HALLANDALE BEACH, Fla. (AP) — On Sunday, U.S. and Ukrainian officials engaged in approximately four hours of discussions, aiming to resolve the ongoing conflict between Russia and Ukraine. These talks come just days before a U.S. representative is set to visit Moscow to meet with Russian President Vladimir Putin.

After the meeting in Florida, Secretary of State Marco Rubio described the discussions with the Ukrainian delegation as productive, though he emphasized that more work is needed to secure a peace agreement.

“It’s not only about establishing terms to stop the fighting,” Rubio stated. “It’s also about creating conditions for Ukraine’s long-term prosperity. Today, we made progress on that front, but our work is far from complete.”

Steve Witkoff, President Donald Trump’s special envoy, is slated to have discussions with Putin in Moscow within the coming days.

Representing the U.S. in these crucial talks were Rubio, Witkoff, and Jared Kushner, Trump’s son-in-law. This diplomatic effort occurs at a critical moment, as Ukraine continues to resist Russian forces that invaded in 2022, while also grappling with a domestic corruption scandal.

Diplomats have focused on revisions to a proposed U.S.-authored plan that was developed in negotiations between Washington and Moscow. That plan has been criticized as being too weighted toward Russian demands. As the meeting began Sunday, Rubio focused on reassuring Ukraine.

“The end goal is, obviously, not just the end of the war,” Rubio said. “But it’s also about securing an end to the war that leaves Ukraine sovereign and independent and with an opportunity at real prosperity.”

“This is not just about peace deals,” the top American diplomat said as the teams sat down at the Shell Bay Club, a golf and racket club developed by Witkoff in Hallandale Beach.

Rustem Umerov, head of Ukraine’s security council, responded to Rubio by expressing his country’s appreciation for U.S. efforts, a message geared toward Trump, who has at times claimed that Ukraine has not been sufficiently grateful for U.S. assistance during the war.

“U.S. is hearing us,” Umerov said. “U.S. is supporting us. U.S. is working beside us.”

Umerov, who appeared with Rubio to deliver a brief statement to reporters after the talks, underscored Ukraine’s gratitude for U.S. support during nearly four-year war. But he offered no hints about what, if any, progress was made during the talks.

“Our objective is a prosperous, strong Ukraine,” Umerov said. “We discussed all the important matters that are important for Ukraine, for Ukrainian people, and the U.S. was super supportive.”

Rubio said the talks were comprehensive and went beyond finding agreement on ending the fighting. Trump has repeatedly said that if Ukraine builds deeper commercial ties to the United States it can help deter Russian aggression in the future.

To that end, the U.S. and Ukraine earlier this year signed an agreement granting American access to Ukraine’s vast mineral resources.

Among measures included in Trump’s draft peace proposal is the creation of a Ukraine Development Fund to invest in fast-growing industries, including technology, data centers and artificial intelligence. The proposal also calls for Washington to cooperate with Kyiv to jointly rebuild, develop, modernize and operate Ukraine’s natural gas infrastructure, including pipelines and storage facilities. Russia has repeatedly bombarded Ukraine’s energy infrastructure during the war.

“We also want to help Ukraine be safe forever, so never again will they face another invasion. And equally importantly, we want them to enter an age of true prosperity,” Rubio said. “We want the Ukrainian people to emerge from this war not just to rebuild their country, but to build it back in a way that will be stronger and more prosperous than this ever been.”

Umerov has been involved in the talks. But until now, Ukraine’s head negotiator had been Andrii Yermak, the powerful chief of staff of Ukrainian President Volodymyr Zelenskyy. On Friday, Zelenskyy announced the resignation of Yermak, after his home was searched by anti-corruption investigators.

Zelenskyy’s government has been roiled by fallout from a scandal over $100 million embezzled from the energy sector through kickbacks paid by contractors, causing newfound domestic pressures for Zelenskyy.

It was only a week ago that Rubio had met with Yermak in Geneva, with each side saying the talks had been positive in putting together a revised peace plan.

Among the other members of the Ukrainian delegation were Andrii Hnatov, the head of Ukraine’s armed forces, and presidential adviser Oleksandr Bevz.

The plan, which Trump has since played down as a “concept” or a “map” to be “fine-tuned,” would have imposed limits on the size of Ukraine’s military, blocked the country from joining NATO and required Ukraine to hold elections in 100 days. Negotiators have indicated the framework has changed, but it’s not clear how its provisions have been altered.

It had initially envisioned Ukraine ceding the entire eastern region of the Donbas to Russia — a sticking point for Kyiv.

Trump said on Tuesday that he would send Witkoff and perhaps Kushner to Moscow this week to meet with Putin about the plan. Kremlin spokesman Dmitry Peskov, in comments published Sunday on Russian state television, said Putin would see Witkoff before Thursday, when Putin departs for India.

Both Witkoff and Kushner, like Trump, hail from the world of real estate that values dealmaking over the conventions of diplomacy. The pair also were behind a 20-point proposal that led to a ceasefire in Gaza.

Zelenskyy wrote on X that the Ukrainian delegation would “swiftly and substantively work out the steps needed to end the war.”

In his nightly address on Saturday, Zelenskyy said the American side was “demonstrating a constructive approach.”

“In the coming days it is feasible to flesh out the steps to determine how to bring the war to a dignified end,” he said.

Attacks continue despite diplomatic efforts to end the war

On Saturday, Russian drone and missile attacks in and around Ukraine’s capital, Kyiv, killed at least three people and wounded dozens more, officials said. Fresh attacks overnight into Sunday killed one person and wounded 19 others, including four children, local officials said, when a drone hit a nine-story apartment block in the city of Vyshhorod in the Kyiv region.

In a post on Telegram Sunday, Zelenskyy said Russia had attacked Ukraine with 122 strike drones and ballistic missiles.

“Such attacks occur daily. This week alone, Russians have used nearly 1,400 strike drones, 1,100 guided aerial bombs and 66 missiles against our people. That is why we must strengthen Ukraine’s resilience every day. Missiles and air defense systems are necessary, and we must also actively work with our partners for peace,” Zelenskyy said.

“We need real, reliable solutions that will help end the war,” he added.

After Ukraine claimed responsibility for damaging a major oil terminal on Saturday near the Russian port of Novorossiysk, owned by the Caspian Pipeline Consortium, Kazakhstan told Ukraine on Sunday to stop attacking the Black Sea terminal. The CPC pipeline, which starts in Kazakhstan and ends at the Novorossisyk terminal, handles a large proportion of Kazakhstan’s oil exports.

“We view what has occurred as an action harming the bilateral relations of the Republic of Kazakhstan and Ukraine, and we expect the Ukrainian side to take effective measures to prevent similar incidents in the future,” Kazakhstan’s Foreign Ministry said in a statement.
