After a meeting between Putin and US President Donald Trump's envoy Steve Witkoff on Wednesday, Yuri Ushakov told reporters the Russian leader had agreed "in principle" to resume trilateral talks after November 10.
No such talks have taken place since February.
Ushakov, the Russian President's foreign affairs adviser, said the negotiations should focus on security guarantees for Russia and Ukraine after the conflict ends.
Witkoff travelled to St Petersburg to discuss Moscow's full-scale invasion of Ukraine, as US President Donald Trump pushes Kyiv to make a deal that stops the fighting.
Witkoff said in televised remarks at the start of the meeting that he hoped to discuss the resumption of the trilateral talks, which would allow technical teams to discuss the next steps towards a peace settlement.
Putin thanked Trump and Witkoff for their efforts to end the war.
The visit came a day after Witkoff met Ukrainian President Volodymyr Zelenskiy and other European leaders in the Norwegian capital, Oslo.
Witkoff's meetings suggested leaders are keen to bring new momentum to US-led peace efforts, more than four-and-a-half years after Russia's army invaded.
The meeting coincided with Russia releasing retired American teacher Stephen Hubbard, who had been jailed on charges of fighting as a mercenary in Ukraine.
Efforts by the Trump administration since early 2025 to end the war have made no significant progress, and Russia and Ukraine are still far apart in their terms for a settlement, as their armies remain locked on the battlefield and they pummel each other with daily long-range strikes.
Trump said on October 11 that Russia and Ukraine had agreed to a ceasefire in attacks on energy infrastructure but Russia has kept hammering Ukraine's power grid and Kyiv has hit Russian oil refineries.
However, Finnish President Alexander Stubb said late on Tuesday that the Oslo meeting, which he attended, "made genuine progress".
Witkoff described Tuesday's talks in Oslo as "productive", adding that "there is some degree of momentum".
He thanked Putin for lifting Russia's ban on diesel exports, which angered some US lawmakers, adding that it would help reduce prices for US farmers and truckers.
Moscow said the first diesel tanker to the US would be dispatched on Thursday, carrying 40,000 tonnes of fuel, with more to follow.
Putin said he was ready to discuss prospects for the restoration of US-Russian economic ties, including his country exporting large quantities of fertilisers to the US market, where farmers have been feeling the brunt of the trade friction with Canada.
He added he was also prepared to discuss the US-led conflict with Iran and use Moscow's relationship with Tehran to bring peace.
Witkoff planned to return to Oslo for more consultations after his trip to Russia, Norwegian Prime Minister Jonas Gahr Store said.
"I think we may have entered a phase now where the Russians are also looking for opportunities for diplomacy," Store told Norwegian broadcaster NRK.
After the Witkoff meeting, the Kremlin also said China was working to prepare a possible three-way summit with Putin, Trump and Chinese leader Xi Jinping in November during the APEC summit in China.
At the White House on Tuesday, Trump increased the pressure on Zelenskiy to come to an agreement with Russia as relations between the two men have soured again.
"We want Zelenskiy to make a deal," Trump told reporters in the Oval Office.
"We've given a lot to Ukraine. We've gotten absolutely nothing back except grief, death, tremendous monetary loss."
Amid fears that Washington was turning its back on Ukraine, Zelenskiy said Kyiv was once again receiving early warnings from its partners about incoming Russian missiles, after recent strikes that he said occurred without enough notice from allies.
The change happened after Zelenskiy spoke with his American counterparts, including a phone call with US Secretary of State Marco Rubio.
