President Donald Trump affirmed his intention to impose tariffs on European countries opposing his efforts to gain control of Greenland, stating he would "100%" follow through on the threat. The announcement comes as European allies have united in support of Greenland's sovereignty, with Denmark's foreign minister asserting that the US president cannot coerce ownership of the semi-autonomous Danish territory.

Trump's renewed commitment to tariffs, which he initially threatened in 2019, has drawn criticism and concern from European Union officials. Kaja Kallas, the EU's foreign policy chief, stated that while the bloc has "no interest to pick a fight, we will hold our ground." The proposed tariffs target goods arriving in the US from the UK and seven other NATO-allied countries.

The UK's Foreign Secretary, Yvette Cooper, reiterated the UK's stance that the future of Greenland should be determined by "Greenlanders and for the Danes alone." On Monday, Trump declined to rule out the use of force in pursuing his objectives regarding Greenland.

In a post on Truth Social early Tuesday morning, Trump mentioned a "very good telephone call" with NATO Secretary General Mark Rutte and indicated an upcoming meeting "of various parties" in Switzerland this week. The specific agenda of the meeting was not disclosed.

The initial proposal to purchase Greenland was made by Trump in 2019, which was met with strong opposition from both Danish and Greenlandic officials. Greenland, while part of the Kingdom of Denmark, possesses significant autonomy, managing its internal affairs. The island is strategically important due to its location and natural resources.

The potential imposition of tariffs raises concerns about escalating trade tensions between the US and Europe. The EU has previously indicated it would respond with retaliatory measures if the tariffs are implemented. The situation remains fluid, with diplomatic efforts ongoing to de-escalate the dispute.
