It's a long-running feud that has worsened in recent months as a dry spell focuses attention on Pakistan's growing water shortage. Three days of talks in March ended with both sides trading barbs and failing to reach a resolution.
The issue was raised on Thursday when the leaders of the two countries met at a regional summit in Bhutan and agreed on the need to normalize relations, the Pakistani side said.
Further complicating the situation, Islamic extremists are trying to capitalise on allegations that India is stealing water from glacier-fed rivers that start in the disputed territory of Kashmir.
