New deal with China to supply spicy food (9)
I believe the answer is:
enchilada
'spicy food' is the definition.
(I've seen this before)
'new deal with china' is the wordplay.
'new' is an anagram indicator.
'with' means one lot of letters go next to another.
'deal' put after 'china' is 'chinadeal'.
'chinadeal' with letters rearranged gives 'ENCHILADA'.
'to supply' is the link.
(Other definitions for enchilada that I've seen before include "Tortilla with meat and chilli" , "spicy dish" , "spicy food" , "Filled tortilla served with chilli sauce" , "Mexican food" .)
