President of Ukraine Petro Poroshenko said that the U.S., Germany, France and Ukraine do not disagree about adopting road map for implementing the Minsk agreements.

“I can confirm the U.S. administration is in touch with German, French and Ukrainian officials. And we all speak with one voice … We insist that the road map should be approved, that there are exact dates and exact steps, which Russia should take to stop gunfire and withdraw troops,” Poroshenko said in an interview to CNN aired on Sunday evening.

Poroshenko said extending international economic sanctions on Russia is an effective tool for ensuring compliance.
