Salehi said that originally, Egyptian President Mohammad Mursi had suggested a gathering of four countries, but Iran's President Mahmoud Ahmadinejad suggested that two more countries be added in this group.
"Originally it was proposed that the foreign ministers of the six countries should meet in Egypt, but then, for various reasons, it was decided that experts from the six countries should take part in the first gathering in Cairo, Egypt," Iranian foreign minister said.
"Following this, experts from six countries gathered in Cairo Egypt on Monday to discuss the situation in Syria, and find a way to end the violence in the Arab country," he added.
Syria has been experiencing unrest since March 2011 with organized attacks by well-armed gangs against Syrian police forces and border guards being reported across the country.
Given the importance of ending Syrian crisis in the peace and security of Middle East as well as whole world, an initiative for forming the quadrilateral contact group on Syria was put forward by Egypt's first post-revolution President Mohammad Mursi at a recent emergency meeting of the Organization of Islamic Cooperation (OIC) in Mecca, Saudi Arabia.
The proposal went under further discussions during a recent phone talk between the Iranian and Egyptian foreign ministers and was also a topic of discussions between senior Iranian and Egyptian officials on the sidelines of the 16th heads-of-state summit meeting of the Non-Aligned Movement (NAM) in Tehran late in August.
