How Will Negotiations Proceed in Iran?

It's not like Iran has been a positive example of negotiating in good faith, but now there's a report that Western powers snubbed Iran's offer of talks:

Iran's U.N. ambassador said on Monday that six world powers have never responded to Tehran's proposal for negotiations without pre-conditions aimed at resolving its nuclear stand-off with the West.
Instead, Iranian Ambassador Mohammad Khazaee told a meeting of the U.N. General Assembly, a small group of countries continued to insist that Iran halt its uranium enrichment program, a demand that he said violated international law.
'The 5 1 Group has yet to provide its response to Iran's proposed package,' he said, referring to a proposal for talks delivered in May to the five permanent members of the U.N. Security Council and Germany.
