The recent consultations on resolving the #Ukraine conflict, held in #Moscow and #Kiev, were “substantive,” US Secretary of State Marco Rubio said. “I think there’s an opportunity over the next few weeks to develop a roadmap moving forward to restart talks and maybe reach a conclusion there that that's acceptable to both sides because that’s what it’s going to take in order for it to end,” he told reporters. “The United States has always been willing to play the role of a mediator,” Rubio added.
