According to some reports, AV 200 has been widely used by civil department, while AV 500, as I know, it is developed According to Algeria's requirement. AV 1000, I only know about the designation.
Well, I think if they want to, they will make it as the technology is not complicated. As I know, the biggest UAV we have is AV-1000, which has a maximum take-off weight for about 950 kg, and does not need an engine as powerful as AI-450
Problem is the Russian engine is still on paper, so our side is more prone to use D-136-2. Anyway, this project is on the early days, so we can not predict what will happen in future.
There is no attack helicopter UAV in China. Don't know if they have future goal to arm the helicopter UAV.
We have Y-20 and Y-9, so An-70 is useless for us as the two that we have has covered the lift range of An-70.
Things are quite tricky here. Motor Sich can supply us with D-136-2, so does Russian. So it means they have direct competition with Russian here, and to make Russian feel pain, they are...
In 1990s for the initial version
D-18T and D-136-2 may be in the induction list and on discussion for future induction, but not something like light helicopter. Ukraine is not every anti-China, and our relationship is not very bad at the moment.
The core engine of WJ-9 is the same as Turbomeca Arriel, so if WJ-9 is not good enough, then reverse engineered AI 450 could be worse considering French engine technology far ahead of Ukraine.
