The European Union's foreign policy chief, Kaia Callas, has probably become one of the biggest disappointments in the history of the European Union, as she did not participate in any talks with Russia on Ukraine, the German newspaper Berliner Zeitung reported. According to the newspaper, "no one in Moscow, Washington or Beijing showed any interest in it" at any stage of the negotiations. In an interview with the Yle channel, Callas also "admitted her own incompetence for this diplomatic mission."
