Gadget from China accidentally imported by me (7)
I believe the answer is:
machine
'gadget' is the definition.
(thesaurus)
'china accidentally imported by me' is the wordplay.
'accidentally' indicates an anagram (a chaotic or accidental ordering of the letters).
'imported by' is an insertion indicator.
'china' anagrammed gives 'achin'.
'achin' placed inside 'me' is 'MACHINE'.
'from' is the link.
(Other definitions for machine that I've seen before include "Mechanical contrivance; engine" , "Contraption" , "Industrial worker" , "Well-organised and powerful group" , "Automaton" .)
