European Union diplomats have suggested that the EU should be prepared to go as far as doubling its military aid to Ukraine this year to 40 billion euros ($43 billion) if necessary.

The diplomats stated this in a discussion paper by the bloc’s diplomatic service.

The paper also said that each EU country participating in the effort should contribute in line with its economic weight.

With the future of US backing for Ukraine uncertain, EU countries have expressed a broad willingness to continue supporting the country in the war triggered by Russia’s 2022 invasion, but diplomats say several states oppose fixed targets.

According to the paper, the EU gave about 20 billion euros in military aid to Ukraine last year and encourages EU countries to do at least the same again in 2025, with the total potentially reaching 40 billion euros, depending on Kyiv’s needs.

EU leaders are reportedly likely to discuss the proposal by the European External Action Service, EEAS, headed by former Estonian Prime Minister Kaja Kallas, at a summit next week.

The EEAS non-paper, diplomatic jargon for a discussion document rather than a formal proposal, suggests that leaders agree as a first step next week to provide 2 million rounds of large-calibre artillery ammunition to Kyiv this year.

The paper suggests that some of the costs of the plan could come from a scheme that takes windfall profits from Russian assets inside the EU and uses them for the benefit of Ukraine.

Hungary, whose prime minister Viktor Orban has criticised EU sanctions on Russia and military assistance to Ukraine, said on Friday that his country should contribute funds to a common EU defence policy, but not agree to joint EU borrowing for defence.
