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.
