New Delhi/IBNS: India had, on Jan 25, issued a notice to Pakistan for modification of the Indus Waters Treaty (IWT) of September 1960 following the Islamic country's "intransigence" on its implementation, media reports said Friday.

The notice was sent to Islamabad through respective Commissioners for Indus Waters, as per provisions of the treaty.

According to India, the action was necessitated as Pakistan has refused to discuss and resolve the issue of the Kishenganga and Ratle Hydro Electric Projects for the last five years, despite New Delhi's efforts.

India is seeking modifications in the treaty to make it easier for Pakistan to enter into intergovernmental negotiations, within 90 days, and rectify the 'material breach' of IWT.

This process would also update IWT to incorporate the lessons learned over the last 62 years.

"India has always been a steadfast supporter and a responsible partner in implementing IWT in letter and spirit. However, Pakistan's actions have adversely impinged on the provisions of IWT and their implementation, and forced India to issue an appropriate notice for modification of IWT," NDTV reported quoting sources.
