Hello, welcome to the programme.
This is News Hour from the BBC World Service.
We're coming to you live from London and I'm Paul Henley.
President Trump's threats of tariffs on eight European countries opposing his acquisition of Greenland is not being taken lying down.
European Union ambassadors are holding an emergency meeting in Brussels this afternoon and all the talk is of solidarity.
Greenland has been part of the Kingdom of Denmark since 1721.
The deputy leader of Denmark's parliament, Lars Christian Brask, told the BBC that Mr Trump's plan was a farce and that it was turning friends into enemies.
We have to put political pressure via NATO, via the EU, on the US, because this is a situation that...
sort of look like economic blackmail at least and it's damaging trade, it's thereby damaging growth and prosperity and nobody wants that.
Mr Trump says he'll introduce a 10% levy on France, Germany, the UK and the Netherlands in addition to Finland, Denmark, Sweden and Norway from next month if there is no deal for him to purchase Greenland.
The EU's foreign policy chief has said China and Russia must be having a field day over divisions being created among the Allies.
The tariff announcement followed a visit by a US congressional delegation to Denmark, which included Congressman Gregory Meeks.
He's a Democrat and he's their most senior member on the House Foreign Affairs Committee.
This is what he told NewsHour.
My trip here in Denmark today, every official has said, just tell us what you need.
