President-elect Donald Trump has tossed expansionist rhetoric at U.S. allies and potential adversaries with arguments that the frontiers of American power need to be extended into Canada and the Danish territory of Greenland,

The European Union will not let other nations attack its sovereign borders, France's foreign minister said on Wednesday, responding to comments by U.S. President-elect Donald Trump on taking over Greenland.

European leaders expressed their confusion and pushed back Wednesday against President-elect Donald Trump's refusal to rule out using military force to take over Greenland.

French Foreign Minister Jean-Noël Barrot on Wednesday said the European Union will not permit President-elect Trump to attempt to take Greenland by military force.

France and Germany on Wednesday warned Donald Trump against threatening "sovereign borders" after the US president-elect refused to rule out military action to take Greenland, an autonomous territory of European Union member Denmark.

Denmark's prime minister said Thursday she had reached out to President-elect Donald Trump following his remarks about taking control of Greenland.

European leaders reacted to Trump's statement at a press conference on Tuesday that he would not rule out military action to take control of Greenland. He had earlier vowed to slap high tariffs on Denmark if it refused to cede its autonomous territory.

After Denmark, France and Germany have strongly condemned Donald Trump's controversial Greenland ambitions, with leaders from both countries declaring that the territory rightfully belongs to the European Union.
