Google Earth was last updated in this area in August 2024 but there has been very little movement since 2020 at all even when zoomed in.
You can see the area where the Silk City is meant to go, further explanation on the video with good overlay maps, but there is literally nothing here.
I think we can assume the Silk City is a dead project unless anyone can find any furthe information? Assumed to take 25 years but they have to start at least some time?
