> it is repeatedly reported that the Chinese authority is tougher than the FAA.
Except their government and regulatory structures are much, much more corrupt than their Western counterparts. Sure, they'll produce a document that'll say its safe but whats in the air is a totally different story. The same way lead-free products from China are full of lead. Everyone I know who resells from alibaba does lead testing on their own for every bulk shipment to avoid this. The problem is that bad. Then you have poison in baby formula, USB chargers that catch fire, and the slew of other concerning things that come out of China regularly.
So yeah, maybe the FAA should be a little skeptical of a certification from a corrupt one-party state eager to make its mark on the world as being competitive with the West and taking every shortcut to get there.
