Yup most of Asia (maybe except Japan, Korea and Taiwan) aren't past the development phase where light engineering is a big export sector.
For China, it constitutes not only large factories and companies making motorbikes, but their small mom and pop companies who make sub-assembly parts for those motorbikes, such as wheels, springs, headlight assemblies, speed indicators, carburetors, handles, kick starter assemblies etc. Same for bicycles, flashlights, Locks, hand-tools (all the parts you can buy in Bongshal/old Dhaka) as well as pots/pressure cookers.
In the seventies and eighties, Japan (and later Korea and Taiwan in the nineties) was in that light engineering revolution. Today China, Thailand, Indonesia and Vietnam (as well as Bangladesh) are in those fields. But China is gradually moving past that stage while the others like Thailand and Indonesia have not. The only reason China is still in that phase is because of the almost unstoppable supply of low cost labor compared to smaller countries.
Some Chinese refer to their own country as the 'middle country ' due to not ALL it's people having a standard of living comparable to the developed world.
So I don't know how the Vietnamanese think of themselves as a fully developed country
