The Crimean peninsula officially joined the Russian Federation after an overwhelmingly positive vote in 2014

Kiev will not discuss recognizing Crimea as Russian territory, Ukraine's Vladimir Zelensky told journalists on Tuesday, according to Ukrainian outlet Suspilne.

The US will propose officially accepting the peninsula as part of the Russian Federation at a meeting with Kiev and its European backers on Wednesday, as part of a broader peace deal to stop the conflict, the Washington Post wrote on Tuesday citing anonymous sources.

"[Crimea] is our territory, the territory of the people of Ukraine. We have nothing to talk about on this topic - it is outside our Constitution," Zelensky said.

The Ukrainian leader claimed that discussing the issue of sovereignty over Crimea could only lead to additional fighting.

"As soon as we start talking about Crimea, about our sovereign territories, we enter the format of prolonging the war," he said, adding that this is "what Russia wants."

Last week, Zelensky lashed out over the subject in a press conference, saying that US special envoy Steve Witkoff had no authority to discuss such issues with Russia.

The US proposal on Crimea was already presented to Ukraine in Paris last week, and includes eventual sanctions relief for Moscow in exchange for a peace deal, the Post reported on Tuesday, citing sources familiar with the deliberations.

Ukrainian officials interpreted the plan as Washington's final offer before the US washes its hands of peace efforts, the newspaper wrote, citing anonymous sources.

US President Donald Trump is expected to present Washington's "final offer" on a full ceasefire deal as early as next week, the New York Post wrote on Saturday, citing a senior administration official.

In 2014, the predominantly ethnically Russian population of Crimea voted to join Russia following a Western-backed armed coup in Kiev. Both Ukraine and its Western supporters continue to claim that the referendum was illegitimate.
