Turkish President Recep Tayyip Erdogan described his trip to the Gulf to deal with the Qatar crisis as "productive and successful".
"The visits on the Gulf tour were productive and successful," Erdogan told lawmakers from his ruling AK Party at a parliamentary meeting.
"The contacts we have made during this visit have been useful, and we will continue our efforts for the stability and peace of the region with increasing determination," Reuters cited him as saying.
Erdogan left Qatar on July 25 after two days in the Gulf trying to mediate in the worst row among Arab states for years but there was no sign he had made any progress.
