Germany plans to halve its military aid to Ukraine next year, despite concerns that U.S. support for Kyiv could potentially diminish if Republican candidate Donald Trump returns to the White House.

German aid to Ukraine will be cut to 4 billion euros ($4.35 billion) in 2025 from around 8 billion euros in 2024, according to a draft of the 2025 budget seen by Reuters.

Germany hopes Ukraine will be able to meet the bulk of its military needs with the $50 billion in loans from the proceeds of frozen Russian assets approved by the Group of Seven, and that funds earmarked for armaments will not be fully used.

"Ukraine's financing is secured for the foreseeable future thanks to European instruments and the G7 loans," German Finance Minister Christian Lindner said on Wednesday at a news conference.

Washington pushed to "front load" the loans to give Ukraine a big lump sum now.

Officials say EU leaders agreed to the idea in part because it reduces the chance of Ukraine being short of funds if Trump returns to the White House.

Alarm bells rang across Europe this week after Trump picked Senator J.D. Vance, who opposes military aid for Ukraine and warned Europe will have to rely less on the United States to defend the continent, as his candidate for vice president.

Trump sparked fierce criticism from Western officials for suggesting he would not protect countries that failed to meet the transatlantic military alliance's defence spending targets and would even encourage Russia to attack them.

Germany has faced criticism for repeatedly missing a NATO target of spending 2% of its economic output on defence.
