"Dialogue among regional countries, Syria in particular, can prevent the meddling by trans-regional countries," Mehman-Parast said on Saturday.
He noted that consultations and cooperation among countries of the Middle East can be the best way to overcome the regional crises.
In similar remarks earlier this week, Iranian Vice-President for Parliamentary Affairs Lotfollah Forouzandeh stressed the necessity for finding a political solution to the current crisis in Syria.
"The Islamic Republic is against any foreign interference in Syria's internal affairs, and believes that the ongoing crisis in the Muslim country should be resolved through national Syrian-Syrian dialogue," Forouzandeh said on Friday.
He noted that a halt to the crisis in Syria will benefit the regional countries.
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.
The US and its western and regional allies have long sought to topple Syrian President Bashar al-Assad and his ruling system. Media reports said that the Syrian rebels and terrorist groups have received significantly more and better weapons in recent weeks, a crime paid for by the Persian Gulf Arab states and coordinated by the United States.
The US daily, Washington Post, reported in May that the Syrian rebels and terrorist groups battling Assad's government have received significantly more and better weapons in recent weeks, a crime paid for by the Persian Gulf Arab states and coordinated by the United States.
The newspaper, quoting opposition activists and US and foreign officials, reported that Obama administration officials emphasized the administration has expanded contacts with opposition military forces to provide the Persian Gulf nations with assessments of rebel credibility and command-and-control infrastructure.
Opposition activists who several months ago said the rebels were running out of ammunition said in May that the flow of weapons - most bought on the black market in neighboring countries or from elements of the Syrian military in the past - has significantly increased after a decision by Saudi Arabia, Qatar and other Persian Gulf states to provide millions of dollars in funding each month.
