Volodymyr Zelensky has said he is still “ready to sign” a US-Ukraine minerals deal after leaving the White House without it being agreed.

Ukraine’s president told reporters that despite a fractious meeting with US President Donald Trump last week, he is still willing to have a “constructive dialogue” with the US, but said: “I just want the Ukrainian position to be heard.”

“We want our partners to remember who the aggressor is in this war,” he added.

When relations between the US and Ukraine first became strained over the Trump administration’s handing of peace talks with Russia, the minerals deal was intended as a stepping stone towards further security ties between the two countries.

But after Zelensky, Trump and US Vice-President JD Vance had a heated argument in front of the media in the Oval Office, the Ukrainian leader was told to leave without the deal being signed.

Zelensky’s remarks come as US Treasury Secretary Scott Bessent told the BBC’s US partner CBS News it was “impossible to have an economic deal without a peace deal”.

Bessent said Zelensky had “thrown off the sequencing” of how the minerals deal and peace deal were supposed to play out – instead choosing to “relitigate” discussions in public when they should have taken place in private.

Speaking after a summit of European leaders in London on Sunday, Zelensky said the combative nature of his recent meeting in Washington did not benefit the US or Ukraine as partners, and only really benefited Russian President Vladimir Putin.

However, he said that he would return to the White House if invited.

But he refused to be drawn into talking about about conceding territory to Putin – an option Trump officials have touted as part of a peace deal – or expressing regret in how he had handled the meeting with Trump.

Russia launched a full-scale invasion of Ukraine in February 2022, and currently controls around 20% of Ukrainian territory.

Zelensky was speaking to the media in London following a summit in which world leaders agreed on a four-point plan to work with Ukraine to stop the war and defend it from future Russian aggression.

Among these pledges is for the UK, France and other nations to form a “coalition of the willing” to defend a potential peace agreement in Ukraine.

UK Prime Minister Sir Keir Starmer reiterated that Europe “must do the heavy lifting”, but that any agreement would need US backing.

Asked for his thoughts on the outcome of the summit, Zelensky said the “best security guarantees are a strong Ukrainian army”.

But he added that Europe needed some form of US input, perhaps in the form of air defence and intelligence, in an apparent sign of agreement with Sir Keir.

In an interview with France’s Le Figaro newspaper on the way to the summit, French President Emmanuel Macron was quoted as saying that a month-long truce on striking in the air, on the sea and energy infrastructure was on the table.

During this time, a peace deal could be thrashed out, while the deploying of European troops would occur in a second stage.

Asked by the BBC’s Laura Kuenssberg about these reports, Zelensky joked that he was “aware of everything”.

Zelensky insisted that Ukraine’s relationship with the US will continue and he was “sure that this situation will pass by”, in reference to the fall-out with Trump.

He said that there had been communication between the US and Ukraine since Friday, but “not on my level”.

The Ukrainian leader also said: “The failure of Ukraine would not just mean Putin’s success, it would be a failure for Europe, it would be a failure for the US.”

Following the shouting match in the Oval Office, several leading Republicans backed how the meeting had been handled by Trump and criticised Zelensky.

Senator Lindsey Graham – once a staunch supporter of Ukraine – told reporters that Zelensky “either needs to resign and send somebody over that we can do business with, or he needs to change”.

Asked about these calls to step down in the interest of US-Ukraine relations, Zelensky said that to resign was one thing, but preventing him from running again would require Nato membership.

Ukraine joining the transatlantic military alliance has been a demand of Kyiv since the war began, and forms a key part of the country’s victory plan – though the Trump administration has said this was unlikely.

“I am exchangeable for Nato,” Zelensky told journalists at Stanstead Airport before he left the UK.

“I have said that I am exchanging for Nato membership, then it means I have fulfilled my mission. Nato means I have fulfilled my mission.”

He added that it was “not very democratic” for people from other nations to be deciding who led Ukraine, but said Graham could become Ukrainian and then “his voice will have weight” in deciding who its leader was.
