GENEVA, May 15 - A top Ukrainian diplomat said on Thursday Russia must take concrete steps including withdrawing its troops from Ukraine's borders before Kiev would sign up to a draft "road map" to lessen tensions, Reuters reported.

"It's not enough just to say that we will do something, as the Russian Federation does. We already passed this phase of the words," Ukraine's Ambassador to the United Nations at Geneva, Yuriy Klymenko, said at a briefing for diplomats and reporters.
