Small, strangely airy land (5)
I believe the answer is:
syria
'land' is the definition.
(I know that Syria is a Asian country)
'small strangely airy' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'strangely' is an anagram indicator.
'airy' with letters rearranged gives 'yria'.
's'+'yria'='SYRIA'
(Other definitions for syria that I've seen before include "Country bordering Lebanon" , "Antioch once its capital" , "Middle-East Republic" , "Middle-Eastern country" , "Middle Eastern country" .)
