Iranian President Mahmoud Ahmadinejad vowed on Friday that the country would pursue its nuclear programme until it could mass-produce atomic fuel, and branded those trying to stop it as “bullies”. “Tehran intends to continue our activity until we manage industrial-scale production of nuclear fuel for our atomic power stations,” said Ahmadinejad, according to a text of his speech at a regional summit here. He stressed Iran’s desire to work within international law and under the scrutiny of the UN’s watchdog International Atomic Energy Agency (IAEA).Meanwhile, US Ambassador to the UN John Bolton on Friday challenged Russia and China to come up with legal alternatives to break the impasse on a draft UN resolution ordering Iran to suspend its nuclear programme. Russia and China object to the use of Chapter VII of the UN Charter, usually invoked by the UN Security Council for peacekeeping missions and other legally binding actions. That provision also allows for sanctions and even war but a separate resolution is required to specify either step. “One of the issues we are discussing is what constitutes a mandatory resolution, whether Security Council resolutions that are not under Chapter VII are mandatory or not,” Bolton said. “The issue whether there is another way that is acceptable is something that we have asked the Russians and the Chinese to provide. We are waiting to hear how one might do that,” he said.
