TEHRAN (Reuters) - Major powers will only achieve results in their meetings on Iran if they adopt a realistic approach and recognise its nuclear rights, the Islamic Republics Foreign Ministry spokesman said on Sunday. Ramin Mehmanparast made the comment a day after the six powers met to discuss prospects of further sanctions against Iran over its nuclear programme, with participants saying China made clear it opposed more punitive action at the moment. Irans official IRNA news agency said Mehmanparast described the powers failure to reach an agreement on Irans nuclear issue as natural. Diplomats from the United States, Britain, France, Germany, Russia and China held a three-hour meeting in New York on Saturday. It came after Iran ignored US President Barack Obamas Dec 31, 2009, deadline to respond to an offer from the six powers of economic and political incentives in exchange for halting its nuclear enrichment activities. The solution lies in the recognition of Irans nuclear rights by the group, Mehmanparast said. The planned meetings of the (six powers) would not have clear results as long as they lack a realistic approach. Washington and its Western allies accuse Iran of trying to develop nuclear weapons under the cover of its civilian atomic programme. Iran, the worlds fifth-largest crude exporter, says its programme is designed to generate electricity. The European Union, which hosted the meeting at its New York office, said that despite the lack of a concrete outcome, further sanctions were now on the big-power agenda and the six would be in contact again soon to continue the discussions. All the powers except China sent top-level Foreign Ministry officials to Saturdays meeting. But Beijing, which said earlier this month that it was not the right time for new sanctions, sent only a mid-ranking diplomat from its UN mission.
