BTTT!
China purchased 24 S-70 from Sirkosky before Tiennamen Square and the embargo. They were purchased to operate at the higher altitudes possible with the S-70.
The have now created this, which does have some changes.
1) Five blade rotor instead of four.
2) Different tail rotor assembly.
3) Different landing gear.
4) Larger cabin.
So, they have made it their own, though it is clearly based on those S-70s they purchased.
