A group of NATO member states has issued a joint statement criticizing U.S. President Donald Trump’s threat to impose tariffs, warning that the move could undermine transatlantic relations and increase the risk of political and economic tension.

The statement was signed by Denmark, Finland, France, Germany, the Netherlands, Sweden, and the United Kingdom, all of which expressed concern that potential trade measures against allied nations would weaken cooperation at a time of heightened global uncertainty.

According to the signatories, the proposed tariffs risk damaging long-standing partnerships between the United States and its European allies. They emphasized that trade disputes among NATO members could spill over into broader diplomatic and security relations, complicating coordination within the alliance.

The countries said that economic pressure between allies runs counter to the principles of cooperation that underpin NATO and transatlantic ties. They also warned that tariffs could have negative consequences for businesses, supply chains, and consumers on both sides of the Atlantic.

President Trump has repeatedly argued that tariffs are a necessary tool to protect American industries and correct what he describes as unfair trade practices. However, European allies have countered that such measures against partner nations would be destabilizing and could provoke retaliatory action.

The joint statement reflects growing concern in Europe about the potential impact of U.S. trade policy on diplomatic unity, particularly within NATO, which is traditionally focused on collective security rather than economic confrontation.
