Country involved in machinations (5)
I believe the answer is:
china
'country' is the definition.
(China is an example)
'involved in machinations' is the wordplay.
'involved in' indicates a hidden word.
'CHINA' is hidden within 'machinations'.
(Other definitions for china that I've seen before include "It's fragile, though its economy is not!" , "Londoner's friend" , "High quality porcelain" , "Household ceramics" , "The most populous country in the world" .)
