PARIS —  French President Emmanuel Macron welcomed Donald Trump to Paris on Saturday with a full a dose of presidential pomp and they held an impromptu meeting with Ukraine’s Volodymr Zelensky on a day that mixed pageantry with attention to pressing global problems.

Trump, the once and future American president, said when he arrived at the Elysee Palace for a face-to-face meeting with Macron — soon expanded to include Zelensky — that the two would be discussing a world that’s gone “a little crazy.”

Trump’s visit to France, part of a global a celebration of the reopening of Notre Dame Cathedral five years after a devastating fire, came as Macron and other European leaders are trying to win Trump’s favor and persuade him to maintain support for Ukraine in its defense against Russia’s invasion. Macron’s office said that would be discussed as well as the wars in the Middle East.

As Trump arrived at the official residence of the French president, Macron went out of his way to project an image of close ties, posing for multiple handshakes interspersed with plenty of back-patting. Trump said it was “a great honor” and talked about the “great relationship” they have had. A grand red carpet was rolled out in the same way the French welcome sitting American presidents.

Before they went inside, Trump said, “It certainly seems like the world is going a little crazy right now. And we’ll be talking about that.”

Zelensky arrived at the palace about 45 minutes after Trump. Macron had planned to meet with Zelensky, and the French president’s office said the three-way meeting was proposed by Macron and arranged shortly before Trump’s arrival. Trump has pledged to end the war in Ukraine swiftly but has not specified how, raising concerns in Kyiv about what terms may be laid out for any future negotiations.

Macron, who has had an up-and-down relationship with Trump, has made a point of cultivating a relationship since the Republican defeated Democratic Vice President Kamala Harris last month. But Macron’s office nonetheless played down the significance of the invitation, saying other politicians not now in office had been invited as well.

Trump was invited as president-elect of a “friendly nation,” Macron’s office said, adding, “This is in no way exceptional, we’ve done it before.”

The red carpet treatment, however, was a sign of how eager Macron and other European leaders are to win Trump’s favor and placate him even before he takes office.

Trump is known to revel in pomp and circumstance. One of his first trips as president his first term was to Paris, where Macron made him the the guest of honor at Bastille Day events. Trump later said he wanted to replicate the grand military parade back in the United States.

President Biden was invited as well but will not attend. White House Press Secretary Karine Jean-Pierre cited a scheduling conflict and said First Lady Jill Biden will represent the United States.

The meeting with the French president is taking place before the Notre Dame event, as will the get-together with Britain’s Prince William, who is also scheduled to meet with Jill Biden, according to the British royal palace.

In an effort to build trust with the incoming U.S. administration, top Zelensky aide Andriy Yermak met key members of Trump’s team on a two-day trip earlier this week. A senior Ukrainian official, who spoke on condition of anonymity because he was not authorized to speak publicly, described the meetings as productive, but declined to disclose details.

Relations between France and the U.S. during Trump’s first term began warmly enough but grew increasingly strained over time.

Macron was the guest of honor at Trump’s first state dinner, and Trump traveled to France several times. But the relationship suffered after Macron criticized Trump for questioning the need for NATO and raising doubts about America’s commitment to the mutual defense pact.

During the 2024 presidential campaign, Trump often mocked Macron, imitating his accent and threatening to impose steep tariffs on wine and Champagne bottles shipped to the U.S. if France tried to tax American companies.

But Macron was one of the first global leaders to congratulate Trump after last month’s election.

When he accepted the invitation to travel to Paris, Trump said Macron had done “a wonderful job ensuring that Notre Dame has been restored to its full level of glory, and even more so. It will be a very special day for all!” A fire in 2019 nearly destroyed the 861-year-old landmark.

More than 20 French government security agents were helping ensure Trump’s safety alongside the Secret Service, according to French national police. A special French police van provided anti-drone protection for Trump’s convoy.

Security was tighter than usual outside the U.S. Embassy and other sites around Paris for the Notre Dame reopening, where dozens of international VIPs were expected.

Trump was president in 2019 when the fire engulfed Notre Dame, collapsing its spire and threatening to destroy one of the world’s greatest architectural treasures.

“So horrible to watch the massive fire at Notre Dame Cathedral in Paris,” he wrote on what was then Twitter, offering his advice to the city. “Perhaps flying water tankers could be used to put it out. Must act quickly!” he wrote.

French officials appeared to respond shortly after, noting that “All means” were being used to extinguish the flames, “except for water-bombing aircrafts which, if used, could lead to the collapse of the entire structure of the cathedral.”

Last weekend, Trump announced that he intends to nominate real estate developer Charles Kushner, the father of his son-in-law, Jared Kushner, to serve as ambassador to France. The elder Kushner was pardoned by Trump in December 2020 after pleading guilty years earlier to tax evasion and making illegal campaign donations.
