Iran has always reiterated since the beginning of unrests in Syria that the Muslim country's crisis does not have a military solution and the only solution is a comprehensive political agreement," Dehqani said, addressing the UN General Assembly's meeting on Friday.
He also underlined that the UN plays an important role in settling the Syrian crisis, and said, "The UN officials should help in finding a political solution to the crisis while maintaining their impartiality."
"Iran's efforts have taken place on the basis of cooperation with the Syrian government, the opposition political groups and UN officials and the latest example to such was trilateral meeting between Iran, Syria and Switzerland in 2013 with the aim of dealing with Syria's conditions from humanitarian perspective," he added.
On Wednesday, the "Friends of Syria Conference" was inaugurated in Tehran to discuss the latest developments in crisis-hit Syria and find diplomatic solutions to the ongoing bloodshed in there.
The gathering started work in the presence of heads of parliamentary foreign policy commissions of Iran, Algiers, Iraq, Syria, Lebanon and Russia reviewed ways to cease bloodshed and violation of human rights in Syria.
Resolutions of the Syrian crisis through diplomacy and immediate end to violation of human rights were the main topics of the gathering.
Venezuelan and Cuban ambassadors to Tehran were also present in the event.
Last Saturday, Former Secretary-General of the Arab League Amr Moussa underlined that the only way out of the Syrian crisis is inviting Iran to take part in peace negotiations which have not been successful during the last two meetings in Geneva.
Speaking in an interview with the As-Safir of Lebanon, the veteran Egyptian diplomat said the three countries of Iran, Egypt, and Saudi Arabia should be part of any political solution to the ongoing crisis in Syria.
Noting that big powers acted incorrectly at the beginning of the Syrian crisis, Moussa said bullying powers led by a number of western countries are usually well in triggering and fueling conflicts but fail to resolve tensions.
He said during the past two Geneva conferences, the world has witnessed the inefficiency of big powers in finding a solution to the situation in Syria.
The Veteran Egyptian diplomat noted that the Syrian crisis had many negative impacts on the entire region, its neighboring countries in particular, including the spread of terrorism and destruction as well as insecurity, unrest and chaos.
Earlier this month, Iranian Deputy Foreign Minister Hossein Amir Abdollahian once again reiterated that Iran’s presence in the International Geneva II Peace Conference on Syria will be necessary, but Tehran would not accept any precondition in this regard.
“Iran is ready to participate in the next round of talks in the Swiss city of Geneva on the ongoing Syrian crisis only if it is invited to the event without any preconditions,” Amir Abdollahian told reporters.
He underlined that the US and other parties should be realistic in order for the Geneva talks to yield results.
“Iran has always stressed the need for dialogue and diplomacy as the only solution to the Syrian conflict,” Amir Abdollahian said.
Iranian officials have repeatedly underlined that Tehran is in favor of negotiations between the Syrian government and opposition groups to create stability in the Middle Eastern country.
In November 2012, Iran hosted a meeting between the representatives of the Syrian government and opposition to encourage them to start talks to find a political solution to their problems. The National Dialogue Conference kicked off work in Tehran mid November with the motto of 'No to Violence, Yes to Democracy".
The meeting brought together almost 200 representatives of various Syrian ethnicities, political groups, minorities, the opposition, and state officials.
Syria has been the scene of deadly violence since March 2011. Over 130,000 people have reportedly been killed and millions displaced due to the crisis.
According to reports, the western powers and their regional allies -- especially Qatar, Saudi Arabia, and Turkey -- are supporting the militants operating inside Syria.
