"As long as we know, the Syrian government and Mr. Bashar Assad still have the necessary power and might in Damascus and other cities," Araqchi told FNA on Saturday.
He referred to the complex situation of Syria, and said, "We don't think any change can be made in any country through the dispatch of arms, weapons and terrorists from outside the country."
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.
Hundreds of people, including members of the security forces, have been killed, when some protest rallies turned into armed clashes.
The government blames outlaws, saboteurs, and armed terrorist groups for the deaths, stressing that the unrest is being orchestrated from abroad.
In October 2011, calm was eventually restored in the Arab state after President Assad started a reform initiative in the country, but Israel, the US and its Arab allies are seeking hard to bring the country into chaos through any possible means. Tel Aviv, Washington and some Arab capitals have been staging various plots in the hope of increasing unrests in Syria.
