Those airport were built couple of years ago. It will be good if you mention their present price. N the present airport will be built in 3 phase .... Time will require around 15 years. That is the reason why it is showing this high price.
Apart from Malaysia, Qatar has shown interest also to finance the project.
Yeah but the labour is much much cheaper in Bangladesh compared to say the UK and South Korea. I also doubt if it will be largest airport in South Asia.
Do you have any more info about this project? How big the terminal is going to be, capacity, built area, number of runways?
