According to the resolution, Iran must comply within 60 days, i.e. before 20 February 2007. Iran has strongly rejected this resolution. Iran's parliament passed a bill on 27 December 2006 obliging the government to "revise" its cooperation with the International Atomic Energy Agency and to accelerate its drive to master nuclear technology in a reaction to the U.N. resolution. The bill gave President Mahmoud Ahmadinejad's government a free hand to adopt a tougher line against the IAEA, including ending its inspections of Iran's atomic facilities. On March 2, 2007, six key nations, including the 5 permanent members of the UN Security Council, which hold veto power, have agreed to pass a new resolution to impose tougher sanctions on Iran regarding its nuclear issue at the United Nations Security Council, French Foreign Minister Philippe Douste-Blazy said. In March 2007, Russia announced that construction of a nuclear reactor would be delayed at least two months because Iran had failed to make monthly payments since January. It said the delay could cause "irreversible" damage to the project. Because of the delay, Russia also indefinitely put off the delivery of enriched uranium fuel it had promised to provide Iran in March. Iran, which denied falling behind in payments, was furious, convinced Russia was pressuring the country to bend to the U.N. Security Council, which has placed sanctions against it for refusing to suspend uranium enrichment. The pattern of Russia's behavior has strengthened Iran's determination to obtain the full technology to build nuclear power plants and end its dependence because they say Russia has never been and will never be a reliable partner. On February 20, 2007, before the expiration of the United Nations Security Council deadline asking Iran to suspend uraninium enrichment, Ali Larijani, Iran's Head of the National Security Council, warned that “double standards will severely damage the credibility of international bodies“. “I think certain countries are seeking adventure on Iran’s nuclear case. You know that some countries until now have not signed the NPT, but are conducting nuclear activities,“ he said, regretting that no action has been taken against such countries while the UN Security Council has passed a resolution against Iran. On March 18, 2007, Iran, under fire from Western powers over its atomic program, criticized Britain's plans to renew its nuclear arsenal as a "serious setback" to international disarmament efforts. Britain's parliament backed Prime Minister Tony Blair's plans to renew the country's Trident missile nuclear weapons system. "Britain does not have the right to question others when they're not complying with their obligations" referring to the obligation by the U.K., United States, Russia and France to disarm under the NPT accord and "It is very unfortunate that the UK, which is always calling for non-proliferation not only has not given up the weapons but has taken a serious step toward further development of nuclear weapons," Iran's envoy to the International Atomic Energy Agency, told a conference examining the Trident decision.
