Regional leaders, including Indian Prime Minister Narendra Modi, are in Nepal for a two-day meeting of the South Asian Association for Regional Cooperation.
During the summit, leaders from Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan and Sri Lanka are likely to discuss energy sharing.
They are expected to meet as a group and also hold bilateral discussions on the sidelines.
A meeting between Indian Prime Minister Narendra Modi and Pakistan counterpart Nawaz Sharif may also happen, although no official announcements have been made.
"I also look forward to holding bilateral discussions with other South Asian heads of state and government on the margins of the SAARC summit," Modi said in a statement on November 25.
