Shanghai?
So not one of the cheaper smaller cities targeted for new development, and not Beijing, the political centre.
"Peking" was the Shanghai pronunciation of "Beijing", and Shanghai was one of the Treaty Ports. It's always been part of the interface between China and the West. So, like Hong Kong, it's been disfavored recently as Beijing has sought to assert cultural supremacy by de-emphasizing the importance of western cultural influence. Investment has been preferentially directed to other areas, and free-trade import/export has been discouraged.
So, why put a new development in an expensive, disfavored, export oriented city? It's probably not because the location is expensive and disfavored.
