Trump says that the US have had "good calls" with both Ukraine and Russia today, APA reports citing BBC.
"But it's not easy," he said.
Trump also praised himself for bringing the two sides to the point of discussing negotiations.
"I think we've had some very good results," he said. "Just before I came here I got some pretty good news." Though, he did not provide any further details on what he's referring to.
He again claimed Ukrainian troops are "surrounded" and in "grave danger", without providing further evidence.
"I asked him [Putin] not to kill those soldiers," he added. "We don't want them killed."
