On Tuesday, they named Mohammed al-Bashir, who headed the rebels' self-proclaimed "Salvation Government" in their northwestern bastion of Idlib, as the country's transitional prime minister until March 1.
Arnaout said a meeting would be held on Tuesday "between Salvation Government ministers and the former ministers" of Assad's administration to carry out the transfer of power.
"This transitional period will last three months," he added in an interview with AFP. "Our priority is to preserve and protect institutions."
Speaking at the state television headquarters, Arnaout pledged that they would institute "the rule of law".
"All those who committed crimes against the Syrian people will be judged in accordance with the law," he added.
Asked about religious and personal freedoms, he said "We respect religious and cultural diversity in Syria", adding that they would remain unchanged.
