- India and Pakistan signed the Indus Waters Treaty in 1960
- Under the treaty, India can use only 20% of the water of the Indus
- If India were to cut off water supply, it could trigger a crisis in Pak
At a press briefing, Foreign Ministry spokesperson Vikas Swarup, when asked whether cancelling the Indus pact was an option, said: "Eventually any cooperative arrangement requires goodwill and cooperation on both sides."
When pressed for a more specific response, Mr Swarup said: "For any such treaty to work, it is important for mutual trust and cooperation. It cannot be a one-sided affair."
India and Pakistan signed the Indus Waters Treaty, brokered by the World Bank, in 1960.
According to this agreement, control over the three eastern rivers - the Beas, Ravi and Sutlej - was given to India and the three western rivers - the Indus, Chenab and Jhelum - went to Pakistan.
Under the treaty, India can use only 20 per cent of the water of the Indus, which flows through it first, for irrigation, transport and power generation.
If India were to cut off supply to Pakistan, it could cause major crisis in that country as a majority of its areas are dependent on Indus water.
