Where kips are spent (4)
I believe the answer is:
laos
'where kips are spent' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for laos that I've seen before include "Republic of southeast Asia" , "Country of Indo-China, capital Vientiane" , "Republic in southeastern Asia" , "South-east Asian republic, capital Vientiane" , "part of Asia" .)
