Mango oil produced in the country (8)
I believe the answer is:
mongolia
'the country' is the definition.
(Mongolia is an example)
'mango oil produced' is the wordplay.
'produced' indicates an anagram.
'mango'+'oil'='mangooil'
'mangooil' anagrammed gives 'MONGOLIA'.
'in' acts as a link.
(Other definitions for mongolia that I've seen before include "Log Naomi into the vast Asian region" , "Eastern state" , "Republic of east central Asia" , "Country between China/Russia" , "Asian country" .)
