Are you a China watcher on the hardware side? I know there are people whose hobby is to keep track of more glamorous things like war planes, warships, artillery, tanks, and so on, but few who actually look at logistics. I'm sure there are pros who look at logistics, but hobbyists go for the glitz. Jeff Head has been tracking China's carrier development for a good long time, but I don't think I've seen anything about logistics.
Watching PDRChina used to be a job of mine, way back when. But, I’ve got no access to any real info and haven’t for decades.
The logistics is the thing to watch, though, imo.
More to the point than “watch logistics”, watch for large movements of troops within their own borders, and large fleet movements.
They’ll need work sorting out the log train and that’s done with large scale exercises.
Now, keep in mind I don’t watch careful so they might have already begun the process.
