Ukrainian President Volodymyr Zelensky said he had a "very good" meeting with US President Donald Trump in Davos on Thursday.
"We spoke about documents and about air defense," Zelensky told reporters briefly without elaborating before addressing the World Economic Forum in the Swiss ski resort.
Zelenskiy also said he discussed progress on peace talks.
"We discussed the work of our teams, and practically every there are meetings or communication," Zelenskiy wrote on X, adding that the documents being negotiated by Kyiv and Washington were "now even better prepared".
"Our previous meeting with President Trump helped strengthen the protection of our skies, and I hope that this time we will reinforce it further as well."
