Name the ports that were created to substitute Karachi and Chittagong.

NCERT (2026-27): “The British used the ports as suction points of the resources from their hinterlands. … It was expected that the country’s Independence will reverse the process, but the partition of the country snatched away two very important ports, i.e., Karachi port went to Pakistan and Chittagong port to the erstwhile east-Pakistan and now Bangladesh. To compensate the losses, many new ports, like the Kandla in the west and the Diamond Harbour near Kolkata on river Hugli in the east were developed.”
