UKRAINE – The decision of Ukraine’s Security Service to ban Russian Eurovision contestant Yulia Samoilova from entering Ukraine was right, Ukrainian President Pyotr Poroshenko said during his official visit to Latvia’s capital Riga on Tuesday. Ukraine’s top diplomat says there will be no concessions for Russian singer at Eurovision. “Ukraine allows visiting Crimea only through the administrative border of the Kherson region. The other way is a violation of Ukraine’s law what results in sanctions,” Poroshenko told reporters after a meeting with Latvian President Raimonds Vejonis. According to Poroshenko, the Russian side had known about this, but took a decision to send Samoilova to this year’s Eurovision Song Contest. Ukraine regards this decision as “provocation,” he stressed.
