Country promoted circuit dash (5)
I believe the answer is:
nepal
'country' is the definition.
(I know that Nepal is Asian country)
'promoted circuit dash' is the wordplay.
'promoted' says the letters should be written in reverse (going up, in a down clue).
'circuit' becomes 'lap' (synonyms).
'dash' becomes 'en' (an en dash is a dash as wide as a letter 'n').
'lap'+'en'='lapen'
'lapen' backwards is 'NEPAL'.
(Other definitions for nepal that I've seen before include "Himalayan state" , "former kingdom" , "Gurkha homeland" , "Mountainous country" , "Himalayan country" .)
