European leaders are expected to endorse measures to boost defense spending and pledge continued support for Kyiv in a summit on Thursday in Brussels.
Delegations at the summit are slated to discuss EU Commission President Ursula von der Leyen’s €800 billion ($864 billion) “ReArm Europe” plan.
Leaders of the European Union’s 27 member-states are due to be joined by Ukrainian President Volodymyr Zelenskyy.
The meeting comes after US President Donald Trump’s decision to suspend military aid to Ukraine. He has also called for European countries to take more responsibility for security within the NATO military alliance.
The night before the summit, Macron reiterated his support for plans to reduce the EU’s dependence on Washington.
“I want to believe that the United States will stand by us. But we have to be ready if that is not the case,” he said.
