U.S. President Donald Trump said Saturday that he would charge a 10 per cent import tax starting in February on goods from eight European nations because of opposition to U.S. control of Greenland.

He said in a social media post that Denmark, Norway, Sweden, France, Germany, the United Kingdom, the Netherlands, and Finland would face the tariff, which would be raised to 25% on June 1 if a deal is not in place for “the Complete and Total purchase of Greenland” by the United States.

Earlier Saturday, hundreds of people in Greenland’s capital braved near-freezing temperatures, rain and icy streets to march in a rally in support of their own self-governance in the face of threats of an American takeover.
