China: a little souvenir, a miniature turned up (5)
I believe the answer is:
imari
'china' is the definition.
(type of porcelain)
'a little souvenir a miniature turned up' is the wordplay.
'a little' says the answer is hidden in the clue.
'turned up' says the letters should be written in reverse.
'irami' is hidden in the letters of 'souvenir a miniature'.
'irami' backwards is 'IMARI'.
(Other definitions for imari that I've seen before include "decorative porcelain" , "sort of porcelain" , "decorative ware" , "Japanese earthenware" , "Type of rich Japanese porcelain" .)
