Ukrainian President Volodymyr Zelenskiy said on Monday that concessions to Russia would not persuade it to stop fighting in Ukraine and that there was need to ramp up pressure on the Kremlin.
"Russia is dragging out the war, and therefore it deserves stronger global pressure. Russia refuses to stop the killings, and therefore must not receive any rewards or benefits," he wrote on X.
"And this is not just a moral position – it is a rational one. Concessions do not persuade a killer."
Zelenskiy made the remarks days before US President Donald Trump and his Russian counterpart Vladimir Putin are due to meet in Alaska.
