President Donald Trump announced on Saturday that tariffs would be gradually increased on products from eight NATO countries sent to the United States “until we reach an agreement on a complete and comprehensive purchase of Greenland.”
Tariffs targeting Denmark, Norway, Sweden, France, Germany, the United Kingdom, the Netherlands and Finland will begin at 10% starting February 1, President Trump said in a post on Truth Social.
The president said tariffs would increase to a maximum of 25% on June 1.
His post suggested the new tariffs were being imposed in response to European allies moving troops into Greenland. Their move comes as the Trump administration is considering using the U.S. military as part of its efforts to gain territory in Denmark.
President Trump wrote that eight countries “traveled to Greenland for unknown purposes.” “This is a very dangerous situation for the safety, security, and survival of our planet.”
The day before, President Trump suggested he might pursue a tariff strategy against Greenland similar to that used to force foreign countries to change drug prices.
“We might do that with Greenland, too. We might impose tariffs on countries that don’t agree with Greenland, because we need Greenland for our national security,” he said at the White House on Friday.
President Trump’s latest tariff threats have placed further strain on NATO, the 32-nation military alliance created after World War II. The basis of the alliance is the agreement that an attack on any member state is considered an attack on all members.
