Tibetan animal carries North American (4)
I believe the answer is:
yank
'american' is the definition.
(Yank can informally mean an American)
'tibetan animal carries north' is the wordplay.
'tibetan animal' becomes 'yak' (I've seen this before).
'carries' indicates putting letters inside (inserted letters carried inside).
'north' becomes 'N' (abbreviation).
'yak' placed around 'n' is 'YANK'.
(Other definitions for yank that I've seen before include "Pull sharply" , "An informal American - tug him" , "one across pond" , "Sudden hard pull" , "Pull violently - American" .)
