The European Union has formally joined the US-led Operation Economic Outcast, aligning with Washington’s efforts to intensify economic and financial pressure on Iran over its nuclear and ballistic missile programmes, regional activities and military support for Russia.

In a statement, the EU said it has repeatedly urged Tehran to scale back its nuclear and missile programmes, end activities it considers destabilising in the Middle East and Europe, stop providing military assistance to Russia in its war against Ukraine, and halt what it described as violence and repression against the Iranian population.

Despite the tougher measures, Brussels stressed that diplomacy remains essential to achieving a peaceful settlement with Iran, restoring stability in the region and protecting freedom of navigation through the Strait of Hormuz, one of the world’s most important maritime shipping routes.

The EU said it has already imposed extensive sanctions designed to restrict Iran’s ability to use international financial and economic systems to support activities that Brussels considers threatening to regional and international security.

The bloc added that it was prepared to introduce further measures if necessary to protect European security and interests, including ensuring the safe passage of vessels through the Strait of Hormuz.

The EU also welcomed international efforts to pressure Iran into ending its destabilising activities and engaging in peace negotiations “in good faith”. It said additional economic pressure under the US-led operation could contribute to those efforts.

“The EU will continue to work closely with the United States and other G7 and international partners to maintain pressure on Iran and contribute to de-escalation and regional stability,” the statement said.
US Treasury Secretary Scott Bessent welcomed the EU’s decision, calling it an important demonstration of cooperation between Washington and its European allies.

“The European Union has officially joined Operation Economic Outcast and we appreciate their strong and early stance,” Bessent said.

He said the United States would continue working with its partners to prevent Tehran from using the international financial system to fund its nuclear and weapons programmes and support allied armed groups.

Bessent added that Washington and its allies would maintain pressure until Iran’s remaining access to international financial resources was significantly restricted.
