Revolutionary Chinese New Year for each part of Russian Federation (8)

I believe the answer is:

chechnya

I'm a little stuck... Click here to teach me more about this clue!

'part of russian federation' is the definition.
(I know that Chechnya is part of Russia)

'revolutionary chinese new year for each' is the wordplay.
'revolutionary' becomes 'Che' (Che Guevara the Marxist revolutionary).
'chinese' becomes 'ch' (abbreviation).
'new year' becomes 'ny' (abbreviation).
'for each' becomes 'a' (I can't justify this - if you can you should believe this answer much more).
'che'+'ch'+'ny'+'a'='CHECHNYA'

Can you help me to learn more?

(Other definitions for chechnya that I've seen before include "Rebellious state" , "Quasi-autonomous region of southwest Russia, capital Grozny" , "Republic in the Russian Caucasus" .)

I've seen this clue in The Guardian.
