In Paris, a conference co‑hosted by France, Ukraine and the European Bank for Reconstruction and Development brought together representatives of 15 donors who confirmed contributions totaling €278 million to restore the Chernobyl arch, which was damaged by a Russian drone in February 2025.

The project requires at least €500 million; prior to the conference G7 countries announced €260 million, and after the meeting the pledged amount exceeded half of the needed funds.
