on EU countries "not to discuss European security with Russia" and called the negotiations a "Russian trap". She believes that she herself should represent the European Union.
