Iran Saturday said it had yet to receive any new offer by the five permanent members of the UN Security Council and Germany that would "benefit" it for cooperating with the international community over the nuclear issue, reported dpa.
"We have not received anything in this regard yet," Foreign Minister Manouchehr Mottaki told reporters in Tehran.
An offer was worked out in a meeting of foreign ministers from six states on Friday in London, updating a similar move made by the group in June 2006, and which outlined the possibilities of technical assistance if Iran gives up its enrichment programme.
"But the relevant sides are perfectly aware of the forbidden zone and that the offer should in no way enter this zone," Mottaki said.
He did not elaborate - but Iran considers any international demand to suspend its uranium enrichment programme as the "red line" and non-negotiable.
The five veto powers and Germany consider enrichment suspension as the main condition to resume talks with Iran.
Iran has always insisted that its nuclear programme is intended purely for civil electricity generation and in line with all international regulations, and not - as feared by the West - for developing a nuclear weapon.
