Ukrainian President Volodymyr Zelensky met in Oslo on 20 October with US special envoy Steve Witkoff, Norwegian Prime Minister Jonas Gahr Støre and Finnish President Alexander Stubb to discuss a peace proposal for ending Russia's war against Ukraine.

Zelensky offers to halt strikes on Russian oil refineries if Russia stops hitting Ukrainian energy
On 11 October, President Volodymyr Zelensky said Ukraine is ready to stop strikes on Russian oil refineries and other energy infrastructure if Russia reciprocally halts strikes on Ukrainian energy. The offer came the same day U.S. President Donald Trump announced that Ukraine and Russia had agreed to an immediate 'energy ceasefire.' Zelensky said the U.S. announcement was news to him and that the Armed Forces of Ukraine had received the relevant orders. The same day, Russia struck the TEC-5 thermal power plant in Kharkiv, continuing a week in which Zelensky said Russian forces launched roughly 1,450 aerial bombs, 75 missiles and more than 1,640 strike drones at Ukraine.

Miami talks on Ukraine end after one day as Trump announces Russian diesel deal with Putin
On 9 October, US, Ukrainian, European and NATO representatives met in Miami to discuss ways to end Russia's war before winter, but the planned two-day meeting ended after a single day.

Trump announces Russia diesel deal after Putin call; Ukraine and European leaders condemn move
On 9 October 2026, US President Donald Trump announced he had spoken by phone with Russian President Vladimir Putin and agreed to lift US sanctions on Russian diesel, allowing large-scale exports to American and global markets. The US Treasury's Office of Foreign Assets Control issued General License No. 135 authorising the imports until 7 April 2027. Ukrainian President Volodymyr Zelensky sharply criticised the decision, calling it a "weak" and "unfair and dishonest" birthday gift to Putin that gives Russia additional billions for the war, while EU foreign policy chief Kaja Kallas, the UK, Germany, France, Finland, Sweden, Estonia, and US Democrats all condemned or distanced themselves from the deal. Talks between Ukrainian, US and European delegations in Miami ended early after the announcement, and a senior Ukrainian official told the Financial Times that long-range drone strikes on Russian refineries would continue.

Ukrainian delegation heads to Washington for two days of talks as Rubio says diplomatic end to war is currently "unattainable"
A Ukrainian delegation is to travel to the United States on 9–10 October for two days of talks with American officials, including US special envoys Steve Witkoff and Jared Kushner, with European partners also expected to join. The trip comes as US Secretary of State Marco Rubio told the Greek outlet Kathimerini that a diplomatic end to Russia's war against Ukraine is currently "unattainable," describing the conflict as a "strategic deadlock" driven by Russia's demand for full control over Donbas, which Kyiv rejects. President Volodymyr Zelensky, visiting the site of an October 7 Russian missile strike on a residential building in Pryluky, publicly rejected Rubio's framing and called for stronger sanctions and pressure on Russia rather than economic engagement with Moscow.

US envoys visit Kyiv for first time, signal return to trilateral talks but report no breakthrough
US special envoys Steve Witkoff and Jared Kushner travelled to Kyiv on 6 September 2026 for their first visit to Ukraine since Donald Trump's second presidential term began, after meeting Vladimir Putin in Moscow on 5 September. They held three rounds of talks with President Volodymyr Zelensky, joined in the second round by national security advisers from France, Germany and the United Kingdom, and announced a planned return to the US–Ukraine–Russia trilateral format and US support for a 'winter package' of assistance for Ukraine. Zelensky reported receiving a message that 'the Russians are ready to negotiate' but remained sceptical, while the Kremlin, Bloomberg sources and the Institute for the Study of War said the Moscow talks produced no substantive concessions.
