Ukrainian President Volodymyr Zelensky said Sunday that Ukraine stands ready to agree on security guarantees based on NATO Article 5 as a part of a compromise in the peace process, the Ukrinform news agency reported.

"From the very beginning, Ukraine's desire was to join NATO, these are real security guarantees. Some partners from the United States and Europe did not support this direction," he told reporters.

"Article 5-like guarantees from the United States and from European partners, as well as from other countries -- Canada, Japan ... would provide an opportunity to prevent another arrival of Russian troops," Zelensky said, adding, "It is already a compromise on our part."

Zelensky said he was not yet ready to disclose specific details of the proposed security guarantees, saying they would be known in a day or two.

Zelensky arrived in Berlin on Sunday afternoon for talks with German Chancellor Friedrich Merz and other European leaders.

German newspaper Bild reported that Zelensky may also hold talks with representatives of U.S. President Donald Trump, but did not elaborate further.
