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

General Mark Rutte and Danish Prime Minister Mette Frederiksen agreed at a meeting on Tuesday that allies need to focus on strengthening defences in the Arctic, a source familiar with the talks told Reuters.

Trump has shown interest in making Greenland part of the US and has not dismissed the use of military or economic power.

Frederiksen will meet German Chancellor Olaf Scholz in Berlin, French President Emmanuel Macron in Paris and NATO Secretary-General Mark Rutte in Brussels, during a whirlwind day of international diplomacy as Trump threatens to upend the polar security architecture.

The poll, which surveyed 497 Greenlandic citizens, revealed that 45 percent of respondents said they view Trump's interest in their territory as a threat, while only 8 percent would accept a U.S. passport if given the choice between American and Danish citizenship.

Danish Prime Minister Mette Frederiksen sought to drum up support from European allies to stand up to Donald Trump’s efforts to appropriate Greenland, as she tried to project unity while avoiding antagonizing the US president.

The Danish PM's tour of three capitals betrayed the nervousness felt in Denmark over Trump's repeated comments.

Trump’s bid for the Arctic territory was laughed off as a joke. Now, it’s gaining traction and provoking jitters in Europe.

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.

A new poll shows that 85% of Greenlanders oppose becoming part of the US, with only 6% in favor and 9% undecided. Danish Prime Minister Mette Frederiksen has reinforced support from European and Nordic allies,
