Bantu travelling across hot country (6)
I believe the answer is:
bhutan
'country' is the definition.
(I know that Bhutan is a country)
'bantu travelling across hot' is the wordplay.
'travelling' indicates anagramming the letters.
'across' is an insertion indicator.
'hot' becomes 'h' (abbreviation eg on taps).
'bantu' is an anagram of 'butan'.
'butan' enclosing 'h' is 'BHUTAN'.
(Other definitions for bhutan that I've seen before include "Bowman" , "Country of the Himalayas" , "Kingdom in Central Asia" , "Indian protectorate in the southeast Himalayas" , "kingdom near China" .)
