Donald Trump confirmed on Monday that his eldest son will visit Greenland, as the president-elect increasingly called for the US to control the autonomous territory owned by Denmark.

“I hear the people of Greenland are ‘MAGA,'” Trump wrote on his social media platform. “My son Don Jr. and various representatives will travel there to visit some of the most beautiful areas and attractions. Greenland is an incredible place and the people will benefit enormously from it if and when it becomes part of our nation. “We will protect and cherish it from a very vicious outside world.”

The post appeared alongside a video clip of a person saying that if he could say anything to Trump, he would tell him to “buy Greenland.”

Donald Trump Jr. told Fox News, which first reported his upcoming trip: “As someone who has traveled to some fascinating places around the world as a nature lover, I’m excited to stop in Greenland this week for a bit To have fun.”

The visit comes after the president-elect suggested the US should open the door to purchasing the island. Trump expressed interest in the area during his first term.

Last month, Trump called ownership and control of Greenland “an absolute necessity” for the United States

According to Reuters, the island’s prime minister, Múte Egede, said the area “is not for sale and will never be for sale.”

Trump has also expressed other signs of his interest in expanding U.S. territory in recent weeks, claiming his new administration could take control of the Panama Canal.

Panamanian President José Raúl Mulino rejected the idea, saying in a video on social media last month that “the sovereignty and independence of our country are non-negotiable.”

Trump has also repeatedly suggested that the United States could annex Canada as its 51st state.
