as mentioned here, 3rd Mi-26 delivered to China. I wonder why they don't just order like 8 and get it over with. It's clear that they have a requirement for Mi-26 until the domestic heavy helo project completes.
Maybe they don't want the Russian's catching the blood in the water and pull a Il-76/Il-78 stunt? (Raising price, delaying production)
Better to order incrementally.
