In China, majority group cry for attention in Asian city (5)
I believe the answer is:
hanoi
'asian city' is the definition.
(capital of Vietnam)
'in china majority group cry for attention' is the wordplay.
'in china majority group' becomes 'han' (Chinese ethnic group).
'cry for attention' becomes 'oi' (oi!).
'han'+'oi'='HANOI'
'in' is the link.
(Other definitions for hanoi that I've seen before include "Asian capital on the Red River" , "Vietnamese city" , "Capital city of Vietnam" , "Asian city" , "foreign city" .)
