Diplomats say Russia and China have scuttled a Western attempt to introduce a resolution on Iran`s nuclear defiance at a meeting of the International Atomic Energy Agency. The diplomats said the move appears to have been prompted by unhappiness about not being informed in time that such a resolution was in the making. They spoke Tuesday on condition of anonymity because their information was confidential. A Western push for an International Atomic Energy Agency resolution focused on Iran`s nuclear defiance was back on track Tuesday, diplomats said, after Russia withdrew its opposition. Russia had said Monday that it would not back new U.N. sanctions against Tehran unless Western nations at the IAEA`s board meeting gave up plans for a resolution, diplomats said. They said Moscow had been unhappy that it was not informed earlier of plans for such a resolution. The ultimatum delayed the vote in the U.N. Security Council for two hours before Russia joined the four other permanent council members and nine of the non-permanent members in voting in favor. Indonesia abstained. Diplomats accredited to the IAEA told The Associated Press on Tuesday that Russia changed its mind after being given assurances that Moscow would have a substantial say in the document originating with Britain, France and Germany. They spoke on condition of anonymity because their information was confidential. In New York, Russia`s U.N. Ambassador Vitaly Churkin told the AP after the U.N. resolution was approved that "there was a misunderstanding that was cleared." There was an agreement, he said, that "we`re working everywhere as the six on this Iranian nuclear issue," he said, referring to the six nations at the forefront of efforts to ensure Iran does not develop an atomic weapon program - the U.S., Russia, China, Britain, France and Germany. "So whatever initiatives are coming, or are discussed, or being proposed, are going to be discussed within the six. That was the bottom line of this whole discussion," he said. He stressed that "everywhere" included the IAEA. Germany`s U.N. Ambassador Thomas Matussek said "there was a technical misunderstanding which could fortunately be very quickly cleared up." The misunderstanding was that Russia was "out of the loop," he said. "It later turned out they were in the loop." U.S. Ambassador to the U.N. Zalmay Khalilzad also called it "a misunderstanding." In comments before the controversy broke, diplomats said any Vienna resolution would be mild, so as to garner maximum support. They said it would commend IAEA chief Mohamed ElBaradei for his attempts to probe Tehran`s nuclear activities but would note that Iran had stonewalled agency requests for information on its alleged nuclear weapons experiments. Iran`s nuclear past has been a key topic at IAEA board meetings for the past five years, after revelations that the Islamic Republic had carried out nearly two decades of secret atomic work, some of it potentially linked to weapons research. Iran insists its nuclear program is peaceful and for civilian purposes. The last IAEA resolution, more than two years ago, referred Tehran`s nuclear file to the Security Council. Before Monday`s, the council had imposed two other sets of sanctions to punish Iran for its refusal to suspend uranium enrichment and fully open its nuclear activities to agency inspectors. Iran not only continues enrichment - which can produce both nuclear fuel and the fissile core of nuclear warheads - but has also expanded its activities, saying it has a right to the technology for a civilian nuclear program. Additionally fueling Western frustrations is Tehran`s refusal to discuss allegations that it tried to make nuclear weapons through projects enriching uranium, testing explosives and designing missiles and warheads suitable for a nuclear payload. While a Feb. 22 IAEA report said a probe had made progress on other past nuclear activities, it said that Tehran had not responded properly to intelligence forwarded by the U.S. and its allies purportedly showing nuclear weapons technology being developed by Iran. Iran has focused on the agency`s assessment of progress on some topics to assert that the IAEA report vindicates its claims that its nuclear project is strictly civilian. Iran`s chief delegate to the IAEA, Ali Ashgar Soltanieh, on Monday said the report "proves Iran`s activities are peaceful." But as the board meeting convened in Vienna, ElBaradei urged Iran to stop obstructing his experts on the issue of alleged weapons experiments. Calling the issue of alleged weapons development "a matter of serious concern," he asked Iran "to be as active and cooperative as possible in working with the agency" to put the issue to rest. "A full-fledged examination of this issue has yet to take place," he said in comments to the board, indirectly denying Iranian suggestions that an IAEA probe of Tehran`s past activities has ended positively.
