"The contact itself serves (as) deterrence and de-escalation," Kuleba said in written remarks about Tuesday's call. "We appreciate the crucial diplomatic engagement of the U.S. in efforts to bring Russia back to the table of negotiations," Kuleba said.
The top diplomat is convinced that during the talks, Putin received a very clear and strong signal over the Russia-driven escalation along the border of Ukraine and in the region.
