Ministerial-level talks aimed at addressing the massive imbalance in trade between India and Bangladesh are due to get under way in the Bangladeshi capital, Dhaka.
It is estimated that India exports 15 times more goods to Bangladesh than are traded in the other direction.
The Indian foreign minister, Yashwant Sinha, will represent India at the meeting of the Joint Economic Commission.
It is only the fifth such meeting in more than 20 years, though they are intended to take place annually: the last was six years ago.
Delhi has said it's keen to reach a free trade agreement, while Dhaka is pressing for duty-free access to Indian markets for an experimental six-month period.
The movement of people across the border, the sharing of water from rivers that run through both countries, and transit facilities across Bangladesh for Indian goods are also expected to be on the agenda.
