The US leader would not rule out secondary tariffs on Russia if the peace process stalls

US President Donald Trump has said his Russian counterpart, Vladimir Putin, would honor his part of a potential peace agreement on the Ukraine conflict. At the same time, Trump warned Kiev against backing out of a rare-earth minerals deal with the US.

Speaking to reporters on Monday, the US leader repeated that he aims to end the conflict between Russia and Ukraine as soon as possible, adding that he "want[s] to make sure that he [Putin] follows through" on any peace deal.

"I think he will. I don't want to go secondary tariffs on his oil, but I think it's something I would do if I thought he wasn't doing the job," Trump stated.

He expressed hope that Ukraine's Vladimir Zelensky would also uphold his end of the bargain, but rebuked him for apparent attempts to renegotiate the rare-earths deal which would grant the US access to Ukraine's mineral deposits. While Trump has portrayed the deal as a way for Ukraine to pay back past US assistance, Zelensky has insisted that Kiev owes Washington nothing.

"We made a deal for rare earths. It was all done. They're now saying, 'Well, I'll only do that deal if we get into NATO or something to that effect,'" Trump said. He insisted that NATO membership for Ukraine was "never... discussed," suggesting that the issue was the likely reason for the escalation of hostilities between Moscow and Kiev in 2022.

Trump earlier threatened Zelensky with "big problems" if he rejects the rare-earths deal. The Ukrainian leader, however, has said that "the framework [of the agreement] has been changed" from what he was willing to sign during a meeting with Trump in late February.

On that occasion, the pair's White House meeting turned into a heated clash, with Trump accusing Zelensky of ingratitude and "playing with World War III" over what he perceived as reluctance to make a deal with Russia.

At the same time, Trump said on Sunday that he was "very angry" with Putin's proposal to place Ukraine under a temporary UN-led administration to organize new elections. Russia has long insisted that Zelensky is an "illegitimate" leader, given that his presidential term expired in May 2024.

Kremlin spokesman Dmitry Peskov has said Moscow and Washington are exploring several ideas aimed at resolving the Ukraine conflict, adding that Putin is open to any contact with Trump. Russia maintains that the conflict could be settled if Ukraine commits to bloc neutrality and demilitarization, and recognizes the territorial reality on the ground.
