Get down to business in a powwow with a foreign country (4,6)
I believe the answer is:
talk turkey
'get down to business' is the definition.
(both can mean to talk frankly)
'powwow with a foreign country' is the wordplay.
'powwow' becomes 'talk' (I've seen this in another clue).
'with' is a charade indicator (letters next to each other).
'a foreign country' becomes 'turkey' (Turkey is an example. I am not sure about the 'foreign' bit.).
'talk'+'turkey'='TALK TURKEY'
'in a' is the link.
Can you help me to learn more?
(Other definitions for talk turkey that I've seen before include "discuss matters seriously" , "Speak frankly (about the Christmas dinner?)" , "Discuss business - gobble?" , "(In business) discuss frankly" , "Discuss a matter straightforwardly" .)
