Links from China with a promotion (5)
I believe the answer is:
chain
'links' is the definition.
(a chain is made up of links)
'china with a promotion' is the wordplay.
'china' anagrams to 'CHAIN'.
However, I am not clear how this is indicated.
'from' is the link.
(Other definitions for chain that I've seen before include "Group of atoms" , "Series of links; sixty six feet" , "Part of cycle" , "Line of links" , "Twenty-two yards" .)
