Iran's chief nuclear negotiator Saeed Jalili has agreed to resume talks with the Iran Six on its controversial nuclear program after November 10, EU High Representative for Foreign Affairs Catherine Ashton said. The Iran Six (Russia, the United States, China, Britain, France and Germany) has been trying since 2003 to convince Iran to stop its uranium enrichment program and to alleviate concerns about its nuclear ambitions. Talks between Tehran and the Iran Six ground to a halt in 2009, after an International Atomic Energy Agency (IAEA) resolution condemned the Islamic Republic over the construction of a second uranium enrichment facility. The UN Security Council imposed a fourth round of sanctions on Iran over its nuclear program in June. Western powers suspect Iran of building nuclear weapons under the guise of a nuclear program that Tehran claims is entirely peaceful and focused on power generation.
