Ukraine conflict is tough to resolve but certain progress is being observed in its settlement, US special presidential envoy for peace missions Steve Witkoff said, APA reports.
"I sense that there's some break, there's some progress today, but I think it's a tough conflict," he said at a business forum in Miami, Florida.
"I think, we have a lot of work to do with regard to security protocols for Ukraine," the envoy added, pointing out that "there's a lot of discussion that technical teams have to have" in order to hold a high-level meeting.
