Amid growing strain in India-Pakistan ties, the government is planning to fast-track four projects in Indus river basin to increase irrigation area in Jammu and Kashmir by nearly 2.05 lakh acres, weeks after India decided to "exploit to the maximum" the water of Pakistan-controlled rivers, including Jhelum, as per Indus Water Treaty.

'India needs to learn in Kashmir how to spread development.' 'Pakistan needs to learn in Balochistan how to spread development.' 'China needs to learn in Xinjiang and Tibet.'
