The United States and Ukraine are reportedly set for "intensive work" on the proposed 28-point peace plan with Russia on Monday (November 24).

The two sides were reportedly working on an "updated and refined peace framework" during meetings in Geneva, officials from both countries confirmed in a joint statement obtained by NBC News, which acknowledged "meaningful progress" from the "highly productive" discussions, though no specific details were released. European allies have expressed optimism, but also warned of "major issues" remaining ahead of President Donald Trump's deadline to reach a deal by Thursday (November 27).

Russia claimed that it had been shut out of the discussions on Monday and it's unclear whether it would accept any counterproposals. Trump also gave his take on the negotiation in a post shared on his Truth Social account early Monday morning.

"Is it really possible that big progress is being made in Peace Talks between Russia and Ukraine??? Don’t believe it until you see it, but something good just may be happening," he wrote.

Ukrainian President Volodymyr Zelenskyy confirmed that he discussed the proposal with leaders of France, the United Kingdom and Germany and that he "value the efforts of the United States, President Trump, and his team aimed at ending this war" via CBS News.

"Ukraine may find itself facing a very difficult choice: Either loss of dignity, or the risk of losing a key partner. Either a difficult 28 points, or an extremely difficult winter," Zelenskyy said in a separate video shared on social media Friday (November 21).

Zelenskyy also reportedly discussed the proposal with Vice President JD Vance on Friday, a Ukrainian official confirmed to CBS News.

The 28-point U.S. plan reportedly includes four general buckets: peace in Ukraine, security guarantees, security in Europe and future U.S. relations with both Russia and Ukraine, the sources confirmed, though it's unclear how it will approach more contentious issues such as territorial control in eastern Ukraine where the Kremlin has gained some control but far less than it's demanded previously, Axios had previously reported.

“The plan focuses on giving both sides security guarantees to secure a lasting peace,” the senior official said via NBC News. “It includes things Ukraine wants and needs to have a durable peace.”

The senior official wouldn't outline details of the proposed plan as negotiations on some key parts are ongoing. Trump's special envoy, Steve Witkoff, Vice President JD Vance, Secretary of State Marco Rubio and the president's son-in-law Jared Kushner were all reported to have had some involvement in drafting the plan, according to the official.

Witkoff was previously reported to have been working closely with Russian envoy Kirill Dmitriev on negotiations and was expected to meet with Ukrainian President Volodymyr Zelenskyy in Turkey on Wednesday (November 19), but his trip was postponed. Witkoff had, however, reportedly discussed the drafted plans with Zelenskyy's national security adviser, Rustem Umerov, during a meeting in Miami that took place earlier this week, a Ukrainian official confirmed to Axios.

"We know the Americans are working on something," the official said.
