Nuclear program of Iran
U.S. President Obama reportedly sent a letter dated 20 April 2010 to President Lula of Brazil, in which he outlined a proposal of fuel swap. While expressing skepticism that the Iranians would now be willing to accept such a deal, having provided "no credible explanation" for the previous deal's rejection, President Obama wrote "For us, Iran’s agreement to transfer 1,200 kg of Iran’s low enriched uranium (LEU) out of the country would build confidence and reduce regional tensions by substantially reducing Iran’s LEU stockpile." Turkish Prime Minister Recep Tayyip Erdogan received a similar letter. A senior U.S. official told the "Washington Post" that the letter was a response to Iran's desire to ship out its uranium piecemeal, rather than in a single batch, and that during "multiple conversations" U.S. officials made clear that Iran should also cease 20% enrichment; however, the official stated "there was no president-to-president letter laying out those broader concerns".
Egypt–Iran relations
Following the Egyptian Revolution of 2011, and the appointment of ambassadors after nearly 30 years, Egyptian President Mohammed Morsi made a historic first visit to Iran since the Iranian Revolution for the 2012 Non-Aligned Movement summit on 30 August, where it handed over the rotating presidency to Iran. Iranian president, Mahmoud Ahmadinejad also visited Egypt in February 2013, making him the first Iranian president to travel to Egypt since the Iranian Revolution.
