Von der Leyen said on Sunday evening said she had spoken with NATO Secretary-General Mark Rutte, French President Emmanuel Macron, British Prime Minister Keir Starmer, German Chancellor Friedrich Merz and Italian Prime Minister Giorgia Meloni about the latest developments.
In a post on X, she said that the leaders firmly upheld their commitment to supporting the sovereignty of Greenland and the Kingdom of Denmark
"We will always protect our strategic economic and security interests. We will face these challenges to our European solidarity with steadiness and resolve," she wrote.
Meanwhile, European Council President Antonio Costa has announced plans to convene an emergency meeting of EU leaders in the coming days, with sources indicating the summit could take place on Thursday in Brussels.
The developments follow Saturday's announcement by Trump that he would impose 10-percent tariffs on eight European nations which recently sent small military contingents to Greenland for Danish-led Arctic Endurance exercises.
The affected countries include Denmark, Norway, Sweden, France, Germany, the Netherlands, Finland and the United Kingdom.
Trump warned the tariffs would rise to 25 percent in June and remain in place until the United States reaches an agreement to purchase the island, an autonomous territory of Denmark.
Costa said consultations with member states had shown the EU was united on principles of international law, territorial integrity and national sovereignty, as well as in supporting Denmark and Greenland.
He emphasised that EU countries agreed the planned new tariffs would weaken transatlantic relations and were inconsistent with the EU-US trade agreement.
Costa added that the EU was prepared to defend against all forms of coercion while expressing readiness for continued constructive cooperation with the United States "on all issues of common interest."
EU ambassadors held an extraordinary meeting in Brussels on Sunday afternoon to discuss EU-US relations and coordinate their approach.
