European Union foreign policy chief Josep Borrell was headed to Tehran on Friday for a surprise visit that could breathe new life into stalled talks on reviving the 2015 Iran nuclear deal. Borrell was due to arrive in the Iranian capital at night to meet Foreign Minister Hossein Amir-Abdollahian and other officials, Iran’s foreign ministry spokesman Saeed Khatibzadeh said. “Diplomacy is the only way to go back to full implementation of the deal and to reverse current tensions,” Borrell tweeted as the EU confirmed his two-day trip in a statement.

The landmark deal has been hanging by a thread since 2018, when then US president Donald Trump unilaterally withdrew from the accord and began imposing crippling economic sanctions on America’s arch enemy.
