Saudi Arabia must host Qatar's football teams during the Asian Champions League for home fixtures next month and allow Saudi teams to travel to the neighbouring state for away matches despite the Gulf diplomatic crisis, according to the ruling of Asia's football governing body.
"Clubs from Qatar, Saudi Arabia and the United Arab Emirates should be played on a home and away basis in 2018 as per the AFC regulations," AFC said in a statement published on its website.
The statement said AFC made the decision following an independent safety and security assessment.
Saudi football teams are due to travel to Qatar for away matches beginning next month.
Saudi Arabia's Al Hilal have been placed with Qatar's Al Rayyan in Group D of the AFC Champions League beginning February 12.
Qatar's Al Sadd are in Group C along with the UAE's Al Wasl, while in Group B Qatar's Al Duhail are pitted against the UAE's Al Wahda.
