The EU and Nato have taken a vow of silence over Greenland after Denmark requested its key allies refrain from reacting to Donald Trump’s threats to seize the Arctic island.

The European Union is "not negotiating" on Greenland, EU's foreign policy chief Kaja Kallas said on Monday, amid claims by U.S. President Donald Trump that the United States needs to control Greenland for security purposes.

European Union foreign policy chief Kaja Kallas said Monday that Europe is “not negotiating” with the United States over control of Greenland, as President Trump continues to insist that acquiring the self-governing territory of Denmark is necessary for American national security.

The Defense Ministry in Copenhagen said those will include three new Arctic naval vessels, two additional long-range surveillance drones and satellite capacity.

Denmark said on Monday it would spend 14.6 billion Danish kroner ($2.05 billion) boosting its military capabilities in the Arctic – a decision that comes amid continuing furor following US President Donald Trump’s renewed interest in controlling Greenland,

The move comes after President Donald Trump voiced his desire to acquire Greenland and refused to rule out using military force.
