Latin American power in China is extraordinary (8)
I believe the answer is:
hispanic
'latin american' is the definition.
(I've seen this in another clue)
'power in china is extraordinary' is the wordplay.
'power' becomes 'p' (symbol in physics).
'in' is an insertion indicator.
'extraordinary' indicates an anagram.
'china'+'is'='chinais'
'chinais' anagrammed gives 'hisanic'.
'p' inserted within 'hisanic' is 'HISPANIC'.
(Other definitions for hispanic that I've seen before include "Spanish-speaking American" , "Relating to Spain" , "Of Spain and Spanish-speaking countries" , "I can ship (anag.)" , "Latin" .)
