US special envoy Steve Witkoff said on Friday that "constructive discussions" in Miami had tackled "potential avenues to de-escalate and conclude the war with Russia ahead of winter and advance efforts toward a durable and lasting peace".
In a statement posted to X, Witkoff said the meeting included "the E3, the European Commission, Ukraine and NATO". The agenda covered energy resilience, grain exports, security guarantees and "longer-term arrangements for Ukraine's and Europe's security to prevent future conflict", as well as Ukraine's post-war reconstruction and EU accession.
The meeting came hours after Putin told Trump that resuming talks with Ukraine is unlikely, citing drone attacks on Moscow during parliamentary elections last month.
US Secretary of State Marco Rubio had warned on Thursday that the conflict has reached a dangerous "stalemate", and that the failure to reach a negotiated settlement raised the risk of further escalation. "The other way that stalemates end is through escalation," he told reporters, warning that the conflict could spread to neighbouring NATO countries.
The renewed diplomacy follows a series of deadly Russian attacks, including a strike on civilian buses in eastern Ukraine that killed 33 people, which authorities called the deadliest single attack this year.
The talks were also overshadowed by the US-Russia diesel deal announced on Friday, with Trump blaming Ukrainian attacks on Russian refineries for surging fuel prices in the US. The deal drew criticism from US lawmakers, Ukrainian President Volodymyr Zelenskyy and European allies. Zelenskyy called the agreement a "gift to Putin". Hours after the deal was announced, a Ukrainian drone hit a Russian fuel site.
The Miami meeting follows visits to Moscow and Kyiv last month by Witkoff and Jared Kushner, as Washington seeks to revive negotiations that have so far yielded little progress.
