we all did hear about $7 billion airport.....
Dude that was back in 2010 and Hasina was talking nonsense as BD didnot have the fiscal resources at the time to be able to spend so much money on a unnecessary project.
In 2014, BD has allocated hundreds of millions in the current budget to get the Padma bridge, and the bridge will be built with BD's own internal financial resources within the next 4 years
BD's economy has just grown 6.2% and should be around 7% this year due to the instability of the election out of the way now. As the years pass, BD will be able to build even more projects with it's own money.
Since BD is small, the burden of infrastructure will be smaller for BD than for India and so BD will be able to build infrastructure quicker than India.
