Iranian President Hassan Rohani says Tehran wants international sanctions lifted on the day that a final deal curbing its nuclear program is implemented.
"We will not sign any agreements unless on the first day of the implementation of the deal all economic sanctions are totally lifted on the same day," Rouhani said during a ceremony on April 9 marking National Nuclear Technology Day.
He added that Iran wants "a win-win deal for all parties involved in the nuclear talks," referring to negotiations between Tehran and six world powers -- the United States, Russia, China, Britain, France, and Germany.
On April 2, the parties announced agreement on a framework for the deal, and they have set a June 30 deadline for a final agreement.
Insistence on the immediate removal of all sanctions would badly harm the chances for an agreement, because other countries in the talks say removal of sanctions would be contingent on steps by Iran to ease concerns it could develop nuclear weapons.
The United States has made it clear that sanctions would have to be phased out gradually.
