Gavin Grey: European correspondent discusses growing tension around Trump's demands for Greenland

Europe may be on the cusp of implementing a never-before-used law, to turn up the heat on the United States.  President Donald Trump's announced increasing tariffs on eight countries starting next month, unless a deal allowing him to buy Greenland is reached.  European leaders have condemned the decision, with France now set to urge the EU to enact its anti-coercion instrument,  if the tariffs go ahead. Gavin Grey told Andrew Dickens that the international economic counter-measures will enhance their retaliation, within international law.  He says no one quite knows what it means as it's never been needed until now, adding things are getting very serious.  LISTEN ABOVESee omnystudio.com/listener for privacy information.
