In an extraordinary acrimonious meeting that was broadcast live on Friday, Trump accused Zelenskiy of being ungrateful for US aid, of showing disrespect to his country and of risking World War Three, casting doubt on Washington's ongoing support for Ukraine.
Zelenskiy, talking to reporters after a summit with European leaders in London on Sunday, said he did not think the US would stop its assistance to Ukraine, because as "leaders of the civilised world" they would not want to help Russian President Vladimir Putin.
However, Zelenskiy says he remains prepared for any challenges that may arise.
"As regards to salvaging the relationship, I think our relationship will continue," he told reporters via a translator after the London meeting.
But he added: "I do not think it's right when such discussions are totally open ... The format of what happened, I don't think it brought something positive or additional to us as partners".
Zelenskiy added he remains ready to sign the proposed minerals deal with the United States, and believes the US is ready as well.Â
Earlier European leaders concluded the summit indicating they wanted to be part of Europe's planned "coalition of the willing" to help Ukraine.
"On the coalition of the willing, yes, a number of countries indicated today that they want to be part of the plan that we are developing," UK Prime Minister Keir Starmer told a news conference following the meeting.
"I'll leave them to make their own statements about exactly how they want to make that contribution but we've been able to move that forward," he said.
"I accept, without criticism and with respect, the position of other countries that may not feel that they want to contribute in that way but I strongly feel that unless some move forward, we will stay in the position we're in and not be able to move forward."
Starmer urged European leaders to join the so-called "coalition of the willing" alongside France and the UK, aimed at keeping the peace if the Ukraine war is brought to a negotiated end.
The UK prime minister said the leaders had agreed to "meet again very soon" to keep up work on the plans.
"We are at a crossroads in history today," he said.
"This is not a moment for more talk. It's time to act. Time to step up and lead, and to unite, around a new plan for a just and enduring peace."
Starmer announced a 1.6 billion pound ($A3.2 billion) deal which would allow Ukraine to purchase 5000 air-defence missiles using export finance, following the gathering at Lancaster House in central London.
Zelenskiy posted on X the summit had convinced him that European unity was "at an exceptionally high level, one that has not been seen in a long time".
NATO Secretary General Mark Rutte said that some European leaders had privately set out new plans on military spending during the London meeting but declined to give details.
"Today at the table I heard new announcements, and I'm not going to announce them to you, because they should do this. But this was very good news that more European countries will ramp up defence spending," Rutte told reporters outside the meeting on Sunday.
Starmer urged European leaders to step up their defence efforts to not only help secure peace in Ukraine but stability across the continent at a summit staged as a show of support for Zelenskiy.
Just two days after a contentious Oval Office exchange the Ukrainian leader was welcomed in London by world leaders, who hugged him in turn, and pledged their backing.
Starmer said Europe needed to meet a once-in-a-generation challenge.
"Getting a good outcome for Ukraine is not just a matter of right and wrong, it is vital for the security of every nation here and many others, too," Starmer said at the beginning of the meeting flanked by Zelenskiy and French President Emmanuel Macron.
"Today's meeting is to unite to discuss how to deliver a just and enduring peace together and to make sure Ukraine can defend and protect against any future Russian attack."
Trying to revive hope for peace in Ukraine, Starmer said urgent talks with Trump, Zelenskiy and Macron over the weekend had cemented the idea that a "coalition of the willing" in Europe would need to move quickly to come up with a peace plan to be presented to the United States.
Polish Prime Minister Donald Tusk, who also attended the summit, said "Europe has woken up".
After the meeting ended, he wrote on X in Polish that the European Union, the United Kingdom, Norway and Turkey now "all speak with one voice about aiding Ukraine, the need for close transatlantic co-operation, and strengthening the eastern border".
European Commission President Ursula von der Leyen said she will present next week a plan to "rearm Europe" to bolster the European Union's security.
