Iran’s president said Wednesday that his country wants to discuss cooperation to resolve global issues and to promote peace and security at nuclear talks with world powers, but won’t talk about what it insists is its right to continue nuclear activities.

President Mahmoud Ahmadinejad spoke a day after Iran offered to resume nuclear talks this month with six nations — the United States, Russia, China, Britain, France and Germany. The talks collapsed last year and Ahmadinejad’s comments raise further questions about whether Iran is willing to reopen the dialogue on its nuclear program…

The president’s remarks were among the many conflicting and ambiguous messages from Iran over the years about its willingness to enter into nuclear negotiations. It has also sent counterproposals and used delaying tactics that have brought talks to an impasse.
