Confine in NE China perhaps (7)
I believe the answer is:
enchain
'confine' is the definition.
(I know that enchain is a kind of confine)
'ne china perhaps' is the wordplay.
'perhaps' is an anagram indicator.
'ne'+'china'='nechina'
'nechina' anagrammed gives 'ENCHAIN'.
'in' is the link.
(Other definitions for enchain that I've seen before include "Put in fetters" , "Immobilise" , "Hold captive" , "Bind" , "Hold fast" .)
