German Chancellor Olaf Scholz on Wednesday publicly called out US President-elect Donald Trump over his threat to seize control of Greenland, saying "the inviolability of borders applies to every country.

In recent weeks, Trump has ramped up his attacks on allies. He’s threatened to impose tariffs on Canada, Mexico and the European Union. He’s mocked Canada as the “51st state” and blamed Mexico for fentanyl overdoses in the U.S.

The EU's two leading members were reacting to the US president-elect's plans to acquire Denmark's autonomous territory.
