Country featured in Dublin Diaries (5)
I believe the answer is:
india
'country' is the definition.
(I know that India is an Asian nation)
'featured in dublin diaries' is the wordplay.
'featured in' indicates the answer is hidden within the clue.
'INDIA' is hidden in the letters of 'dublin diaries'.
(Other definitions for india that I've seen before include "Cricket team" , "Country of the Ganges" , "Country: I (comms.)" , "A Passage to - (E.M. Forster)" , "Republic in south Asia" .)
