On the 19th of the month, seven nations which include France, the UK, Germany, Italy, the Netherlands, Japan, and Canada issued a joint statement affirming their readiness to contribute to the security of the Strait of Hormuz. This declaration comes in light of recent attacks by Iran on unarmed commercial ships and civilian infrastructure in the Gulf region, which were condemned in the statement. While the nations expressed their intent to ensure the safety of passage through the Strait, they emphasized that military involvement would not occur until after active conflicts have ceased in the area.

The statement reflects pressure from U.S. President Donald Trump on European allies, as well as South Korea and Japan, to send naval forces to the Strait. Notably, South Korea did not participate in the joint announcement. Despite their readiness to assist, the nations did not provide specifics regarding the timing or manner of their potential contributions, with leaders welcoming countries that would participate in planning.

During the EU summit in Brussels, European leaders reiterated their stance against deploying military forces to the Strait amid ongoing U.S.-Iran tensions. German Chancellor Friedrich Merz and EU foreign policy chief Josep Borrell clarified that involvement would only take place once hostilities have stopped. Some leaders expressed strong resistance to Trump's demands, with Austria's Chancellor Christian Kern stating that Europe would not succumb to threats, while Spain's Prime Minister Pedro Sánchez denounced the ongoing war as illegal, highlighting its humanitarian toll including the refugee crisis.
