Salehi said on Wednesday that several countries and Syrian groups will attend the meeting.
On Monday, Salehi warned that any attempt to disintegrate Syria or to cause a potential power vacuum in the Arab country would affect the entire region.
“The Islamic Republic supports Syria’s integrity, unity and sovereignty, and everyone should do the same,” said Salehi.
The Iranian foreign minister said the Syrian government and the opposition should engage in dialog to reach a political solution to the crisis in Syria.
Salehi reiterated that Iran was against foreign interference in the internal affairs of Syria, adding that the Syrian people should determine the destiny of their country.
The Iranian top diplomat further expressed optimism on “the convergence of views between the United States and Russia” on finding a peaceful resolution to the crisis in Syria.
At a joint press conference in Moscow on May 7, Russian Foreign Minister Sergei Lavrov and US Secretary of State John Kerry agreed to encourage the Syrian government and the foreign-backed militants to politically resolve the crisis. The ‘peace conference’ on Syria will serve as a follow-up to an earlier Geneva meeting, which was held in June 2012.
Turmoil has gripped Syria for over two years, and many people, including large numbers of Syrian soldiers and security personnel, have been killed in the foreign-sponsored militancy.
