European Commission President Jose Manuel Barroso warned Russia on Saturday that the EU was ready to defend its principles in the confrontation over Ukraine and called for a political solution before the crisis reached a "point of no-return".
"Russia should not underestimate the European Union's will and resolve to stand by its principles and values," Barroso told a joint news conference in Brussels with Ukrainian President Petro Poroshenko, Reuters reported.
He said it was not too late for a political solution.
