At the talks earlier in May, Ukraine said Russia threatened to accelerate its ground offensive into new regions and made a host of maximalist demands, including that Kyiv cede territory still under its control.
Along with its European allies, Ukraine has been ramping up pressure on Trump to hit Moscow with fresh sanctions — a step he has so far not taken.
"Talks of pauses in pressure or easing of sanctions are perceived in Moscow as a political victory –- and only encourage further attacks and continued disregard for diplomacy," Zelenskyy said Friday on social media.
Russia has meanwhile been pressing its advance on the battlefield, with its forces on Friday claiming to have captured another village in the northeastern Kharkiv region.
