That's a terrible example, not just because of technical inaccuracy because China is one of the few places in the world making vast capital investments - not just in production, but real estate, transport, power generation etc.

(Sibling comment is correct that SMT automated assembly is used for most parts, and a few large TH parts like connectors are soldered on at the end. Wire bondout of chips into chip packages and things like SD cards and USB sticks however seems to be more manual.)
