> it seems like they could speed things up by just scrapping the GFW and physically disconnecting their internet from the rest of the world

If you do that, international commerce for China grinds to a complete halt (though ik one very large F50 that is in the process of completely decoupling in the next 2 years)

Especially because this kind of an en masse disconnection means completely disconnecting Chinese assets abroad from their mainland HQs.

Down the grapevine, I have heard some provinces testing that kind of a whitelist, but I'm not sure how true that is.

If an actual nationwide whitelist is implemented, I think that is proof enough that war be coming. Even Roskomnadzor didn't try implementing a similar system until the 2022 escalation.

That makes sense, but at least China has to pay a cost for keeping it kind of opened but mostly closed.

It is also really hostile for foreign tourists. You'd be surprised how many people still go to China and have all their trip plans stored in Google docs...doh. Although if you come with a foreign SIM and use roaming, you circumvent the GFW automatically for some reason.

That's because when your SIM is in international roaming, traffic is routed by the local telco to a tunnel back to the home telco provider. This ofc decreases margins significantly (because those bytes are routed via fiber or satellite by a Transit Service) and is why roaming costs are so high.

Oof. You'd have to be living under a rock to not know that Google is banned in China, but I guess some tourists just aren't tech savvy, so who am I to judge.

> China has to pay a cost for keeping it kind of opened but mostly closed

Not really. As an individual you are definetly paying a performance cost in the form of low latencies and speeds, but this is also why edge computing solutions (eg. Compute offloading, packet size optimizations, etc) are heavily researched by Chinese players compared to Western players. In isolation, it's a good forcing function for innovation.

That said, it is absolutely 1984-esque.

Also, a lot of these innovations seem to be a result of the Urumqi and Lhasa riots from 10-15 years ago as well as Tahrir Square, so clearly maintaining the political status quo seems to be top of mind.

It's bad for business, but China (and especially Xi) has seemed to have taken a very statist approach after the 2015-16 financial crisis.

We hosted an ACM conference in 2011 in Beijing. One of my friends came, first trip to China, really smart guy just finishing up his PhD in EECS at UCB, but OMG did he mess that one up. We had to use the guest wifi in my office so he could make offline copies. If you aren't used to it, and don't follow China closely, you could be very technical and still be caught off guard. Lots of people will tell you China is just a normal tourist spot like Japan, Thailand, or Indonesia, but it really isn't.

I was in Beijing for those. A lot of things blocked afterwards, we slowly lost more services that we had previously. I would say 2008 was a peak for Chinese internet liberalization (and well, lots of other liberalization, I also spent 6 months in 2002 so can compare), and then it just tanked from that point on to present. They made a show for the Olympics and then decided they didn't need to bother anymore. It doesn't help that Xi is much more assertive and autocratic than Hu was.

Until a couple years ago, it was fairly common to smuggle VEOM, Airtel, and Ooredoo sims in much of Xinjiang and Tibet, because the Uyghur and Tibetan diaspora largely uses WhatsApp to communicate as the Uyghur diaspora is largely in the CIS, Turkey, and Pakistan and the Tibetan diaspora in India, Nepal, and the US.

Oh boy! That sounds rough, but also makes sense.
