Asian country backing delay, India (7)
I believe the answer is:
kuwaiti
'asian' is the definition.
(I know that Kuwaiti is a type of asian)
'country backing delay india' is the wordplay.
'country' becomes 'UK' (United Kingdom).
'backing' shows that the letters should be reversed in order.
'delay' becomes 'wait' (synonyms).
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'uk' in reverse letter order is 'ku'.
'ku'+'wait'+'i'='KUWAITI'
(Other definitions for kuwaiti that I've seen before include "Gulf state citizen" , "Native of a Gulf state" , "Arab" , "From an Eastern Arabian country" .)
