Ukrainian President Volodymyr Zelenskyy said on Sunday that a U.S. document laying out security guarantees for Ukraine is “100 percent ready,” and is only waiting for a time and a place to be signed.

“For us, security guarantees are first and foremost guarantees of security from the United States. The document is 100 percent ready, and we are waiting for our partners to confirm the date and place when we will sign it,” Zelenskyy said at a news conference during a visit to Vilnius, Lithuania.

After it’s signed, Zelenskyy said, it would be “sent for ratification to the U.S. Congress and the Ukrainian parliament.”

He didn’t provide details on the nature of the guarantees provided in the document.

Zelenskyy’s remarks suggest that progress is being made after trilateral talks were held between Ukraine and Russia with U.S. mediation, the first meeting of its kind since the war began.

The meeting was held in Abu Dhabi, United Arab Emirates. In a statement, the UAE Ministry of Foreign Affairs said that it was hosting the two-day talks “as part of ongoing efforts to promote dialogue and identify political solutions to the crisis.”

While the meeting being held at all marked a sign of progress in the United States’ efforts to end the four-year conflict, no deal emerged from the talks.

However, both sides said they were open to continuing discussions, and another meeting in Abu Dhabi is scheduled for Feb. 1.

Speaking about the trilateral talks in Vilnius, Zelenskyy said that “the 20-point [U.S.] plan and problematic issues are being discussed. There were many problematic issues, but now there are fewer.”

One of those issues, for both sides, involves the status of Ukraine’s eastern provinces.

Russia has demanded Kyiv surrender its entire eastern industrial area of Donbas. Kremlin spokesman Dmitry Peskov said on Friday that Russia’s insistence on gaining all of Donbas was “a very important condition.”

While Russia has effective control over much of the disputed territory, Ukraine still holds around 20 percent of the Donetsk region of the Donbas—and has resisted Russia’s demands that it cede the territory as part of a peace agreement.

In Vilnius, Zelenskyy indicated that Ukraine hadn’t moved from the position that Ukraine’s territorial integrity should be upheld.

He said Moscow wants to do everything possible to get Ukraine to abandon these eastern regions which Russia has been unable to capture.

“These are two fundamentally different positions—Ukraine’s and Russia’s. The Americans are trying to find a compromise,” Zelenskyy said, adding that all sides must be ready to compromise, including the United States.

U.S. President Donald Trump, whose commitment to ending the conflict was a key pillar of his 2024 presidential campaign, has said that he believes an ultimate end to the conflict is “reasonably close.”

Ahead of the trilateral meeting in Abu Dhabi, Trump dispatched U.S. special envoy Steve Witkoff, Trump’s son-in-law Jared Kushner, and Josh Gruenbaum—who was recently appointed by Trump as senior adviser for his Board of Peace—to meet with Russian President Vladimir Putin.
