Denmark has implemented a special “night watch” at its Foreign Ministry in Copenhagen in response to US President Donald Trump’s threats to annex Greenland, the semi-autonomous Danish territory, according to a new report published on Wednesday.

Trump has said he would not rule out taking the island by force, saying the United States must control the territory for national security.

“We need Greenland badly,” Trump told NBC’s Kristen Welker in May.

This rhetoric has apparently unsettled Denmark, which has repeatedly said that the island is “not for sale,” now prompting the country to take further action.

A report from Politiken newspaper cited by The Guardian said the Danish Foreign Ministry established daily “night watch” starting at 5 p.m. local time to ensure the Scandinavian country is prepared to respond to potential emergencies. The ministry then circulates a morning briefing with Danish government departments detailing any relevant overnight statements or developments, according to The Guardian.

“It’s fair to say that the situation in Greenland and the time difference between Denmark and the United States were quite an important factor in introducing this agreement during the spring,” a source close to the Foreign Office told The Guardian.

This comes as top officials from the United States, Denmark and Greenland will meet in Nuuk next month, marking the first official three-way talks since Trump’s push to acquire the island, Bloomberg and Politiken reported.

Earlier this month, Danish Foreign Minister Lars Løkke Rasmussen said he had warned the US ambassador to Denmark, Ken Howery, to stay away from Greenland, according to Politico.

“Yes, I should. [keep his hands off Greenland]and so should the United States in general, and Americans know this very well,” Rasmussen said, according to the outlet.
