Longing to tour Middle East country (5)
I believe the answer is:
yemen
'country' is the definition.
(Yemen is an example)
'longing to tour middle east' is the wordplay.
'longing' becomes 'yen' (yen can mean a desire or longing for something).
'to tour' is an insertion indicator (to tour can mean to go around).
'middle east' becomes 'me' (abbreviation for Middle East).
'yen' placed around 'me' is 'YEMEN'.
(Other definitions for yemen that I've seen before include "Country between the Red Sea and the Gulf of Aden" , "Middle Eastern country" , "Middle East country" , "Enemy (anag) - country of Arabia" , "Arabian republic, capital Sanaa" .)
