The EU’s top diplomat Kaja Kallas defended Greenlanders’ right to self-determination in her inaugural speech to the European Parliament on Tuesday.

Her address comes in the wake of U.S. President Donald Trump’s ongoing threats to seize the self-ruling Danish territory.

“Any decisions over Greenland’s future should be decided … by the people of Greenland,” Kallas said. “The only way to maintain the rules-based world order is the full respect of the principles of sovereignty, territorial integrity and sanctity of borders.”

Kallas reaffirmed the EU’s collaboration with the Arctic island, adding that the bloc “fully supports” its objectives in education, green growth, raw materials, renewable energy and security.

Since his reelection last November, Trump has repeatedly said he wants the U.S. to acquire Greenland for “international safety and security.”

“We need it. We have to have it,” Trump said in a radio interview in March. During the same month, Vice President JD Vance visited a U.S. Space Force base on the island, which boasts significant mineral reserves.

Both Greenland and Denmark have reputedly said the Arctic island is not for sale, with Greenland’s former Prime Minister Múte Bourup Egede saying that it is up to its people to decide their own future.

Earlier in January, Kallas said that the EU was “not negotiating” with the U.S. on Greenland.
