Keith Kellogg, U.S. President Donald Trump's Special Envoy to Ukraine, suggested British and French troops could adopt zones of control in the country, in an interview with The Times newspaper published Saturday. He suggested that a demilitarized zone could be implemented along the existing lines of control in eastern Ukraine, The Times said. To make sure that British, French, Ukrainian and other allied forces do not exchange fire with Russian troops, Kellogg said a buffer zone would be needed. In discussions of partitioning, I was referencing areas or zones of responsibility for an allied force (without U.S. troops). Kellogg said relations between Ukraine and the United States were now "back on track", citing resumed talks over a proposed deal on Ukraine's mineral resources.
