Brussels, Belgium (CNN) - New Ukrainian President Petro Poroshenko says peace is possible if Russian President Vladimir Putin is in the right mood.
"Sometimes, the position of Mr. Putin is quite pragmatic, sometimes it is very emotional," Poroshenko told CNN's Christiane Amanpour on Thursday in an exclusive interview, his first broadcast interview since taking over as Ukraine's leader on June 7. "I just try to find out the time when he is more pragmatic than emotional."
He said negotiations with Russian separatists in eastern Ukraine would continue on Friday, the day his unilaterally declared cease-fire expires and the day that he also will sign a cooperation agreement with the European Union that sparked the crisis in his country.
