US President Donald Trump has said that he and his Russian counterpart Vladimir Putin agreed to another summit to discuss ending the war in Ukraine, one day before Mr Trump is due to hold talks with Ukrainian leader Volodymyr Zelensky.
President Trump said he and Mr Putin would meet in the Hungarian capital Budapest soon after a more than two-hour-long phone call that he described as productive.
Moscow made no immediate comment.
The surprise development came as Mr Zelensky heads to the White House tomorrow to push for more military support, including potential long-range offensive missiles.
Yet the positive tone following the US-Russia call appeared to leave in question the possibility of such support in the near term.
President Zelensky said that momentum in the Middle East peace process would help end his country's conflict with Russia.
Writing on Telegram, he did not refer directly to Mr Trump's agreement to hold fresh talks with President Putin, but said it was clear that Russia was keen to resume dialogue "upon hearing of Tomahawks" - a reference to the US leader's suggestion that he might provide Ukraine with the missiles.
Ukraine and Russia have been escalating their war with massive attacks on energy infrastructure while NATO struggles to respond to a spate of Russian air incursions.
The Trump-Putin meeting will follow lower-level talks between Russia and the US next week, Mr Trump said.
No date was provided for the leaders' meeting.
In a post on Truth Social, Mr Trump said that he would brief President Zelensky on the Russia talks in the Oval Office tomorrow.
"I believe great progress was made with today's telephone conversation," he added.

Ukraine has been seeking US Tomahawk long-range missiles, which would put Moscow and other major Russian cities within range of missile fire.
President Trump, who has vowed to end the war that Russia started with its invasion of Ukraine in 2022, had before expressed increasing frustration with Mr Putin over ongoing attacks.
The US leader said that he could supply the long-range weapons to Ukraine if his Russian counterpart fails to come to the negotiating table.
In its latest barrage, Russia launched more than 300 drones and 37 missiles at infrastructure across Ukraine in overnight attacks, Mr Zelensky said.
Ukraine has ramped up its own attacks on Russian targets, including an oil refinery in the Saratov region.
Russia has been hitting Ukraine's energy and power facilities for consecutive winters as the war drags into its fourth year.
