Tehran, (AFP)- Iran said on Tuesday it views its nuclear activities as a non-negotiable right, but confirmed they will be discussed in mooted talks with world powers aimed at defusing a crisis containing the seeds of a new Middle East war.

“The issue of our country’s peaceful nuclear activities will be on the agenda of talks between Iran and the P5+1 (the five permanent UN Security Council members plus Germany),” foreign ministry spokesman Ramin Mehmanparast told reporters in a televised briefing.

“Our main demand is recognition of our right to possess the (nuclear) technology for peaceful purposes,” Mehmanparast said.

“That right has been achieved, and we don’t think there is a negotiable issue regarding our nuclear activities.”

Mehmanparast’s comments came on the second day of a two-day visit by officials from the UN nuclear watchdog for talks focused on “possible military dimensions” of the nuclear programme.

The ministry spokesman said the aim of the visit by officials from the International Atomic Energy Agency was not inspections but to talk about “a framework to pursue dialogue and cooperation between Iran and the IAEA.”

An IAEA visit to Tehran late last month was inconclusive.

Tensions have risen dramatically this year over Iran’s nuclear programme, which much of the West suspects includes research to develop atomic weapons.

Israel has provoked increasing speculation it is poised to launch air strikes on Iran’s nuclear sites, raising the possibility of a wider conflict being triggered that could draw in the United States, EU nations, and Saudi Arabia.

Iran on Monday announced its military was holding exercises to boost air defences around its nuclear facilities.

Meanwhile, the European Union was studying Iran’s positive response to an offer it made late last year to revive talks with the P5+1 that collapsed in January 2011.

EU foreign policy chief Catherine Ashton said the talks could resume if Iran placed no pre-conditions on them, particularly concerning its nuclear programme.

In the more than three months it took Iran to reply to Ashton’s offer of renewed talks, Tehran has forged ahead with its nuclear activities, declaring it was adding thousands more centrifuges to its uranium enrichment activities and producing what it said was 20-percent enriched nuclear fuel.

The UN nuclear agency in November issued a report voicing strong suspicions that Iran was engaged in research for an atomic weapon and ballistic missile warhead design.

While confronting challenges on the military and diplomatic fronts, Iran is also battling with the economic pressure from Western sanctions.

On Monday, it said it could expand a halt on oil exports to the European Union, following a stoppage announced at the weekend to France and Britain, in apparent retaliation for an EU oil embargo due come into full effect in July.

“Certainly if the hostile actions of some European countries continue, the export of oil to these countries will be cut,” said Deputy Oil Minister Ahmad Qalebani, pointing the finger at Spain, Greece, Italy, Portugal, Germany and the Netherlands, Mehr news agency reported.

The European Union, though, said it could cope with any halt in Iranian supplies.

“In terms of immediate security of stocks, the EU is well stocked with oil and petroleum products to face a potential disruption of supplies,” said a spokesman for Ashton.

In Rome, French Foreign Minister Alain Juppe dismissed Tehran’s move.

“Undoubtedly, Iran is very imaginative with regards to provocation. It is not Iran that decided to cut off its deliveries, we are the ones who decided to terminate our orders,” he told reporters.

“It makes one smile,” Juppe added.

Iran exports about 20 percent of its crude — some 600,000 barrels per day — to the European Union, mostly to Italy, Spain and Greece.

After initially spiking to a nine-month high on the news about France and Britain, oil prices softened slightly.

Brent North Sea crude for April delivery shed eight cents to trade at $119.89 a barrel in Asian trade on Tuesday afternoon.

“I think with the Brent (contract), the initial panic over Iran is going away, pushing prices downwards….

“People are actually calming down after realising that this is a game of political brinksmanship from Iran,” said one analyst, Justin Harper, head of research at IG Markets Singapore.
