Databases also make the list, and again nothing from Western devs made the cut. But Alibaba Cloud's PolarDB is mentioned, as is Tencent’s TDSQL and a handful of other made-in-China efforts.

That's a big one.

Unless Chinese firms have been straight-up stealing trade secrets and code from the likes of Oracle and have produced such a blatant knock-off of their software that in any other country, they would have been sued out of existence, I can see a five week transition being messy-as-fuck.

Transitions to new database systems take months or even years to implement, not the 5 weeks mandated by the Chinese Communist Party. This is especially the case when you're dealing with important stakeholder data, huge data volumes and/or statutory requirements like financial reporting.
