But there was no sign that Trump’s words would be matched by a change in U.S. policy, such as a decision to impose the heavy new sanctions on Moscow sought by Ukrainian President Volodymyr Zelenskiy as he traveled to New York this week.

“Putin and Russia are in BIG Economic trouble, and this is the time for Ukraine to act,” Trump wrote on Truth Social, shortly after meeting Zelenskiy on the sidelines of the U.N. General Assembly in New York.

“After seeing the Economic trouble (the war) is causing Russia, I think Ukraine, with the support of the European Union, is in a position to fight and WIN all of Ukraine back in its original form,” he said.

That would ostensibly require Kyiv to expel Russian forces from 20% of its territory, including the Crimean peninsula Moscow has held since 2014, in what would be an extraordinary reversal.

Trump has previously suggested Kyiv should consider giving up territory in order to make peace, fueling Ukrainian fears of behind-the-scenes talks for a deal that would seek to recognise its occupied lands as legally Russian.

Europe’s foreign policy chief, Kaja Kallas, praised Trump’s statements, saying: “These have been very strong statements that we haven’t heard before in such formats, so it is really good that we are in the same understanding now.”

Good, Constructive Meeting

The U.S. president’s tone was in stark contrast to his red-carpet treatment for Russian President Vladimir Putin at a summit in Alaska last month, part of an ostensible push to expedite an end to Russia’s war in Ukraine.

Zelenskiy told reporters at a briefing that he had a “good, constructive” meeting with Trump, declining to go into detail, while praising Trump’s statement on Truth Social as a “big shift.”

Since taking office in January, Trump has upended U.S. foreign policy, slashing foreign aid, imposing tariffs on friend and foe alike and cultivating warmer – if volatile – relations with Russia.

At the same time he has sought, so far with only limited success, to solve some of the world’s most intractable conflicts.

Some 150 heads of state or government are expected to address the chamber this week, including Trump, who is the second scheduled speaker after the session opens at 9 a.m. EDT (1300 GMT).

Trump will speak eight months into a second term marked by severe aid cuts that have sparked humanitarian worries and have raised doubts about the U.N.’s future, prompting U.N. Secretary-General Antonio Guterres to try to trim costs and improve efficiency.

White House officials have yet to provide guidance on what Trump will say.

But according to planning documents reviewed by Reuters, the Trump administration plans to call this week for sharply narrowing the right to asylum, seeking to undo the post-World War Two framework around humanitarian protection.

Trump’s more restrictive stance would include requiring asylum-seekers to claim protection in the first country they enter, not a nation of their choosing, a State Department spokesperson said.

Guterres and Trump are expected to meet formally for the first time since Trump returned to office in January.

Trump describes the U.N. as having “great potential” but says it has to get its “act together.” He has maintained the same wary stance on multilateralism that was a hallmark of his first term from 2017 to 2021 and also accused the world body of failing to help him try to broker peace in various conflicts.

Calls For a Palestinian State

The General Assembly takes place as the war between Israel and Hamas approaches its second anniversary on October 7. Israeli Prime Minister Benjamin Netanyahu is due the address the General Assembly on Friday.

Dozens of world leaders gathered on Monday to embrace a Palestinian state, a landmark diplomatic shift that faces fierce resistance from Israel and its close ally the United States.

The most far-right government in Israel’s history has declared there will be no Palestinian state as it pushes on with its fight against militant group Hamas in Gaza following the October 7, 2023, attack on Israel that killed some 1,200 people.

Israel has drawn global condemnation over its military conduct in Gaza, where more than 65,000 Palestinians have been killed, according to local health authorities.

Ukrainian President Volodymyr Zelenskiy and Russian Foreign Minister Sergei Lavrov will also address the General Assembly.
