AMSTERDAM, Jan 18 (Reuters) - The Netherlands' foreign minister on Sunday said that U.S. President Donald Trump's threat to impose new tariffs on European allies until they agree to sell Greenland to the United States is "blackmail".
"It's blackmail what he's doing ... and it's not necessary. It doesn't help the alliance (NATO) and it also doesn't help Greenland," David van Weel said in an interview on Dutch television.
