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".
Iran–Venezuela relations
A special election was held on 14 April 2013 to elect a new president, and Nicolas Maduro won with 50.62% of the votes, and was inaugurated on 19 April. On April 19, 2013, Ahmadinejad has arrived in Caracas to take part in Maduro’s inauguration ceremony, stating “Venezuela is on the eve of a glorious way and has an important historic mission. The Venezuelan nation should at first progress rapidly to make a prosperous, advanced, rich, and powerful country. Secondly, it should keep the flag of justice and freedom raised in Latin America… [Iran’s] relation with Venezuela…symbolizes Iran’s relation with Latin America.” Hassan Rouhani was elected as President of Iran on 15 June 2013.
