Country landscape Russia provides (4)
I believe the answer is:
peru
'country' is the definition.
(Peru is an example)
'landscape russia provides' is the wordplay.
'provides' indicates the answer is hidden within the clue.
'PERU' is hidden within 'landscape russia'.
(Other definitions for peru that I've seen before include "Machu Picchu country" , "Andes republic" , "Lima's country" , "S American country, capital Lima" , "South American country" .)
