WASHINGTON, Sept. 23 (Xinhua) -- The United States said Monday that it hopes the new Iranian government will engage substantively with the international community to reach a diplomatic solution to Iran's nuclear program.
The U.S. government also asks Iran to cooperate fully with the International Atomic Energy Agency (IAEA) in its investigation, State Department spokesperson Jen Psaki said in a statement.
"We remain ready to work with Iran should the (President Hassan) Rouhani administration choose to engage seriously," said Psaki.
On the same day, White House spokesman Jay Carney said Washington is "open to engagement with the Iranian government at a variety of levels provided that they will follow through on their commitments to address the international community's concerns over their nuclear program."
However, Carney said there's no meeting scheduled for U.S President Barack Obama with Rouhani at the UN General Assembly, which both leaders will attend this week.
Carney also mentioned that Secretary of State John Kerry will meet his P5-plus-1 counterparts, including permanent UN Security Council members and Germany, as well as Iranian Foreign Minister Mohammad Javad Zarif, during the UN General Assembly in New York.
"That's an opportunity for us to reaffirm, together with our P5- plus-1 partners, the importance of Iran coming in line with international obligations," said Carney.
Psaki said Kerry welcomes Zarif's commitment to a substantive response and to his agreement to meeting with his counterparts of the P5-plus-1, coordinated by EU High Representative Catherine Ashton, to discuss the nuclear program.
The U.S.-led Western countries have imposed crippling sanctions against Iran over its nuclear program, which they suspect as a attempt to acquire a nuclear weapon. They even threaten to resort to the use of force to prevent Iran from becoming a nuclear-armed country. But Tehran insists its nuclear program is only for the purpose of scientific research and civil energy use.
