European Union foreign policy chief Federica Mogherini will lead an EU delegation to Iran tomorrow, hoping to boost trade and regional peace after last year's nuclear deal.
The 24-hour trip comes just days after Italy's Prime Minister Matteo Renzi became the highest-ranking European leader to visit Tehran since July's nuclear accord.
"This visit is an important step towards building cooperative relations between the EU and Iran," Mogherini said in a statement.
She last visited Iran in July shortly after world powers — the US, Britain, China, France, Russia and Germany — agreed to lift damaging sanctions in return for Tehran accepting strict curbs to prevent it acquiring nuclear weapons. "Re-engaging with Iran is possible now," a senior EU official told reporters in Brussels this week.
Brussels is also looking to Tehran to help ease Europe's migration crisis as Iran, host to millions of Afghan refugees, is a source of onward flows to the 28-nation bloc.
"Migration is a very important theme for discussion," a senior EU official said. The official added that Mogherini, who personally helped negotiate the nuclear deal, will also seek to advance diplomatic efforts on Syria and Yemen, two regional conflicts where Iran plays a role.
