President Zelensky has stated that European allies have failed to provide solid assurances that they will defend Ukraine in the event of a new Russian aggression.
"I continue to pose this critical question to every one of our allies and I have not received a clear, unambiguous answer yet," he stated to the press on midweek.
His comments come a day after Britain and France signed a statement of purpose on stationing forces in Ukraine if a peace deal to conclude the conflict with Moscow is agreed.
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 commitment at talks in Paris on the previous day.
After the Paris talks, which involved some 30 countries that form the group termed the 'Coalition of the Willing', British PM Keir Starmer said the UK and France would "set up operational bases across Ukraine" to deter future invasion, while France's President Macron later said thousands of troops may be sent.
Allies proposed that the US would assume a leading role in monitoring a truce. But the central sticking point of territorial concessions that Ukraine is being pressured to offer to Russia as part of the peace proposals are continuing to be negotiated.
The Russian government has not yet commented on the declaration made in the French capital.
President Putin initiated a full-scale invasion of Ukraine in February 2022, and Russian forces now occupies about one-fifth of Ukraine's land.
The UK Prime Minister characterized the bilateral declaration as "an essential component of our dedication to stand with Ukraine for the foreseeable future".
He continued: "It establishes the pathway for the juridical structure under which allied military personnel could function on Ukrainian soil, protecting Ukrainian airspace and waters, and regenerating Ukraine's military for the future."
The Ukrainian leader praised that accord as a "significant leap of progress".
A day later, however, he appeared less optimistic.
"I see the will, the political resolve, and that the partners are ready, and the allies are willing to give us strong sanctions, strong security guarantees," he said when questioned if nations in Europe would defend Ukraine.
"However, until we lack such binding security pacts - legally binding, endorsed by legislatures, backed by the U.S. Congress - this question cannot be answered. And even if they do, you still have to rely primarily on your own strength."
The Paris talks were also notable owing to the attendance of envoys from former President Trump's administration, Jared Kushner and Steve Witkoff.
One envoy stated the participating countries "mostly completed" their work on agreeing security protocols.
Recently, the President indicated a peace deal was "ninety percent complete".
Questions of land and security guarantees have been at the center of unresolved issues for diplomats.
The Russian leader has consistently stated that Ukraine's military must withdraw from all of Ukraine's eastern Donbas or Moscow will take control, rejecting any compromise over how to end the war.
Zelensky has so far ruled out relinquishing any land, but has suggested that Ukraine could redeploy its forces to an agreed point - but only if Russia did the same.
Russian forces now holds about three-quarters of the Donetsk oblast, and some 99% of the adjacent Luhansk region. The two regions form the Donbas industrial heartland.
It has been intensifying attacks against Ukrainian cities - particularly targeting power facilities. Russia has also made slow progress in seizing additional Ukrainian land.
Ukraine has hit back at Russian targets with drones, though with varying degrees of effectiveness.
