Notes heartless move by way of working with African country, deporting the weak (9)
I believe the answer is:
memoranda
'notes heartless move' is the definition.
'memoranda' can be an answer for 'notes' (more than one memorandum). I'm not sure about the 'heartless move' bit.
'working with african country deporting the weak' is the wordplay.
'working with' becomes 'memo' (I can't explain this - if you can you should give a lot more credence to this answer).
'african country' becomes 'Rwanda' (country in Africa).
'deporting' indicates named letters should be taken away.
'the weak' becomes 'w' (physics symbol as in W-boson).
'rwanda' with 'w' taken out is 'randa'.
'memo'+'randa'='MEMORANDA'
'by way of' is the link.
Can you help me to learn more?
(Other definitions for memoranda that I've seen before include "Notes recorded for future use" , "Written messages or notes" , "Communications" , "Records" , "official minutes" .)
