The station said in a news flash that Yusuf bin Alawi had met with Assad, as reported by Reuters.
The state news agency SANA said they had met in Damascus, and published a photo of the two men shaking hands.
Oman sees itself as a conciliator in a volatile region and has a history of constructive relations with Syria's close ally Iran. Syria's foreign minister traveled to Oman to meet Alawi in August.
