TEHRAN  - President Mahmoud Ahmadinejad on Monday bluntly rejected as "repetitive" calls for Iran to suspend uranium enrichment, as world powers reviewed its response to an offer to end the five-year nuclear crisis. Ahmadinejad's defiant remarks were the latest sign Tehran's response contains no suggestion it is ready to suspend uranium enrichment activities, which world powers fear could be used to make a nuclear weapon. "It is a repetitive scenario," the state news agency IRNA quoted Ahmadinejad as saying in an interview with Malaysian television from Kuala Lumpur where he is to attend the summit of the D8 group of developing nations. "On one side they (world powers) ask to negotiate and on the other they threaten and say that we must give in to their illegal demands and renounce our rights," he added. His comments come days after Iran gave an undisclosed response to the package from six world powers to break the deadlock in the nuclear standoff, which has raised fears of regional conflict and sent oil prices spiralling. The proposal from the world powers offers Iran technological incentives in exchange for suspending uranium enrichment, which the West fears could be used to make a nuclear weapon. "We are in favour of dialogue but we will negotiate in a just atmosphere and on common subjects because negotiations in an unbalanced climate will have no result," Ahmadinejad said. Meanwhile, EU foreign policy chief Javier Solana on Monday said he was not too optimistic about prospects for a breakthrough with Iran on its suspect nuclear programme, saying: "It's difficult." Solana said he hoped to meet soon with Iran's chief nuclear negotiator after Tehran on Friday delivered its response to an international offer to halt uranium enrichment, which the West fears could be used to make nuclear weapons. "I hope that we will be able to continue the dialogue in the coming weeks.... We'll see, but I don't want to give the impression of being too optimistic," Solana told reporters on the sidelines of an EU-NATO meeting in Paris. "It's difficult," he said, describing the response from Tehran as a "complicated and difficult letter that must be thoroughly analysed." Asked when he planned to meet with top Iranian nuclear negotiator Saeed Jalili, Solana said "I hope before the end of the month." He added that world powers were still in talks about Iran's response to the package presented by permanent UN Security Council members Britain, China, France, Russia and the United States plus Germany. French Foreign Minister Bernard Kouchner said he had read an "outline" of the response and that he did not hold out much hope of a breakthrough. "I don't think that it provides great hope. But it gives a little bit of hope," Kouchner said. Russia appeared to turn up the pressure on Tehran, with President Dmitry Medvedev's diplomatic advisor saying that Moscow expected Iran to reciprocate to the latest offer. "Russia will do everything to stimulate dialogue with Iran and expects corresponding signals from the leaders of Iran," said Sergei Prikhodko in Japan where Group of Eight leaders were meeting. The United States said it was consulting its partners. "We'll just have to see how that is received by others before we make a formal response," said White House spokeswoman Dana Perino.
