Small country's boast whole continent listened to (7)

I believe the answer is:

croatia

'small country's' is the definition.

I don't understand how the rest of the clue works.

(Other definitions for croatia that I've seen before include "Adriatic country" , "Balkan state, became independent in 1991" , "Adriatic nation" , "Republic in SE Europe, capital Zagreb" , "Country of S. Europe" .)

I've seen this clue in The Guardian.
