India mentions the issues of the Rattle hydroelectric project and Kishenganga disputes as the reason for sending the notice.
The Indus Water Treaty was signed between the Government of India and the Government of Pakistan in 1960.
According to the treaty, the waters of Beas, Ravi, and Sutlej are controlled by India, and the waters of Indus, Jhelum, and Chenab are controlled by Pakistan.
India has 20% access to the water system and Pakistan has 80% access.
According to India, Pakistan has been “Intransigence” over the treaty.
It means refusing to agree upon the treaty.
For this reason, India has sent a notice to Pakistan to modify the treaty.
The Rattle power project is located in the Chenab River.
In 2013, the then PM Manmohan Singh laid the foundation stone.
The project started in 2018 after World Bank allowed India to move ahead with the project despite Pakistan raising concerns.
