Iran said on Monday the UN nuclear watchdog was suffering a crisis of "moral authority and credibility", underlining worsening relations between Tehran and the International Atomic Energy Agency. In a speech to IAEA member states including the United States, Iran's nuclear energy chief Ali Akbar Salehi also voiced continued defiance over international demands that the Islamic state stop work the West suspects is aimed at making atom bombs.
"The uncivilised double-track approach of threat and dialogue cannot be conducive and fruitful," he said, referring to the West's policy of imposing sanctions on Iran while offering incentives for it to back down in the eight-year row.
Speaking shortly afterwards at the same annual assembly of the 151-member Vienna-based United Nations body, the US representative urged Iran to meet its international obligations. "Otherwise it is clear that there is a broad and growing international consensus that will hold Iran accountable if it continues its defiance," US Energy Secretary Steven Chu said.
The United States remained committed to pursuing a diplomatic solution but Iran must assure the rest of the world of the peaceful nature of its nuclear intentions, Chu said. Salehi criticised the IAEA's latest report on Iran's nuclear work as unfair and suggested Western powers had influenced it. "It appears that the agency is suffering from (a) moral authority and credibility crisis," Salehi said.
The report showed Iran escalating nuclear fuel enrichment work, which it says is for peaceful uses only, in defiance of tougher UN, US and European sanctions introduced since June. It also voiced frustration over Iran's lack of full co-operation with IAEA inspectors and investigators. Relations between Iran and the IAEA have deteriorated since Yukiya Amano took over as head of the agency in December. Amano, a Japanese diplomat, has said Iran's repeated rejections of his staff was hampering the IAEA's work and Western powers have accused Tehran of intimidating the agency.
Salehi also called on major powers to resume talks "without further delay" on a plan to provide nuclear fuel to a Tehran medical reactor in exchange for some of its low-enriched uranium stockpile - potential bomb material if refined to a high level.
Western diplomats do not rule out a resumption of the nuclear fuel discussions. But they stress the need for broader negotiations which they hope will lead to Iran suspending uranium enrichment, something it has repeatedly ruled out. In its statement at the IAEA assembly, the European Union urged Iran to meet with major powers "with the ultimate goal of establishing a comprehensive relationship, involving co-operation in all fields ... and benefiting both sides." In Washington on Monday, a US Treasury official said Iran was struggling with international sanctions and pressure on its economy and banking sector was mounting.
