You have set the bar too low.
CLMV - Cambodia Laos Myanmar Vietnam are considered the laggards in ASEAN.
The development gap that persists has to be addressed. ASEAN's initiative for that purpose IAI has pumped in quite a lot of money and assistance.
As usual, Singapore and our Thai friends and allies pumped in the most funds. As expected.
Less developed countries grow faster.
Myanmar, Laos and Cambodia are all growing on par with Vietnam, if not faster.

Nothing indigenous about that plane.
Not the avionics, not the landing gear, not the APU, not the engine, not even the propeller or whatever else you can think of.
The plane did not even sell (well enough).
Tens of countries have made (the exterior of) aeroplanes.
Even students can assemble some non-agile turboprop aeroplane.
