U.S. declines to help present nuclear deal to Iran

World powers will in the coming days offer a revised package of incentives to Iran but Washington has refused to send its own envoy to help present the deal, diplomats and a U.S. official said on Thursday.

Diplomats said the package, aimed at getting Iran to halt its nuclear work, could be delivered on Friday or over the weekend, most likely in Tehran, by the European Union's foreign policy chief, Javier Solana.

In a change from normal protocol, political directors from France, Britain, Russia and China -- permanent members of the U.N. Security Council -- and Germany would probably go with Solana, diplomats said, speaking on condition of anonymity.

But the United States, which is involved with major powers in the negotiations, has made clear it will not join the mission to present the offer, which is expected to be given to Iranian Foreign Minister Manouchehr Mottaki.

"We are not going to be going to Tehran. But, again, we're still working out some of the details with our partners in the process," said State Department spokesman Sean McCormack, when asked whether the United States would also deliver the deal. More
