TEHRAN, Iran — Iran's top nuclear negotiator said his country is ready to hold talks with world powers to ease fears over its nuclear activities and has prepared a revised package of proposals for Western countries, state TV reported today.

Despite the suggestion of possible international cooperation, parliament sent a defiant message to the world by supporting President Mahmoud Ahmadinejad's nominee for defense minister, who is under an international arrest warrant for the 1994 bombing of a Jewish center in Argentina that killed 85 people.

Nuclear negotiator Saeed Jalili told reporters of the country's new proposals a day before a meeting in Germany of the six countries trying to address concerns about Iran's nuclear program, the U.S., France, Britain, Russia, China and Germany.

"Iran has prepared to present its revised package of proposals ... and is ready to hold talks with world powers ... in order to ease common concerns in the international arena," the TV quoted Jalili as telling reporters.

The U.S. has given Iran a deadline of the end of September to take up an offer of nuclear talks with six world powers and enjoy trade incentives should it suspend uranium enrichment activities. If not, Iran could face harsher sanctions.
