Tusk informed NATO Secretary General Mark Rutte of the decision, which was attributed to Poland’s high budget deficit and already heavy defence spending.
Poland is expected to continue supporting Ukraine.
Warsaw previously contributed $100 million to the programme as part of a joint package with Norway and Germany announced in December 2025.
NATO established the Prioritized Ukraine Requirements List (PURL) on 14 July 2025 in response to cuts in US support for Kyiv under the Trump administration, and the first payments came in August that year.
NATO identifies the weapons Ukraine needs and coordinates funding and deliveries, with member countries and partners paying for equipment from US manufacturers or existing US stocks.
Norway, the Netherlands, Germany and Canada are among the programme’s largest contributors.
