That doesnt even make sense.  So the Russians, in letting the Chinese build RUSSIAN choppers, are now competing against....Russian choppers?  Where is the upside to this?

I suspect MIL gets some cash, makes parts for export and then sends the parts to the PRC for final assembly...  Until, of course, the Chinese copy the parts, cancel the deal and start vending on their own (e.g. J-11B clone of SU-27).

 

In short - fool me once shame on you ... fool me twice shame on me.
