Arab League Secretary General Amr Moussa has called for dialogue between Iran and the Arab world to resolve all regional issues through diplomacy. "Time has come for an Arab-Iranian dialogue, which should include all issues,'' Moussa told reporters in Cairo on Tuesday. "We have differences and problems but these can be solved because Iran is an important country,'' he added. Moussa said the dialogue should be conducted through a "regional system" in the future, AP reported. He was likely referring to a recent proposal by Bahraini Foreign Minister Sheik Khalid Bin Ahmed al-Khalifa to establish a regional body that would include all Middle Eastern countries. Bahrain's top diplomat said his proposal has been submitted to the Arab League.
