Officials from Donald Trump’s transition team have informed European officials that the new US president will require NATO member states to increase their defense spending to 5% of GDP. While, according to the same sources cited by the Financial Times, Trump plans to continue providing military aid to Ukraine.

The FT reports that close foreign policy advisers to the incoming US president briefed senior European officials on his intentions this month.

US NATO allies are already in talks to raise the target to 3 percent, but many member states are concerned about the difficult fiscal decisions that would be required to raise that figure.

During his campaign, Trump said he would cut off aid to Ukraine, force Kiev to the negotiating table with Russia, and signaled that the U.S. would not defend Europe if NATO countries did not increase their defense spending.

However, according to the same sources, Trump now intends to keep US military supplies in Kiev after his inauguration, according to three people briefed on the discussions with Western officials.

At the same time, Trump will demand that NATO countries more than double the 2% defense spending target that only 23 of the alliance’s 32 members currently meet – to 5%, the Financial Times reports.

The same sources told the FT they believe Trump would settle for 3.5% and that he plans to explicitly link higher defense spending to the offer of more favorable trade terms.

Key European NATO allies – including France, Germany, the United Kingdom, Italy and Poland – met with NATO Secretary General Mark Rutte and Ukrainian President Volodymyr Zelensky in Brussels on Wednesday night to discuss how Europe will adjust defense policies in response to Trump’s return.

German Chancellor Olaf Scholz had a separate phone call with Trump on Thursday during a summit of EU leaders. Solz later told reporters that he was “fairly confident that the US and Europe will continue their support for Ukraine.”

While Trump still believes Ukraine should never join NATO and wants an immediate end to the conflict, the president-elect believes arming Kiev after the ceasefire would ensure “peace through strength.”

After 24 hours of meetings with NATO and EU leaders in Brussels this week, Zelensky said on Thursday that European commitments to defend Ukraine “would not be sufficient” without US involvement.
