Before the Paris conference, the organizers indicated that the protective structure had been damaged by a Russian drone in February 2025 and that the remaining approximately 500 million euros still needed to be raised, with the aim of completing the work by spring 2027. During the same period, the G7 countries had raised or pledged just over 260 million euros, or just over half of the estimated need.
The United States announced in April that it would unlock up to 100 million dollars for reconstruction and urged the other G7 countries to contribute, while France hosted the meeting as it holds the G7 presidency this year.
