Ukrainian leader Mr Zelensky, who is expected to meet US vice-president JD Vance in Munich on Friday, appealed to western allies to stand firm and hold Russia accountable.
Mr Trump, who spoke with Mr Putin before a phone call with Mr Zelensky, said on Thursday that Kyiv would have a seat at the table in any discussions.
That meeting saw US defence secretary Pete Hegseth announce America was no longer “primarily focused” on guaranteeing European security, leading to calls from some European capitals for greater spending on defence.
Britain and other European allies have said that Ukraine’s voice must be at the heart of any peace talks as the West reels from Mr Trump’s telephone conversation with his Russian counterpart on Wednesday.
The UK is working to seize the “crucial opportunity” of negotiations to end the Ukraine war, a Cabinet minister has said as global leaders gather on fragile diplomatic terms for a major security summit in Munich.
