Palm Beach, Florida - President Donald Trump on Saturday escalated his quest to acquire Greenland, threatening multiple European nations with tariffs of up to 25% until his purchase of the Danish territory is achieved.

Trump aimed his ire at Denmark, a fellow NATO member, as well as several European countries that have deployed troops in recent days to the vast, mineral-rich territory at the gateway to the Arctic with a population of 57,000.

If realized, Trump's threats against Washington's NATO partners would create unprecedented tension within the alliance.

From February 1, Denmark, Norway, Sweden, France, Germany, the United Kingdom, the Netherlands, and Finland would be subject to a 10% tariff on all goods sent to the US, Trump said in a post on Truth Social.

"On June 1st, 2026, the Tariff will be increased to 25%. This Tariff will be due and payable until such time as a Deal is reached for the Complete and Total purchase of Greenland," he wrote.

"These Countries, who are playing this very dangerous game, have put a level of risk in play that is not tenable or sustainable," Trump said.

"Therefore, it is imperative that, in order to protect Global Peace and Security, strong measures be taken so that this potentially perilous situation end quickly, and without question."

It was not immediately clear what authority the US leader would invoke to impose the threatened tariffs of up to 25%.

Since returning to the presidency, Trump has unleashed sweeping tariffs on goods from virtually all trading partners, to address what Washington says are unfair trade practices and as a tool to press governments on US concerns.
