What is the significance of the Indus River for India and its neighbours?

The Indus River is crucial for both India and Pakistan, as it supports agriculture, provides water for drinking and irrigation, and influences the economies of the regions it flows through. The river's management is significant for bilateral relations, as disputes over water rights can lead to tensions. The Indus Water Treaty, signed in the 1960s, aims to regulate the use of the river's waters between the two countries.
