"After repeated requests from the Iraqis, we are ready to assist," Ali Larijani said.
He said Iran was expecting new proposals to reflect its nuclear progress.
"Of course we will welcome any plan which would not include any illogical or unreasonable conditions," he said, adding that, since Iran developed industrial production of nuclear fuel, "new proposals" would be in order.
In the coming days, Larijani will meet with EU foreign policy chief Javier Solana again, after cautious progress was reached during talks April 25-26, in the Turkish capital Ankara, to try to end a nuclear standoff around Tehran's controversial nuclear program.
"We have agreed to meet [with Solana] in two weeks but the place has yet to be determined," he said.
Iran has been at the center of international concerns over its nuclear program, which some countries, particularly the United States, suspect is geared toward nuclear weapons development. Tehran has consistently denied the claims, saying it needs nuclear power for civilian purposes. On April 9, Iranian President Mahmoud Ahmadihejad claimed that industrial production of civilian-grade nuclear fuel was being started.
"The world should know that today Iran has become one of the countries that had mastered industrial scale production of nuclear fuel, and we intend to exercise our rights in the nuclear sphere in full," Ahmadinejad said at a meeting with the residents of the province of Kerman.
The UN Security Council has repeatedly tried to pressure Iran over its refusal to abandon its nuclear program and most recently on March 24, tightened sanctions against the country, which Iran has consistently defied.
