Iran is ready for "constructive dialogue" with world powers on its nuclear drive, local news agencies Wednesday quoted chief nuclear negotiator Said Jalili as saying.
"By updating last year's package, the Islamic republic is announcing its readiness for constructive dialogue and interaction," he said.
President Mahmoud Ahmadinejad said last week Iran would offer a new package for negotiations aimed at resolving the nuclear standoff, after world powers called for dialogue.
Monday, Ahmadinejad said at a press conference in Geneva that he welcomed the shift in U.S. policy towards Tehran after three decades of severed ties, describing it as "necessary" but that he was awaiting "practical changes."
However, he indicated that Iran wouldn't stop its nuclear program.
Western powers fear Iran's nuclear drive could be a cover for efforts to build an atomic bomb, but the government insists it is aimed purely at generating electricity for a growing population.
Last week, Ahmadinejad said Iran's package of proposals would be presented to the so-called P5+1 group - U.N. Security Council permanent members the U.K., China, France, Russia and the U.S. plus Germany.
He said the package was a new version of proposals offered by Iran in May 2008, which it described as an all-embracing attempt to solve the problems of the world, and suggested setting up consortiums to enrich uranium and manufacturing nuclear fuel, including one in Iran.
