No location picked let alone land bought or planning permission approved but they've already announced they're building a city. You can just say anything I guess if you're a hip right-winger.
"worked" seems like an overstatement. This wikipedia page is great, just a catalogue of grand plans that never got off the ground. It's easy to see why. They're effectively asking the host government to create a breakaway state within their own country which will get all the foreign direct investment and do all the economic activity. That is a recipe for a power struggle and a civil war which could end with the racist techmen as dictators of a banana republic.
Actually a guy from Hong Kong had a plan to set up a new Hong Kong in Ireland a couple years ago right after the new laws/protests meant a lot of people decided to get out of Hong Kong. The Irish government politely stonewalled him. I had a vague notion it was meant to be in Meath, apparently it was meant to be "between Dublin and Belfast"....
