facility. This "six months" clause was standard for implementation of all IAEA safeguards agreements until 1992, when the IAEA Board of Governors decided that facilities should be reported during the planning phase, even before construction began. Iran was the last country to accept that decision, and only did so on 26 February 2003, after the IAEA investigation began. In May 2003, shortly after the US invasion of Iraq, elements of the government of Mohammad Khatami made a confidential proposal for a "Grand Bargain" through Swiss diplomatic channels. It offered full transparency of Iran's nuclear program and withdrawal of support for Hamas and Hezbollah, in exchange for security assurances from the United States and a normalization of diplomatic relations. The Bush administration did not respond to the proposal, as senior US officials doubted its authenticity. The proposal reportedly was widely blessed by the Iranian government, including Supreme Leader Ayatollah Khamenei. France, Germany and the United Kingdom (the EU-3) undertook a diplomatic initiative with Iran to resolve questions about its nuclear program. On 21 October 2003, in Tehran, the Iranian government and EU-3 Foreign Ministers issued a statement known as the Tehran Declaration in which Iran agreed to co-operate with the IAEA, to sign and implement an Additional Protocol as a voluntary, confidence-building measure, and to suspend its enrichment and reprocessing activities during the course of the negotiations. The EU-3 in return explicitly agreed to recognize Iran's nuclear rights and to discuss ways Iran could provide "satisfactory assurances" regarding its nuclear power program, after which Iran would gain easier access to modern technology. Iran signed an Additional Protocol on 18 December 2003, and agreed to act as if the protocol were in force, making the required reports to the IAEA and allowing the required access by IAEA inspectors, pending Iran's ratification of the Additional Protocol. The IAEA reported 10 November 2003, that "it is clear that Iran has failed in a number of instances over an extended period of time to meet its obligations under its Safeguards Agreement with respect to the reporting of nuclear material and its processing and use, as well as the declaration of facilities where such material has been processed and stored." Iran was obligated to inform the IAEA of its importation of uranium from China and subsequent use of that material in uranium conversion and enrichment activities. It was also obligated to report experiments with the separation
