Iran and the five permanent member nations of the United Nations Security Council plus Germany (P5-plus-1) held talks in Istanbul on April 14 and agreed that they would start full talks from May 23 in Baghdad over the issue of Iran's nuclear program.
Although the Istanbul meeting did not produce immediate results, it is hoped that it will have the effect of kick-starting the process of building mutual trust between Iran and the Western powers.
The last meeting between Iran and the six powers was held in January 2011, followed by 15 months of a diplomatic vacuum. In the meantime, Iran pushed its nuclear program and Israel started talking about possible strikes against Iran's nuclear facilities.
