Land - a sign of being bunged up, say (5)
I believe the answer is:
qatar
'land' is the definition.
(I know that Qatar is a Asian country)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for qatar that I've seen before include "Gulf sheikhdom" , "who won the cup in 2010?" , "State in the Persian Gulf" , "Tiny gulf state" , "Arab country" .)
