US negotiators have floated the idea of Ukraine's withdrawal from its eastern region of Donbas in exchange for joining NATO, President Volodymyr Zelenskiy says, following the latest round of peace talks with Russia in Abu Dhabi.
This is the first time the question of linking NATO membership to territorial concessions has been raised during the talks, Zelenskiy said in remarks to reporters released by his office on Saturday.
"The Americans raised a question: 'What if Ukraine joins NATO? Would Ukraine withdraw from Donbas?" he said.
"That is why I believe NATO is back on the agenda. But you have also heard (Russian President Vladimir) Putin's signals, and this is an extremely difficult conversation."
Putin has long said Ukrainian membership of NATO is a red line for Moscow, citing the issue as one reason for launching Russia's full-blown invasion in 2022.
Zelenskiy said Kyiv was not ready to concede territory but said that if it received a comprehensive package including security guarantees, the right to a strong and well-funded Ukrainian army and funds to rebuild, he would put the question to a national referendum.
Echoing comments made by European leaders at a summit in Dublin on Friday, Zelenskiy dismissed Russia's call for a broad agreement on European security architecture to be reached before the specifics are agreed on how to end the war in Ukraine.
"We cannot turn everything upside down and start by talking about changing the security framework in the world or across the continent overall, and only then talk about ending this war. This war must be ended first," he said.
US President Donald Trump's envoy Jared Kushner said the two sides had set out "maximalist positions" in the talks but in private discussions both "understand that practical compromises will be necessary to end this war".
"Serious and constructive work continues among those of us committed to finding solutions," Kushner said in a social media post.
Zelenskiy also dismissed Putin's suggestion for a local humanitarian ceasefire in Kostiantynivka, a hotly contested city in Ukraine's eastern Donetsk region, saying it reflected Moscow's inability to take the city by force. Civilians there have already had the opportunity to evacuate, he added.
"Putin simply wants us to leave Kostiantynivka so that they can move in and occupy the entire city that way," he said.
Ukraine has given a list of seven or eight other frontline settlements where civilians, including children, are trapped for a potential humanitarian truce but Russia prefers to use them as military targets, Zelenskiy said.
The two days of US-brokered talks between Ukraine and Russia concluded on Wednesday in the Emirati capital without a major breakthrough, though the sides agreed to a prisoner exchange that will involve more than 1,000 people, Zelenskiy said.
