I’ve only got two decades of civil engineering experience in Europe china and now the uk to draw on. I can’t provide a source for the absence of Chinese reporting on land costs because you can’t prove a negative. Although it should be blatantly obvious that comparing the cost of building something in the uk to the cost in china is simply pointless. Here’s a link to a high speed train collision in china that killed a heap of people: https://en.m.wikipedia.org/wiki/Wenzhou_train_collision And another one: https://www.cbsnews.com/amp/news/high-speed-train-derailment-china/ … and a link to construction labour deaths https://clb.org.hk/en/content/china’s-most-dangerous-industry-getting-more-dangerous
The point being that china has a very different equation when they go about doing things to here in the uk.
Frankly I shouldn’t have to do this for you.
You’re supposed to be providing sources about how the land was forcefully purchased at a low and unfair price. Not that trains derail.
As I stated, china don’t publish that information and it doesn’t take a genius to work it out. Troll.
When my beloved Arsenal built the Emirates, people said that they were low-balled. That claim is part and parcel with any forced possession. However asking you to prove that the valuations were low isn’t asking a lot.
