India and Iran on 17 February 2018 signed agreements including Tehran leasing to New Delhi operational control of part of the Iranian east coast port of Chabahar for 18 months.

The $85 million project, just 90 km from the China-sponsored Gwadar port in Pakistan, creates a transit route between India, Iran and Afghanistan, bypassing Pakistan. India is trying to develop Chabahar as a way to gain access to the markets of central Asia as well as Afghanistan.
