Bin Farhan was last in Damascus in April 2023 to meet former President Bashar al-Assad, Reuters reported.
The following month, Saudi Arabia invited Assad to an Arab League summit in Riyadh, a body that had suspended Syria's membership over his crackdown on protesters in 2011.
Arab countries have historically been concerned about Syria's production and trade of captagon, an amphetamine-like drug used in the Persian Gulf by party-goers and laborers alike.
Syria is under a caretaker administration after rebels overthrew Assad in December 2024.
