Ukrainian President Volodymyr Zelensky says Ukraine's partners in Europe have failed to provide solid assurances that they will defend Ukraine in the case of a new Russian aggression.
"I am asking this very question to every one of our allies and thus far, the answer remains elusive a definitive and straightforward response yet," he told reporters on midweek.
These remarks follow a day after the UK and France signed a declaration of intent on deploying troops in Ukraine if a peace deal to end the war with Russia is agreed.
However, full security guarantees have yet to be solidified. The US, which has been leading efforts to halt the offensive, was reported to have abstained from signing such a pledge at discussions held in the French capital on Tuesday.
After the Paris talks, which involved some three dozen nations that form the group termed the 'Coalition of the Willing', UK Prime Minister Sir Keir Starmer said the two nations would "establish military hubs across Ukraine" to prevent any future incursion, while France's President Macron subsequently indicated a significant number of soldiers may be deployed.
Partner nations suggested that the US would take the lead in monitoring a truce. But the key issue of ceding land that Ukraine is being asked to grant to Russia as a component of the settlement terms are continuing to be negotiated.
Moscow has not yet commented on the announcement made in the French capital.
President Putin launched a comprehensive military assault of Ukraine in February 2022, and Russian forces now occupies about one-fifth of Ukrainian territory.
The UK Prime Minister characterized the bilateral declaration as "an essential component of our dedication to stand with Ukraine for the long-term".
He continued: "It paves the way for the legal framework under which allied military personnel could operate on Ukraine's territory, protecting Ukrainian airspace and waters, and regenerating Ukraine's military for the years to come."
The Ukrainian leader praised that accord as a "huge step forward".
A day later, however, he seemed more cautious.
"I perceive the determination, the political will, and that the allies are prepared, and the partners are ready to give us robust economic measures, strong security guarantees," he said when questioned if nations in Europe would come to Ukraine's aid.
"But as long as we lack such binding security pacts - formally ratified, supported by parliaments, backed by the U.S. Congress - this question cannot be answered. And even if they do, you must ultimately depend primarily on your inherent capabilities."
Negotiations in Paris were also notable due to the presence of US President Donald Trump's peace envoys, Jared Kushner and Steve Witkoff.
Witkoff said the participating countries "largely finished" their work on agreeing security protocols.
Last week, the President indicated a peace deal was "90% ready".
Questions of land and security guarantees have been at the forefront of unresolved issues for diplomats.
The Russian leader has consistently stated that Ukrainian troops must withdraw from all of Ukraine's eastern Donbas or Moscow will take control, dismissing potential concessions over how to end the war.
The Ukrainian President has thus far rejected relinquishing any land, but has suggested that Ukraine could redeploy its forces to an established line - but only if Russia did the same.
Moscow currently controls about three-quarters of the Donetsk oblast, and some nearly all of the adjacent Luhansk region. The pair of oblasts constitute the industrial Donbas region.
Attacks have been escalating against Ukrainian cities - particularly targeting power facilities. Moscow is also achieving slow progress in capturing more Ukrainian territory.
Ukraine has hit back at Russian targets with unmanned aerial vehicles, though with more limited success.
