MIAMI — A senior Kremlin envoy said Saturday that peace talks based on a US-proposed plan to end the nearly four-year war in Ukraine are moving forward “constructively,” as Washington intensifies diplomatic efforts to broker a deal between Moscow and Kyiv.

Kirill Dmitriev, a Russian presidential envoy, told reporters in Miami that discussions with U.S. officials had begun earlier and would continue through the weekend.

Dmitriev met with Steve Witkoff, a special envoy of Donald Trump, and Trump’s son-in-law Jared Kushner, according to Russia’s state news agency RIA Novosti.

The Florida talks follow meetings held earlier this week in Berlin between U.S., Ukrainian and European officials as part of Washington’s renewed push to end the conflict.

Volodymyr Zelenskyy said Saturday that Ukraine’s next steps would depend heavily on the U.S. position following its discussions with Russia. His comments came a day after Ukraine’s chief negotiator said Kyiv had concluded separate talks with American and European partners in the United States.

Trump has made ending the war in Ukraine a central foreign policy priority, launching an intensive diplomatic campaign since returning to office. However, negotiations remain stalled by sharply opposing demands from Moscow and Kyiv.

Vladimir Putin has recently reinforced Russia’s hard-line stance, signaling that the Kremlin will press ahead with its military objectives if Ukraine does not accept Moscow’s conditions in peace talks.

On Friday, Putin said Russia was confident it would achieve its goals through military means if negotiations failed, as Russian forces continue to make incremental gains on the battlefield despite heavy losses.

Meanwhile, European Union leaders agreed Friday to provide €90 billion ($106 billion) in military and economic support to Ukraine over the next two years.

The funds will be raised through borrowing, after EU members failed to agree on using frozen Russian assets due to objections from Belgium. — Agencies
