President Donald Trump said Saturday the United States will impose new tariffs on several European countries unless a deal is reached for the purchase of Greenland, escalating his long-running push for US control of the Arctic territory.

Trump said Saturday he will impose a 10% tariff on “on any and all goods” from Denmark, Germany, the United Kingdom, France and other countries starting February 1, increasing to 25% on June 1, until an agreement is reached.

“We have subsidized Denmark, and all of the Countries of the European Union, and others, for many years by not charging them Tariffs, or any other forms of remuneration,” Trump wrote in a Truth Social post. “Now, after Centuries, it is time for Denmark to give back — World Peace is at stake!”

Trump argued that Greenland is central to US and global security and said Denmark’s defenses were insufficient. He warned that the nations’ deployment of small numbers of military personnel to Greenland amounted to “a very dangerous situation for the Safety, Security, and Survival of our Planet.”
