The White House has urged diplomatic caution after European leaders sharply criticised President Donald Trump’s tariff threats over Greenland. National Economic Council Director Kevin Hassett called for “cooler heads to prevail”, stressing the need for negotiation and measured diplomacy.
Eko Hot News reports that Hassett acknowledged strong rhetoric from both sides but emphasised that the President is focused on deal-making to secure outcomes beneficial for all parties. Trump had proposed a 10% tariff on Danish and other European goods to pressure Denmark regarding Greenland, an autonomous Arctic territory.

European leaders, however, have strongly opposed the move. British Prime Minister Keir Starmer stated that decisions regarding Greenland should rest with Denmark and its people, calling the tariff threats “completely wrong.” The European Union is reportedly considering retaliatory measures in response to the U.S. action.
Trump has warned that if no agreement is reached, tariffs could rise to 25% on June 1, 2026, affecting Denmark, the United Kingdom, Norway, Sweden, France, Germany, the Netherlands, and Finland. Analysts caution that such escalation could strain transatlantic relations and threaten global trade stability.
Experts suggest that Greenland’s strategic importance to both the U.S. and NATO allies makes negotiation preferable to confrontation. Hudson Institute senior fellow Rebeccah Heinrichs highlighted the potential for collaboration to resolve tensions while safeguarding security and economic interests.

Danish Prime Minister Mette Frederiksen reaffirmed that Europe would not be “blackmailed” by tariff threats, warning that aggressive measures could harm transatlantic cooperation and broader diplomatic ties.
The White House’s call for “cooler heads” underscores the rising diplomatic friction surrounding Greenland as global leaders monitor the situation closely, seeking a balance between economic leverage and international relations.
