Feature on area in Asian country (5)
I believe the answer is:
china
'asian country' is the definition.
(China is an example)
'feature on area' is the wordplay.
'feature' becomes 'chin' (chin is a kind of feature).
'on' says to put letters next to each other.
'area' becomes 'a' (maths abbreviation).
'chin'+'a'='CHINA'
'in' is the link.
(Other definitions for china that I've seen before include "Asian country" , "communist state" , "country out east" , "Tableware; country" , "What's tea" .)
