Ukrainian President Volodymyr Zelensky said on Sunday that Ukraine stands ready to agree to security guarantees based on NATO's Article 5 as part of a compromise in the peace process, according to media reports.
"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," the Ukrinform news agency quoted Zelensky.
Zelensky said Article 5-like guarantees from the United States and from European partners, as well as from other countries, "would provide an opportunity to prevent another arrival of Russian troops." He also called it "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.
Ukrainian president 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.
According to Ukrinform, Zelensky said the same day that Ukraine must be prepared for any possible developments regarding elections.
"I asked our partners to assist with the security situation if elections are held, and I said that lawmakers should prepare options for how this could be implemented if the situation develops in that direction. They should work out, in the near future, options for holding elections," he said in a statement in response to journalists' questions.
He said he had received "signals" from the United States and President Trump regarding Ukraine's presidential election.
