European Council President Antonio Costa spoke by phone with Spanish Prime Minister Pedro Sánchez to reaffirm the European Union’s full support for Spain. The conversation came after U.S. President Donald Trump threatened to halt all trade with Spain for refusing to allow the use of its military bases in a mission related to Iran.

In a post on social media platform X, Costa said he had expressed the EU’s full solidarity with Spain. He added that the Union would always ensure the complete protection of its member states’ interests, while reiterating its commitment to international law and the global rules-based order.

The exchange has brought renewed attention to diplomatic tensions between the European Union and the United States following Trump’s warning, highlighting potential strains in transatlantic relations.
