The head of Iran's nuclear effort said Sunday that the Islamic republic's nuclear program was moving ahead as scheduled, and reiterated that Teheran would not suspend uranium enrichment, the country's official news agency IRNA reported.
The comments by Reza Aqazadeh, vice president and head of Iran's Atomic Energy Organization, came just days before the Vienna-based International Atomic Energy Agency is expected to submit its latest report on Iran's nuclear program to the UN Security Council early this week.
"I confirm that our technical efforts are going ahead appropriately," IRNA quoted Aqazadeh as saying. "Improving nuclear technology and the installation and operation of 50,000 centrifuges are our aim."
Iran announced in April that it had begun to operate 3,000 centrifuges - 10 times the previously announced number - but the international community responded to the claim with skepticism. Teheran has said its ultimate goal is to have 50,000 centrifuges running at its underground facility in Natanz.
Later in April, The Associated Press obtained a confidential IAEA document saying that Iran was using 1,300 centrifuges at Natanz to enrich uranium, less than Teheran's official claim, but still significant progress. Aqazadeh did not mention a specific number of centrifuges on Sunday.
The US and some of its allies have accused Iran of secretly developing nuclear weapons and have demanded the country suspend its enrichment activities prior to any negotiations.
Both Aqazadeh and Foreign Ministry spokesman Mohammad Ali Hosseini reiterated on Sunday that Iran would not halt enrichment as a precondition to negotiations.
"We do continue this trend [enrichment] and we will not stop it," said Hosseini at his weekly press briefing.
Hosseini also confirmed Sunday that Iran's top nuclear negotiator, Ali Larijani, had agreed to meet European Union foreign policy chief Javier Solana on May 31 to discuss the deadlock over Teheran's nuclear program.
Solana last held talks in April with Larijani, who said at the time they had come closer to a "united view" on how to break the stalemate.
