Trump claimed both the canal and the Danish territory are needed for U.S. “economic security.”

U.S. President-elect Donald Trump has been rebuked in recent days by the leaders of both Panama and Denmark for his insistence that the Panama Canal and Danish territory Greenland must be under American control, and his latest comments on Tuesday were expected to garner more anger—and eye-rolling—from abroad.

At a press conference at his Florida resort, Mar-a-Lago, the Republican leader refused to rule out using military force to take over the canal and Greenland.

“It might be that you’ll have to do something. The Panama Canal is vital to our country,” said Trump. “We need Greenland for national security purposes.”

He added that both the canal and Greenland, the world’s largest island and home to a U.S. military base, are needed for U.S. “economic security.”

Under President Jimmy Carter, who died late last month, the U.S. signed a treaty returning the Panama Canal Zone to Panama in 1979, and the waterway connecting the Atlantic and Pacific Oceans has been solely controlled by the Panamanian government since 1999.

Trump repeated a false claim that the canal is being “operated by China.”

Last month, after the president-elect demanded “that the Panama Canal be returned to the United States of America in full, quickly and without question,” Panamanian President José Raúl Mulino posted a video to social media in response.

“As president, I want to clearly state that every square meter of the Panama Canal and its adjoining zone is Panama’s and will remain so,” Mulino said. “The sovereignty and independence of our country is non-negotiable.”

Trump’s comments came as his son, Donald Trump Jr., joined right-wing activist Charlie Kirk and other Trump allies on a visit to Greenland.

The president-elect suggested in a social media post that the trip was made in an official capacity, writing: “The reception has been great. They, and the Free World, need safety, security, strength, and PEACE! This is a deal that must happen. MAGA. MAKE GREENLAND GREAT AGAIN!”

But Greenland officials clarified that Trump Jr. was visiting only as a “private individual” and said no representatives would be meeting with him.

Trump said at his press conference that “people really don’t even know if Denmark has any legal right to [Greenland], but if they do they should give it up because we need it for national security.”

Greenland is home to 60,000 people, and is self-ruling with its own legislature while its foreign and defense policy are controlled by Denmark. The Arctic island lies in a region where global powers are vying for military and economic control.

Trump also expressed a desire to purchase Greenland during his first term, a goal that was dismissed at the time as “absurd” by Danish Prime Minister Mette Frederiksen.

“Greenland belongs to the Greenlanders,” Frederiksen reiterated on Tuesday.
