Trump threatens new tariffs on European allies over Greenland until deal reached, as thousands protest

Washington, DC, and Nuuk, Greenland (CNN) — 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 ruled by Denmark.

Trump said he will impose a 10% tariff 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 didn’t specify the nature of the tariffs he plans to impose on the European countries, nor whether the 10% tariff is on top of what they’re already paying. CNN has reached out to the White House for comment.

Trump argued in his social media post 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.”

While it is not necessarily unusual for NATO countries to conduct such exercises, the timing represents a significant show of support for Denmark and underscores the tensions within the transatlantic alliance.

Trump added that the US has sought to acquire Greenland for more than 150 years and argued that modern weapons systems and missile defense projects, including the “Golden Dome,” make control of the territory especially important.

His repeated statements have strained diplomatic relations between the US and Denmark, which owns the territory but gives the local population the right to self-determination, while also prompting condemnation from NATO’s European member states.

How Trump could impose tariffs

The tariffs Trump threatened would likely be imposed under the International Emergency Economic Powers Act — the law the president has cited in previous executive orders that outlined levies used to bend countries to his will.

The Supreme Court is expected to rule in the coming weeks on whether Trump can use the emergency powers granted in the International Emergency Economic Powers Act to impose tariffs. Justices have appeared skeptical of the Trump administration’s use of that law, because it makes no mention of tariffs.

If Trump is unable to use emergency powers to impose tariffs, he has other laws he could use, but those tend to be limited in their scope and length of time they can be employed. That may limit tariffs’ usefulness as a device to pressure other countries into giving Trump what he wants — such as Greenland.

The countries Trump threatened are already subject to tariffs of at least 10%. It’s unclear whether the 10% tariff Trump announced Saturday is on top of what they’re already paying and whether preexisting deals with the United Kingdom and European Union would supercede the new tariffs. Those deals, reached last year, carve out a number of exceptions to the rates for imports to the United States.

Protesters rally against Trump’s threats

Meanwhile, protesters demonstrated in Greenland and Denmark against Trump’s threats to take over the Arctic island and demanded its citizens should be allowed to determine their own future.

In Denmark, thousands turned out in the cities of Copenhagen, Aarhus, Aalborg and Odense to stand in solidarity with the Greenlandic population.

A protest kicked off later in Greenland’s capital of Nuuk. Just before 2 p.m. local time, there was an estimated crowd of 5,000 — a large proportion of the island’s population of 56,000. People waved banners saying, “Yankee go home” and “Greenland is already great.”

“We are demonstrating against American statements and ambitions to annex Greenland,” said Camilla Siezing, chair of the Joint Association Inuit, one of the Greenlandic organizations involved in planning the protests. “We demand respect for the Danish Realm and for Greenland’s right to self-determination. Hopefully, we can show that we are many who support Greenland.”

In Greenland on Saturday, protesters were similarly defiant. Asked what her message to the US president was, one female protester in Nuuk, who didn’t give her name, told CNN, “We are not for sale.”

Another protester named Patricia said, “We have seen what (Trump) does in Venezuela and Iran. He doesn’t respect anything. He just takes what he thinks is his. … He misuses his power.”

A male protester, who didn’t give his name, said, “We do not accept this kind of aggression,” referring to Trump’s threats on Greenland.

Amid the escalating situation, a US delegation of bipartisan lawmakers traveled to Copenhagen to meet with leaders from Denmark and Greenland.

In a news conference on Saturday, Democratic Sen. Chris Coons, who is leading the delegation, said the Trump administration’s “tempo of statements” around Greenland’s potential acquisition was not constructive.

Coons also expressed his respect for the Indigenous people of Greenland, telling journalists that it was a “remote and difficult place to live, and that the population of Greenland has managed to carve out of an exceptionally difficult environment, a culture and an approach to living that is worthy of deep respect.”

The US lawmaker sought to highlight the partnership between the US and Denmark, including in the military sphere, saying that the delegation would visit a cemetery later Saturday to lay a wreath for Danish soldiers who fell fighting alongside American troops in conflicts such as the war in Afghanistan.

Even lawmakers within the Republican Party have expressed their opposition to Trump’s plans for Greenland.

Rep. Don Bacon, a Nebraska Republican, told CNN that Trump’s threats to other NATO countries were “shameful.”

“The fact that Greenland is part of NATO’s umbrella gives the president all he needs to put more bases there.”

The push also faces stiff headwinds with the American public: Three-quarters of Americans say they oppose the United States attempting to take control of Greenland, according to a recent CNN poll conducted by SSRS.
