Ukrainian President Volodymyr Zelensky says European allies have not given him solid assurances that they will defend Ukraine in the case of a future Russian attack.
"I am asking this very question to all our partners and thus far, the answer remains elusive a definitive and straightforward response yet," he stated to the press on Wednesday.
These remarks follow a day after Britain and France signed a declaration of intent on stationing forces in Ukraine should a ceasefire agreement to end the war with Russia is reached.
However, comprehensive defense assurances have not been agreed. The US, which has been spearheading initiatives to end the invasion, was reported to have abstained from signing such a pledge at talks in Paris on the previous day.
Following the negotiations in Paris, which included some three dozen nations that comprise the so-called Coalition of the Willing, British PM Keir Starmer said the two nations would "set up operational bases across Ukraine" to deter future invasion, while France's President Macron subsequently indicated a significant number of soldiers may be deployed.
Partner nations suggested that the United States would take the lead in overseeing any ceasefire. But the central sticking point of ceding land that Ukraine is being asked to grant to Russia as part of the peace proposals are continuing to be negotiated.
The Russian government has thus far remained silent on the declaration made in the city of Paris.
President Putin launched a full-scale invasion of Ukraine in February 2022, and Russian forces currently controls about one-fifth of Ukrainian territory.
The UK Prime Minister characterized the bilateral declaration as "a vital part of our commitment to support Ukraine for the foreseeable future".
He added: "It paves the way for the legal framework under which allied military personnel could function on Ukrainian soil, securing Ukraine's skies and seas, and regenerating Ukraine's military for the years to come."
Zelensky hailed that agreement as a "significant leap of progress".
Twenty-four hours afterward, however, he seemed more cautious.
"I see the will, the political will, and that the allies are prepared, and the partners are ready to give us robust economic measures, powerful defense assurances," he said when questioned if nations in Europe would defend Ukraine.
"However, until we lack such security guarantees - legally binding, endorsed by legislatures, backed by the U.S. Congress - this question remains unresolved. And should they materialize, you still have to rely primarily on your own strength."
The Paris talks were also notable due to the presence of US President Donald Trump's peace envoys, Jared Kushner and Steve Witkoff.
One envoy stated the participating countries "mostly completed" their work on agreeing security protocols.
Recently, the President indicated a settlement was "90% ready".
Questions of land and defense pledges have been at the center 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, rejecting any compromise 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 region, and some 99% of the neighbouring Luhansk. The pair of oblasts form the Donbas industrial heartland.
Attacks have been escalating against cities in Ukraine - with a focus on power facilities. Russia has also made incremental advances in seizing additional Ukrainian land.
Ukraine has hit back at objectives inside Russia with unmanned aerial vehicles, though with more limited success.
