I don't know, Moscow upgraded its 3 airports in the last 10-15 years as well as opened a new one. You would imagine that everything left over from Soviet times needed a massive overhaul. Maybe the difference is whether you really need an airport, or when it is second to having a big public project to sink costs into?
