Senior European diplomats are set for urgent talks after US President Donald Trump announced tariffs on eight European countries. These nations include Denmark, Norway, Sweden, France, Germany, the UK, the Netherlands, and Finland. Trump's move comes over their support for Greenland, a largely autonomous territory under Denmark. He plans 10% tariffs from February 1, rising to 25% from June 1. Trump said on Truth Social the tariffs will continue "until such time as a Deal is reached for the Complete and Total purchase of Greenland." European leaders quickly condemned the threats. Italy’s Prime Minister Giorgia Meloni called the tariffs a "mistake." Dutch Foreign Minister David van Weel described the US president's threats as "blackmail." French President Emmanuel Macron said Europe will not be intimidated. He urged the EU to use its anti-coercion law, allowing punitive economic measures. The EU’s 27 ambassadors held an emergency meeting Sunday to discuss the crisis. Ursula von der Leyen and António Costa warned the tariffs would "undermine transatlantic relations and risk a dangerous downward spiral." Finland’s President Alexander Stubb said Europe stands united in supporting Denmark and Greenland. Spain’s leader Pedro Sánchez warned that a US invasion of Greenland would strengthen Russia’s position and harm Nato. EU Foreign Minister Kaja Kallas said, "If Greenland’s security is at risk, we can address this inside Nato." She warned the dispute risks distracting from helping end Russia’s war in Ukraine. Denmark’s Foreign Minister Lars Løkke Rasmussen called Trump’s surprise announcement unfortunate. He said increased military presence in Greenland aims to boost Arctic security. Trump criticized Denmark's defense efforts and called Greenland vulnerable to China and Russia. Recently, troops from targeted countries made visits to Greenland to show their commitment to Arctic security. Observers called the threats an "existential crisis" for Nato. Robert Pszczel, a former Nato official, said Trump's economic blackmail violates the North Atlantic Treaty. EU trade chief Bernd Lange urged activating the anti-coercion instrument to respond firmly. He said, "The EU cannot simply move on to business as usual."
