MUMBAI: International development banks from South Korea, Japan and Germany have shown interest in funding multibillion-dollar industrial corridors coming up across the country, Delhi-Mumbai Industrial Corridor Development Corp chief executive Alkesh Kumar Sharma said. These belts with special manufacturing clusters and smart cities are expected to spur economic growth.Work has started at the first industrial corridor — from Delhi to Mumbai, cutting across six states, Sharma told ET. Four other industrial corridors in northern, central and southern India are at various stages of planning. “We have started getting a lot of enquiries.India has demographic dividend , while they have expensive economies and ageing population,” said Sharma at ‘ Make in India ’ week in Mumbai on Tuesday. “These countries have money and technology. They can train our local people to manufacture products here, which can later be exported.”He said export-import funds of South Korea and Japan, KfW Development Bank of Germany and some banks from Hong Kong are among those who have shown initial interest in the project in the last few months. “You invest in a country because you know the political system is strong and protective. Our Supreme Court, through its judgments, has proved that it is impartial and fair. This is going to help ‘Make in India’,” said Sharma, who took up the post four months ago.Japan International Cooperation Agency ( JICA ) has already committed $10 billion for the Delhi-Mumbai and Chennai-Bengaluru corridors and the Manila-based Asian Development Bank has offered $1 billion for the Chennai-Vizag corridor.The central government will invest $4.5 billion initially in the project. States’ contribution in the form of land is also being treated as equity. Sharma said 70% of funding will come from public and private partnerships. He is expecting a budget outlay of at least Rs 4,000-5,000 crore this year.Three phases of the Delhi-Mumbai industrial corridor, expected to be completed by 2040, will need $90 billion in funding. The investment cost of the other four corridors is being worked out. The government needs funding to build internal city infrastructure like roads, electricity, water supplies, telecom networks and waste management systems, and external infrastructure to connect these cities to nearest national highways, railway junctions or airports.These industrial corridors are developing smart industrial cities where they have a connectivity backbone. These industrial clusters will be connected to direct freight corridors and national highways that are part of the golden quadrilateral.
