WASHINGTON (AP) — President Donald Trump is redoubling his efforts to end the war in Ukraine, announcing a second meeting with Russia’s Vladimir Putin one day before sitting down with Ukraine’s Volodymyr Zelenskyy at the White House.

Trump’s announcement came shortly after finishing a call with Putin on Thursday. A date has not been set, but Trump said the meeting would take place in Budapest, Hungary.

“I believe great progress was made with today’s telephone conversation,” Trump wrote on social media. The two leaders previously met in Alaska in August, which did not produce a diplomatic breakthrough, a source of frustration for the U.S. leader who had expected that his longstanding relationship with Putin could pave the way to resolving a conflict that began nearly four years ago.

Yuri Ushakov, Putin’s foreign affairs adviser, said the Russian president initiated the call, which he described as “very frank and trusting.” He said Putin emphasized to Trump that selling long-range Tomahawk missiles to Ukraine, something the U.S. president has publicly discussed, would “inflict significant damage to the relations between our countries.”

Trump was already scheduled to meet today with Zelenskyy, who has been seeking weapons that would allow Ukrainian forces to strike deeper into Russian territory. Zelenskyy has argued such strikes would help compel Putin to take Trump’s calls for direct negotiations to end the war more seriously.

Trump’s renewed focus on the war in Ukraine comes after forging a ceasefire that could end the war between Israel and Hamas in Gaza, a diplomatic accomplishment that he celebrated with a whirlwind trip to Israel and Egypt on Monday.

Ending the wars in Ukraine and Gaza was central to Trump’s campaign pitch last year, when he persistently pilloried President Joe Biden for his handling of the conflicts.

Although there has been fragile progress in Gaza, Trump has been stymied by Putin, unable to persuade the Russian leader to hold direct talks with Zelenskyy.

Earlier this week in Jerusalem, in a speech to the Knesset, Trump predicted the truce in Gaza would lay the groundwork for the U.S. to help Israel and many of its Middle East neighbors normalize relations. Trump also made clear his top foreign policy priority now is ending the largest armed conflict in Europe since World War II.

“First we have to get Russia done,” Trump said, turning to his special envoy Steve Witkoff, who has also served as his administration’s chief interlocutor with Putin. “We gotta get that one done. If you don’t mind, Steve, let’s focus on Russia first. All right?”

Today’s meeting with Trump and Zelenskyy will be their fourth face-to-face encounter this year. After their initial Oval Office conversation devolved into recriminations, they’ve forged a more amicable relationship.

Trump has said he’s considering selling long-range Tomahawk missiles to Kyiv, something Putin has said could further damage relations between Moscow and Washington.

Although such a sale would be a splashy move, it could take years to provide the equipment and training necessary for Ukraine to use Tomahawks, said Mark Montgomery, an analyst at the conservative Foundation for Defense of Democracies in Washington.
