Denmark's sovereignty is an "essential issue" for the EU, the European Council President said in an interview on Wednesday, as U.S. President Donald Trump continues to express interest in claiming Greenland for the United States.

Denmark's Prime Minister Mette Frederiksen said on Tuesday following a meeting with French President Emmanuel Macron that political leaders in Europe and beyond have given full backing to maintain respects for international borders.

It’s a problem that has plagued European governments for decades, from the credit-crunch bank bailouts of 2008 to more recent rescue packages for the likes of Lufthansa (€9 billion) and Air France–KLM (€7.7 billion), after those airlines were battered by pandemic-era lockdowns.

Europe is uniting in response to US President Donald Trump’s efforts to appropriate Greenland. Danish Prime Minister Mette Frederiksen sought to drum up support from German Chancellor Olaf Scholz in Berlin and French President Emmanuel Macron in Paris before a meeting with NATO Secretary General Mark Rutte.

German Chancellor Olaf Scholz has warned of the threat posed by hybrid warfare from Moscow after an underwater Baltic Sea cable was severed. Scholz was speaking as he met Danish Prime Minister Mette Frederiksen.

Frederiksen’s efforts have not been limited to diplomatic dashes. Denmark has announced a $2bn Arctic security plan, including new warships, drones and satellite capabilities to bolster its presence in Greenland, which is a self-governing territory within the Kingdom of Denmark.

President Trump told Denmark’s leader he wanted to take over Greenland, European officials say. Denmark has asked its E.U. allies not to inflame the situation until Mr. Trump’s intentions are clearer.
