Ukrainian President Volodymyr Zelenskyy said Tuesday that the Oval Office blowup with U.S. counterpart Donald Trump last week was “regrettable,” adding that he stands ready to work under Trump’s “strong leadership” to get a lasting peace.

Zelenskyy’s remarks — an apparent attempt to placate Trump — came in a social media post on X, hours after the White House announced a pause in military aid to Ukraine that is critical to fighting Russia’s invasion.

But later during his nightly address, Zelenskyy indicated that Ukraine didn’t receive direct notification from the U.S. that aid had been cut, and was seeking confirmation.

“I have instructed Ukraine’s Minister of Defense, the heads of our intelligence agencies, and our diplomats to contact their counterparts in the United States and obtain official information. People should not have to guess,” he said.

“Ukraine and America deserve a respectful dialogue and a clear position from one another. Especially when it comes to protecting lives during a full-scale war,” he added, saying that military aid had been cut once before in January for a brief period.

Zelenskyy also said Ukraine is ready to sign a lucrative deal on rare-earth minerals and security with Washington. Trump was weighing whether to agree to the signing Tuesday, when he is scheduled to address a joint session of Congress, after Zelenskyy’s sign of contrition, according to a U.S. official familiar with the matter who was not authorized to speak publicly about it.

In an apparent reference to Trump’s criticism following the contentious White House meeting on Friday that Zelenskyy does not want a peace deal, the Ukrainian leader said, “None of us want an endless war.”

“Ukraine is ready to come to the negotiating table as soon as possible to bring lasting peace closer. Nobody wants peace more than the Ukrainians. My team and I stand ready to work under President Trump’s strong leadership to get a peace that lasts,” he said.

Asked by reporters in Moscow about Zelenskyy voicing readiness for the resumption of talks, Kremlin spokesman Dmitry Peskov said, “It’s good, it’s positive.”

In his post, Zelenskyy said the Oval Office meeting “did not go the way it was supposed to be.”

“It is regrettable that it happened this way. It is time to make things right,” he added. “We would like future cooperation and communication to be constructive.”

The pause of U.S. military aid catapulted Ukraine into alarm and apprehension. Zelenskyy’s statement came before Trump was expected to address the U.S. Congress later Tuesday.

“Regarding the agreement on minerals and security, Ukraine is ready to sign it in any time and in any convenient format,” Zelenskyy said. “We see this agreement as a step toward greater security and solid security guarantees, and I truly hope it will work effectively.”

French President Emmanuel Macron spoke by phone successively with Trump and Zelenskyy, Macron’s office said, and “welcomes” the Ukrainian’s “willingness to re-engage in dialogue with the U.S.” It released no details about the discussion with Trump.

U.K. Prime Minister Keir Starmer also spoke to the Ukrainian leader and “welcomed President Zelenskyy’s steadfast commitment to securing peace.”

Zelenskyy’s post came as officials in Kyiv said they were grateful for vital U.S. help in the war and want to keep working with Washington. Ukraine’s prime minister, though, said the country still wants security guarantees to be part of any peace deal and won’t recognize Russian occupation of any Ukrainian land. Those are potential stumbling blocks for Washington and Moscow, respectively.

Ukraine and its allies are concerned Trump is pushing for a quick ceasefire that will favor Russia, which Kyiv says cannot be trusted to honor truces.

A White House official said the U.S. was “pausing and reviewing” its aid to “ensure that it is contributing to a solution.” The order will remain in effect until Trump determines that Ukraine has demonstrated a commitment to peace negotiations, said the official, who spoke on condition of anonymity to discuss the assistance.

The pause in U.S. aid isn’t expected to have an immediate impact on the battlefield. Ukrainian forces have slowed Russian advances along the 1,000-kilometer (600-mile) front line, especially in the fiercely contested Donetsk region in the east. The Russian onslaught has been costly in troops and armor but hasn’t brought a strategically significant breakthrough for the Kremlin.
