Host city of the 2008 Olympics (7)
I believe the answer is:
beijing
'host city of the 2008 olympics' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for beijing that I've seen before include "Eastern city" , "Forbidden City location" , "Chinese capital" , "2008 Olympics host" , "Capital of China" .)
