Donald Trump and Vladimir Putin will meet face-to-face in Hungary to discuss ending Russia's full-scale invasion of Ukraine, the US president has said.
The summit will be their second since Mr Trump's return to the presidency.
A meeting in Alaska in August failed to yield a deal and was widely seen as a diplomatic win for the Russian president, who made no concessions and convinced Mr Trump to drop demands for a ceasefire.
Russia has intensified its aggression against Ukraine in the months since. It has targeted energy infrastructure with a relentless drone assault, cutting power across the country as winter approaches.
Mr Trump announced plans for the second meeting after a phone conversation with Mr Putin on Thursday, local time, which he called "very productive".
The White House said the call lasted more than two hours.
Mr Trump said the meeting would take place after talks between US Secretary of State Marco Rubio and high-level advisors from the US and Russia next week, at a location yet to be chosen.
"President Putin and I will then meet in an agreed upon location, Budapest, Hungary, to see if we can bring this 'inglorious' War, between Russia and Ukraine, to an end," Mr Trump posted on his social media platform, Truth Social.
Ukrainian president Volodymyr Zelenskyy is set to visit the White House for talks with Mr Trump on Friday.
The US has been considering supplying Ukraine with long-range Tomahawk missiles that could strike deep inside Russia.
Mr Putin told Mr Trump supplying Tomahawks would harm the peace process and damage US-Russia ties, Reuters reported, citing a Kremlin aide.
The aide, Yuri Ushakov, told reporters the Putin-Trump call took place at Russia's request.
Mr Trump's post made no mention of any meeting between the Russian and Ukrainian presidents, which had been slated as the next step in negotiations.
In August, Mr Trump said he was arranging a meeting between Mr Zelenskyy and Mr Putin, which was to have been followed by a trilateral meeting with him.
Mr Trump said at the time that Mr Putin had agreed to those meetings during a telephone call.
That call followed talks between Mr Trump, Mr Zelenskyy and a group of European leaders in Washington.
But there was widespread scepticism about Mr Putin's true commitment to that meeting, and the Kremlin's subsequent statements about it were less committal.
Mr Trump campaigned for the presidency with a promise of bringing a quick end to the war, which was sparked by Russia's full-scale invasion in February 2022.
The US president has threatened Russia with a range of economic penalties, including "secondary" sanctions on its trading partners.
In August, he doubled tariffs on Indian products to 50 per cent to pressure India to stop buying Russian oil.
On Wednesday, he said Indian Prime Minister Narendra Modi had assured him India would stop buying Russian oil. Mr Trump said he was now "going to get China to do the same thing".
India has not confirmed Mr Trump's claim, but a statement from its foreign ministry said the country had always sought oil from a range of suppliers.
