yes he did, but that was only diplomatic relations not industrial policy and tariffs. this was also done in the context of dividing the communist spheres.

mainland chinese manufacturing and trade in the 70s and 80s was still mostly garments, appliance assembly and so on. the kind of thing you see in bangladesh today - even vietnam has mostly developed past garment manufacturing.

the world leading electronics manufacturing and precision components only began in china after bill clinton invited china into the wto in 99/2000 and the heavy capital started to flow. even by then, I don't think the USG expected shenzhen to exist

china didn't really move from bicycles to private car ownership until the 00s.

I mean its easy to forget; if you said in 1985, 1990, 1995, 2000, maybe even 2005 that china would be the worlds largest producer of cars, electronic cars, smart phones, drones, etc, on track to develop its own EUV lithography, and that many chinese cities would have the highest living standards in the world, you would have sounded ludicrous. intel was king and nokia/blackberry/motorola were the giants in cellular
