Iran will not trade its "dignity" in its nuclear programme, President Mahmoud Ahmadinejad said on Wednesday, days ahead of a visit by the EU foreign policy chief to offer Tehran a new incentives package.

"They think they can trample on the Iranian nation's dignity with such things," the ISNA news agency quoted Ahmadinejad as saying in a speech in the province of Chaharmahal Bakhtiari, referring to such incentives offers.

"We will not trade our dignity with anything.

"If they want to give us something, then they should sell it and we will buy it."

Ahmadinejad's comments appear to be his latest affirmation Iran has no intention of halting sensitive uranium enrichment activities in its nuclear drive, which Western countries fear could be used to make an atomic bomb.

EU foreign policy chief Javier Solana is due in Tehran at the weekend for talks aimed at convincing Iran to suspend uranium enrichment in exchange for an incentives package offered by world powers.
