Ukrainian President Volodymyr Zelenskiy has invited US President Joe Biden to visit Ukraine soon.
The invitation was issued on Sunday when the two leaders spoke by phone, a statement from Mr Zelenskiy’s office said.
Reuters reports that tensions have been rising for weeks over Russia’s troop build-up near Ukraine, with Washington saying an invasion could happen anytime.
Moscow denies planning any attack against its pro-Western neighbour.
“I’m convinced that your arrival in Kyiv in the coming days, which are crucial for stabilising the situation, will be a powerful signal and contribute to de-escalation,” the presidential office quoted Mr Zelenskiy as telling Mr Biden.
The White House declined to comment on the invitation.
CNN cited an unnamed Ukrainian official saying there was no positive response from the US President to the idea.
The Ukrainian readout of the call had President Zelenskiy saying Ukraine understood the threats it faced and was ready to face any scenario, while thanking the US for its support.
“We expect it to among other things help prevent the spread of a mood of panic,” he was quoted as saying.
Mr Zelenskiy has voiced frustrations with some of the dire assessments of a looming war.
Analysts say such warnings have taken their toll on the economy, piling pressure on the national currency.
