China tea (4)
I believe the answer is:
mate
I believe this is a double definition.
'china' is the first definition.
(china plate is Cockney rhyming slang for mate)
'tea' is the second definition.
(South American hot drink)
(Other definitions for mate that I've seen before include "Chess finale" , "Perhaps the wife" , "Team (anag.)" , "Spouse on team" , "Finish game" .)
