Brussels, 25/07/2005 (Agence Europe) - Pending the package of “concrete proposals” for technological, commercial and political cooperation that the EU-3 (Germany, France and the United Kingdom) is to hand over to Teheran early August, Iran continues to blow hot and cold on the difficult negotiations over the nuclear issue. On one hand, it seeks to reassure Europeans who are concerned that the Iranian side will get “tougher” when the new Iranian president, Mahmoud Ahmadinejad, takes over on 3 August, and, on the other, it reasserts its firm intention to respect the “right of Iran” to rein in the nuclear combustion cycle for its purposes. Last Saturday, the spokesperson for the Ministry of Foreign Affairs, Hamid Reza Assefi, gave his assurance that “Iran's attitude over the nuclear issue and its strategic objectives will not change with the new government that will follow the same political line”. The EU-3 is nonetheless warned. During the meeting of the steering committee for talks last Wednesday (EUROPE 8996), Iranians set out the minimum acceptable to Teheran to prevent negotiations from entering an impasse, Mr Assefi explained, before adding: “The concrete proposals from Europeans will not be acceptable unless they recognise Iran's right to enrich uranium and we shall not wait very long before going on to other decisions”. On Sunday evening, the warning launched by the outgoing Iranian President, Mohammad Khatami, was still clearer: “Iran will shortly resume some of its ultra-sensitive nuclear activities whatever the EU offers it in exchange to dissuade it from doing so”, he told the Irna agency. “We have suspended work for two months in Ispahan (where the uranium conversion plants are located), the time it takes for the EU to present new concrete proposals. This will not of course be extended”, he continued. On Saturday, the chief negotiator on the nuclear issue, Hassan Rohani, revealed that Iran owned a “considerable number” of centrifugal systems “already manufactured and ready to function”. According to the experts, only one thousand centrifugal systems are required to enrich uranium at a military level.
