"It depends if this proposal gets buy-in from Russia and China, and also some non-aligned countries," a Western diplomat told AFP Thursday.

A European diplomat said the proposal was "not yet on the table" and that European Union negotiators Britain, Germany and France were "exploring what flexibilities there might be with other countries to see if we might come to an agreement."

Washington, London, Paris, and Berlin will make a new offer to Iran to avoid a confrontation over its suspected nuclear weapons program, The New York Times said Thursday quoting US and European officials.

The proposal would let Iran conduct very limited nuclear activities on its territory, but would have it move all uranium enrichment processes to Russia, the officials said.

International Atomic Energy Agency (IAEA) spokeswoman Melissa Fleming said: "Dr. ElBaradei supports the efforts of the countries who are presently engaged in developing such a proposal."

She said ElBaradei "hopes that in the coming days the international community will be able to coalesce around a solution that is acceptable to all parties, including Iran."

"Dr Elbaradei has a standing invitation to visit Iran, and while he has no plans to do so at present, he is ready to travel to Iran at an appropriate time if it will help facilitate a solution," Fleming said.
