Here are skyscraper development maps for China. They are not totally comprehensive but it's a start. (You can also click the "Built" checkbox on the left side of the pages to see all existing buildings marked)
If anyone notices anything major missing please post information so that it can be added, thanks!
There are actually many more Chinese projects in the SSP database than what is shown on the maps but we need to know the actual locations of them.
