NEW DELHI: India is not just stopping at a trilateral agreement with Afghanistan and Iran to operationalise the strategically located Chabahar Port — gateway to landlocked Kabul and Central Asia — but is pulling all stops to raise funds for the project.After the PM announced $500 million in Tehran last week for the port complex, Delhi may host an international investors’ conference — to generate funds for Chabahar — with participation from all three stakeholders besides Central Asian states and international financial institutions, including the World Bank and International Monetary Fund.The Chabahar Port, in Southeastern Iran, needs massive funding for its full realisation of its potential including expansion, connectivity links (railway network) and Free Trade Zone. Keeping that in mind, three primary stakeholders are hoping to host an international investors’ conference in Delhi in the coming months, people familiar with the developments told ET.The stakeholders would approach all top global investors including World Bank and IMF. India would alone need funds worth $1.5 billion to build railway networks in Iran including a rail link from Chabahar to Zahedan that will connect the port to the entire Iranian railway network.India and Iran are discussing railway link along the Chabahar-Zahedan-Mashhad route, connecting the port with the Iranian cities of Zahedan and Masshhad, along eastern Iran, sources informed. The completed railway will extend 1,380 kilometres.A team from IRCON was in Tehran ahead of the PM’s trip to discuss this project and another railway connectivity projects in Iran. India will also supply steel rails to Tehran worth $400 million.India has extended $150-million credit line for making of jetties and berths at Chabahar port, and had earlier announced $20 billion for the entire port complex where it also wants to set up downstream projects, including fertiliser plants.
