Bangladesh has not only solved ALL its decades long territorial disputes with its neighbours - India and Myanmar quite recently. As of this day Bangladesh and both its neighbours have zero claims of even one square inch on each other's territories(land or sea).
It has also ratcheted up high economic growth far surpassing Pakistan...
and has already achieved social development indicators surpassing Pakistan.
I really wonder what makes you think that Bangladesh Govt is past centric. If you call all the above as past centric, I would only hope that other countries also become similarly past centric.
