Explanation:

India signed a historic deal to develop the strategic port of Chabahar in Iran and agreed on a three-nation pact to build a transport-and-trade corridor through Afghanistan that could help halve the time and cost of doing business with Central Asia and Europe. Developing the Chabahar port was seen as crucial for India because it will not only allow New Delhi to bypass Pakistan and access global markets but also counter China’s expanding influence in the Indian Ocean  region. But the project’s land route through Afghanistan remains a security headache.
