Serbia has lot of experience and know how in that area which they gained trough producing raspberry which is most sensible fruit for handling and storaging, they could offer you good solutions.This could have something to do with Serbian Machinery/Methods/Labs that (I think) meet EU/FDA standards ?
This is relevant if BD is interested in exporting to those regions.
Other aspect of this meeting is interesting, i noticed couple of years ago certain number of construction workers started to work in balkan region from Bangladesh and with the trend of depopulation and migration towards EU this part of balkan already feels lack of working force and that could be main reason for this visit of their fm.
