The Obama administration says the election of a relative moderate as Iran's next president will not result in Washington offering Tehran a new nuclear deal.
State Department spokeswoman Jen Psaki told reporters on June 17 that Washington is open to new nuclear talks with Iran, but the United States wants Iran to respond first to an offer of sanctions relief in return for Iranian nuclear concessions.
Iranian cleric Hassan Rohani's election win has raised hopes of greater flexibility.
But Psaki noted that the ultimate decisions on Iran's nuclear program are made by Iran's Supreme Leader Ali Khamenei.
Psaki's comments come after Rohani promised "more transparency" on the country's nuclear program in hopes of easing economic sanctions, which he criticized as "brutal" and unjustified.
Rohani said it was important for Iran to improve relations with other states, especially its neighbors.
