Ukrainian President Volodymyr Zelenskiy said on Thursday that Kyiv and its allies have an understanding of a general framework for security guarantees and that documents were being prepared in each of the countries that have agreed to contribute.

Speaking at a briefing in Paris, he added that a strong Ukrainian army would be central to any such commitments and urged European defence firms to boost their work to full capacity.

Ukraine’s allies in the so-called ‘coalition of the willing’ are joining forces to strengthen Ukraine’s security guarantees through air, sea, land and the regeneration of Ukraine’s forces, European Council President Antonio Costa said on Thursday.

“At the same time, we continue our work to put pressure on Russia through further sanctions. Russia must stop the killing immediately,” Costa also said in a post on social media platform X after meeting with the coalition in Paris.

French President Emmanuel Macron said US support to Ukraine security guarantees will be finalised in the coming days. He was speaking after a call with US President Donald Trump in the aftermath of a meeting of countries supporting Ukraine.

“We held a call with President Trump (…) The conclusions of this call are simple: in the coming days, we will finalise US support and these security guarantees. The United States, as I said, has been involved in every stage of the process,” Macron told reporters.

Speaking after talks between leaders earlier in the day, Czech Prime Minister Petr Fiala said Ukraine’s allies agreed on the need to continue intensive aid to Kyiv for its defence and that lasting peace required robust security guarantees.

“It is necessary to continue with pressure on Russia with the aim of creating conditions for just and lasting peace,” Fiala said in Prague, following talks held both virtually as well as in Paris among countries in the “coalition of the willing.”
