One of those English speaking cities is Neom [0]. I think they want to build it into a tech/tourist planned city.
The Mediterranean and South East Asia is littered with these futuristic planned cities. I was anchored off the coast of Malta near this KSA financed "Smart City" [1]
A city should last for centuries, at least, but it's hard to say if international tourism (as we know it) will recover within the next handful of months.
