US President Donald Trump is considering ideas such as a "tariff-free zone" for Ukraine to boost its economy as Washington remains hopeful it will help end Russia's all-out war in Ukraine, US envoy Steve Witkoff said in Davos on Thursday.
"The president has talked about a tariff-free zone from Ukraine that I think would be game-changing," Witkoff said at the Ukrainian Breakfast on the sidelines of the World Economic Forum in the Swiss Alps resort town.
