China ends Red revolution (7)
I believe the answer is:
dresden
'china' is the definition.
(a type of porcelain)
'ends red revolution' is the wordplay.
'revolution' indicates an anagram.
'ends'+'red'='endsred'
'endsred' is an anagram of 'DRESDEN'.
(Other definitions for dresden that I've seen before include "Fine china named after German city" , "Famous china made at Meissen" , "Industrial city" , "Germany city - reddens (anag)" , "SE German city" .)
