The call came amid concerns in Kyiv and European capitals that Trump may concede too much to the Russian president, reports AFP.
Vladimir Putin and Donald Trump held a critical phone call on Tuesday, speaking for at least an hour and a half about a Ukraine ceasefire plan that could require Kyiv to cede large areas of territory to Russia.
The US president has already made it clear that he wants to discuss which parts of occupied Ukraine Russia will be allowed to keep, saying over the weekend that Moscow and Washington are talking about "dividing up certain assets."
The call took place amid fears in Kyiv and European capitals that the 78-year-old Trump could give too much ground to the Russian leader, whom he has repeatedly praised.
Putin's spokesman, Dmitry Peskov, said that "the conversation has come to an end," according to the state-run TASS news agency. The White House confirmed the call had ended and said it would issue a statement soon.
The talks were lengthy, with Trump's deputy chief of staff, Dan Scavino, saying the call began at 1400 GMT and was "going well." About 90 minutes later, he said it was still ongoing.
A ceasefire remains far from guaranteed.
Kyiv has agreed to pause fighting for 30 days and enter negotiations with Russia more than three years into Moscow's invasion, but Putin has set several conditions, including barring Ukraine from joining NATO.
Trump said on his Truth Social network late Monday that "many elements of a final agreement have been agreed to, but much remains" to be settled.
Before the call, Putin delivered a hardline, anti-Western speech, claiming the West would continue trying to undermine Russia even if sanctions imposed over its invasion of Ukraine were lifted.
He mocked the G7 group of wealthy democracies— from which Russia was expelled in 2018— to loud applause, saying it was too small to "see on a map."
Kyiv said it expected Moscow to "unconditionally" accept the ceasefire.
"It is time for Russia to show whether it really wants peace," Ukraine’s Foreign Minister Andriy Sybiga said.
Ukrainian President Volodymyr Zelensky has warned that Putin does not seek peace but is trying to strengthen his military position ahead of any pause in fighting.
For over three years, Russia has launched near-daily drone and missile attacks on Ukraine, occupying about 20% of the country's south and east while pressing a slow but steady advance in recent months.
Putin has claimed a ceasefire would benefit only Kyiv and not the Russian army, which he said was "advancing."
Moscow has also ruled out accepting Western troops as peacekeepers in Ukraine and opposes US military aid to Kyiv during any halt in fighting.
Efforts toward a ceasefire gained momentum in February when Trump revealed last month that he had spoken to Putin— a surprise call that disrupted Western attempts to isolate the Russian leader amid his ongoing invasion.
Trump then upended years of US policy by engaging in a televised shouting match with Zelensky in the Oval Office on February 28, leading to a temporary suspension of billions of dollars in US military aid to Kyiv.
On Sunday, Trump said he would discuss "land" and "power plants" with Putin— a likely reference to the Russian-occupied Zaporizhzhia nuclear plant, Europe’s largest, which Moscow seized in the early days of the war.
Determined to fulfill his election promise to end the war in Ukraine, Trump has blamed his predecessor, Joe Biden, for fueling the conflict through his policies on Russia.
"It must end NOW," he wrote on Truth Social.
As Washington and Moscow prepared for the talks, authorities in Russia’s Kursk region evacuated several hundred civilians from areas retaken from Ukraine last summer.
The Kremlin has hailed Moscow’s swift offensive there last week as a major success, with Putin urging Ukrainian soldiers to surrender or be killed.
Russian pensioner Olga Shkuratova’s husband was killed last week in the fighting as Russia forced Ukrainian troops out of her village, Goncharovka.
"A shell hit. Everything was blown apart in a second. No house, no garage, no barn," the 62-year-old told AFP as volunteers helped evacuate her.
