Bill embraced by leader of China in region of that country (5)
I believe the answer is:
macao
'china in region of that country' is the definition.
The definition suggests a singular noun which matches the answer.
'bill embraced by leader' is the wordplay.
'bill' becomes 'ac'.
'embraced by' indicates putting letters inside.
'leader' becomes 'mao' (Mao is an example**).
'ac' placed within 'mao' is 'MACAO'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for macao that I've seen before include "Former Portuguese colony in China" , "Portuguese province" , "Eastern city" .)
