North-eastern China's mountainous region (5)

Ross

I believe the answer is:

nepal

'mountainous region' is the definition.
(mountainous country in Asia)

'north-eastern china's' is the wordplay.
'north eastern' becomes 'NE' (abbreviation).
'china' becomes 'pal' (china plate is Cockney rhyming slang for mate).
'ne'+'pal'='NEPAL'

(Other definitions for nepal that I've seen before include "somewhere in the Himalayas" , "mountainous area" , "Hindu kingdom in south Asia" , "Country in plane north-west of India" , "World's only Hindu kingdom" .)

I've seen this clue in The Telegraph.
