Stall China’s foreign correspondent? (3,3)
I believe the answer is:
pen pal
'foreign correspondent?' is the definition.
(a pen pal might be from another country)
'stall china's' is the wordplay.
'stall' becomes 'pen' (both can mean an enclosure for animals).
'china' becomes 'pal' (china plate is Cockney rhyming slang for mate).
'pen'+'pal'='PEN-PAL'
(Other definitions for pen pal that I've seen before include "Mail friend" , "Friend who communicates in letters" , "Friend who communicates in writing" , "foreign correspondent" , "friendly writer" .)
