The upcoming summit between President Donald Trump and his counterpart Vladimir Putin is being used by the Kremlin to divide the U.S. from Europe over the war in Ukraine, according to analysis.

U.S. President Donald Trump said on Monday that both Ukraine and Russia would have to cede land to each other to end the war and that his talks with Russian President Vladimir Putin would be aimed at taking the temperature on a possible deal.

Ukrainian President Volodymyr Zelensky quickly denounced the idea of giving up territory to Russia in a video address on Saturday, vowing that Ukraine would not “gift their land to the occupier” and warning that any peace talks that didn’t involve Kyiv would “bring nothing.”
