Despite the threat of UN sanctions over Tehran's refusal to hold back its nuclear programme, Ahmadinejad said that long term target of Iran should be to install 60,000 centrifuges to enrich uranium.

Iran has said it is looking to install 3,000 centrifuges by March 2007, in itself a massive step from the two cascades of 164 centrifuges apiece it has currently at its Natanz plant to enrich uranium on a research scale.

"We want to produce nuclear fuel and eventually we should go for 60,000 centrifuges. We should continue along this path. We are at the beginning of the wave," Ahmadinejad told a news conference.

His comments reaffirmed Iran's insistence that it wants to produce its own nuclear fuel on Iranian soil and will not renounce its right to uranium enrichment, a process the West fears could be diverted to make a nuclear bomb.

The remarks came as the United States and European powers seek to find agreement for a UN draft resolution that would impose sanctions on Iran over its failure to suspend uranium enrichment.

Enrichment is carried out in lines of centrifuges called cascades and is used to make the fuel for civilian nuclear reactors. But in highly enriched form, the uranium can be used to make a nuclear bomb.

Building tens of thousands of centrifuges would take Iran's enrichment programme from its current research level to one where it could produce nuclear fuel on an industrial scale.

World powers wanted Iran to suspend enrichment as a prelude to full-scale negotiations over its atomic programme, a demand that has been repeatedly rejected by Iran.

"The question of a suspension has now been passed," Ahmadinejad said.

But the president shrugged off the prospect of sanctions. "If they put in place sanctions a new financial order will be put in place."

Iran's arch-enemy the United States accuses it of seeking nuclear weapons, but Tehran insists its atomic programme is solely aimed at generating energy.

The president confidently announced he would soon send a personal message to the American people, boasting to suspicious world powers that there now was no holding back the Iranian nuclear programme

"I will soon send a message to the American people. I am in the process of preparing it," Ahmadinejad said.

"The message will elaborate upon the viewpoints of the Iranian nation, because many Americans asked me for it."

Ahmadinejad has already made message-writing part of his personal style, firing off missives to US President George W. Bush and German Chancellor Angela Merkel, that were greeted with frigidity by both parties.

The president gave no further details of the contents of the latest missive, which would come at a time of mounting calls in the United States for contacts with Iran to stabilise neighbouring Iraq.

"The great powers have tried to prevent our people from achieving their rights in nuclear material," he said.

"With the help of God and the resistance of the people, Iran is completely mastering the nuclear fuel cycle and time is playing in favour of Iran. Many countries have agreed to live with an Iran that has mastered enrichment.

"This year I hope will be able to have the great celebration of the nuclearisation of Iran," he added.

When asked later to clarify this comment, Ahmadinejad said it would be a "celebration of confirmation of Iran's right in nuclear material."

"We need time before we can arrive at a stage where we can make nuclear fuel for a power station. And yes, it will take time."
