Lands on the Persian Gulf (8)
I believe the answer is:
'lands on the persian gulf' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for emirates that I've seen before include "Federation of Arab states" , "Abu Dhabi and Dubai, say" , "ie Master (anag.)" , "in the airline business" , "Arab lands" .)
