The Arab League on Wednesday welcomed the appointment of an interim prime minister by the Syrian opposition, calling it a sign of unity, dpa reported.
"The Arab League resolutions have long called on the Syrian opposition forces to unify their efforts and forge a common political consensus," said the head of the pan-Arab grouping Nabil al-Arabi.
"The latest development marks a step in this direction."
The opposition on Monday named Syrian businessman Ghassan Hitto as the man to head a government as part of its efforts to consolidate the rebellion against President Bashar al-Assad.
The provisional government will be tasked with administering areas freed during the two-year civil war.
An Arab League summit, due to be held in Qatar on March 26-27, is expected to give Damascus' seat to the opposition.
Syria was suspended from the 22-member organization in November 2011 over the government's violent crackdown on anti-regime rebels.
