Read: Port of Chabahar and deeper energy links on the agenda as renewed modes Iran Link Response to a question about Iranian cooperation with foreign parties in the construction and development of the port, Rastad said: « Iran, India, and Afghanistan is a trilateral dyed agreement, known as the Chabahar Agreement, which aims to raise the level of transit in the port and exploit its capabilities and potential. » India had initially proposed a plan for the construction of a 900 km railway line, Chabahar-Zahedan-Hajigak, which would link Chabahar to the mineral-rich Hajigak region of Afghanistan.   In 2011, seven Indian companies acquired rights to the Hajigak mine in central Afghanistan, home to Asia`s largest seeded iron ore. The Indian government had committed $2 billion to infrastructure development.
 In May 2016, a moU was also signed to finance the Chabahar-Zahedan railway section project of the Chabahar-Zahedan-Hajigak Railway (60) as part of the North-South Transport Corridor, by the Department of the International Indian Railways.  After the end of the bilateral talks between Modi and Rohani, key government sources said: « India is very interested in paying all oil taxes, given the looming economic relations with Iran. » According to Iranian media, the Phase I development agreement for the port of Chabahar is considered to be India`s opposite pole for the development of the deep-water port of Gwadar in Balochistan, Pakistan, which opens onto the Arabian Sea and allows China access to the Indian Ocean. At a joint press conference after the signing ceremony, Rohani said the new agreement was a symbol of cooperation between the three countries. However, on 14 July 2020, Iran announced that it would continue to build the Chabahar-Zahedan railway independently and cited delays in Indian funding as the reason for the breakdown of the partnership.  The Iranian government plans to complete the rail link by March 2022 and is using the Iranian National Development Fund to complete the project.  He continued: « In the early stages of the construction and development of the port of Chabahar, we first entered into a contract with an Indian operator, and the operator continues to cooperate with Iran on a fixed-term contract, and we are preparing to enter into a 10-year contract for the transfer of construction operations (BOT) with the Indian side. , with $85 million in Indian investment in port equipment. India has been uneasy in observing Chinese funding for a strategic port in Gwadar, Pakistan, which New Delhi believes will allow Beijing access to the Indian Ocean region.
