Iran started negotiations with the five powers that, along the U.S., signed the Joint Comprehensive Plan of Action in 2015. The talks were held in Vienna and Iran’s President Hassan Rouhani said they were a success and that they opened a new chapter in efforts to save the so-called Iran nuclear deal. If an agreement is reached on Iran’ nuclear plans thanks to the negotiations, around 2 million bpd of Iranian crude could be added to OPEC’s total.
