Witkoff said on social media that talks with officials from Ukraine and Europe focused on a "shared strategic approach."

Talks held between U.S., European and Ukrainian officials over the last three days in Florida aimed at ending Russia`s war in Ukraine focused on aligning positions, U.S. special envoy Steve Witkoff said on Sunday, calling those meetings and separate talks with Russian negotiators productive.

U.S. President Donald Trump has been pressuring Ukraine and Russia to come to an agreement on ending the nearly four-year-old conflict as soon as possible, but Russia wants to keep the Ukrainian areas it has seized and Kyiv has refused to cede ground.

After meeting Russian President Vladimir Putin`s special envoy Kirill Dmitriev on Saturday, Witkoff and Trump adviser Jared Kushner met on Sunday with officials from Ukraine and Europe, and then separately with the Ukrainian delegation, led by senior official Rustem Umerov.

Witkoff, in a social media post, called Sunday`s talks "productive and constructive" and focused on a "shared strategic approach between Ukraine, the United States and Europe."

In a separate X post that used some of the same language, Witkoff said his talks with Dmitriev were also "productive and constructive."

"Russia remains fully committed to achieving peace in Ukraine," Witkoff said in the post. "Russia highly values the efforts and support of the United States to resolve the Ukrainian conflict and re-establish global security."

Kremlin foreign policy aide Yuri Ushakov said earlier on Sunday that Ukrainian and European input into the peace proposals under discussion had not improved the prospects for peace, but said Dmitriev was scheduled to return to Moscow on Monday and would report to Putin on the outcome of his talks.

"After that, we will formulate the position with which we will proceed, including in our contacts with the Americans," Ushakov said in remarks posted by Kremlin pool journalist Pavel Zarubin on his Telegram channel.

The meetings in Miami were the latest in a series of talks between the U.S., Russia and Ukraine on a U.S.-drafted 20-point plan to end the war.

Witkoff said the U.S.-Ukraine meeting focused on four key points: further development of the 20-point plan, a multilateral security guarantee framework, a U.S. security guarantee framework for Ukraine, and further development on economics and prosperity to rebuild Ukraine.

Negotiators focused especially on "timelines" and "sequencing of next steps," Witkoff said.

U.S., Ukrainian and European officials earlier this week reported progress on security guarantees for Kyiv as part of the talks to end the war, but it remains unclear if those terms will be acceptable to Moscow.

"Peace must be not only a cessation of hostilities, but also a dignified foundation for a stable future," Witkoff said.

In response to a Reuters report on Friday, Director of National Intelligence Tulsi Gabbard said on X that U.S. intelligence assessments have shown Russia "does not currently have the capability to conquer and occupy all of Ukraine, let alone Europe."

Senator Lindsey Graham, a South Carolina Republican and close ally of Trump`s, said on NBC`s "Meet The Press" on Sunday it was still unclear if Putin would accept the current deal.

If he does not, Graham said, the Trump administration should adopt an approach similar to its recent actions with oil tankers near Venezuela and "seize ships that are carrying sanctioned Russian oil."

A Russian refusal to accept the current proposal should also lead to labeling "Russia a state sponsor of terrorism for kidnapping 20,000 Ukrainian kids," Graham said.
