S. Samuel C. Rajiv replies: The initial diplomatic efforts on the Iranian nuclear issue were spearheaded by the United Kingdom, France and Germany (E3). Some of the few instances of successful engagement were the Tehran Agreed Statement of October 2003 and the Paris Agreement of November 2004 that Iran entered into with the E3. The E3 engagement process, however, hit a roadblock in the light of Iran’s decision of August 01, 2005 to resume uranium conversion activities at Isfahan.

The P5+1/E3+3 (made up of five permanent members of the UNSC along with Germany) took forward the process of engagement spearheaded by E3 countries after the Iranian nuclear issue was referred to the UNSC by the IAEA in February 2006. Germany’s involvement therefore began as part of the E3 as early as in 2003 and continued when the negotiation process was expanded to include the other three permanent members of the UNSC in 2006. 

Brazil meanwhile was involved in such efforts as the May 2010 Brazil-Turkey-Iran nuclear swap deal under the terms of which (similar to the October 2009 deal involving Russia and France) Iran was to have transferred 1200 kgs of low enriched uranium (LEU) to Turkey, in return for 120 kgs of uranium fuel rods from the Vienna Group (US, Russia, France, and the IAEA) within a year of depositing the LEU. The US and France, however, rejected the deal given that Iran’s stockpile of LEU had doubled since October 2009. Such efforts also raised the stakes in the US–Turkey/Brazil bilateral ties, with these countries’ foreign policy efforts seemingly at odds with the US interests and preferences.
