Chowdhury was of the view that people expect the IPU can fill the void left by the South Asian Association for Regional Cooperation (SAARC).
"Looking at it from the point of view of people's aspirations, what I'm saying is that the SAARC was an unkept promise. I'm not saying we (IPU) are a replacement for the SAARC but...I think this is what people would like to see," he told PTI on sidelines of the South Asian Speakers summit.
Chowdhury, who is an MP from Bangladesh, said the SAARC is entirely political and it is at the governmental level, whereas the IPU is the platform led by people who are elected by the people.
"So I think there is a difference. When you are talking on people to people basis, you are more frank. You can easily talk about your differences," he added.

Emphasising on trade, he said inter-regional trade within South Asia is less than 5 per cent which is very low compared to the European Union or the African Union.
He added that IPU wants to create a structure and wants to add value to the ongoing discourse through the sustainable development goals so that it could give people the future they desire.
