Well China does have the benefit of just ordering the work to be done and funded by the government, rather than a random contractor dropping the ball over cost overruns or not quoting the next stage because they fear losing money. For example Rogers committed to building cell towers through the coastal mountains or rockies to ensure service on those transit routes, BC agreed to contribute a large amount to help. Rogers starts then cancels it all saying land acquisition or development is going to cost to much for the towers. Whereas if it were a government project it would just get done regardless of extra costs, and profit isn't a factor.
