These meetings are being organised ahead of Prime Minister Manmohan Singh's state visit here in November.

Meanwhile, Kamal Nath, India's Minister for Road Transport and Highways held a roundtable in America's financial capital focusing US investment attention on India's roads and highways. India's road network of 3.32 million km is second only to the United States and is in need of major upgrades.

Speaking to premier US engineering, construction and investment firms, Nath said: 'This is one of the most important projects the Government of India has ever undertaken. Roads and Highways cross the country and touch every facet of life, as well as provide vital connectivity for trade and commerce.'

India is set to launch the world's biggest Public Private Partnership programme that will result in the development of 15,000 km of roads and highways over the next three years at a cost of $70 billion. The current five year plan calls for $500 billion in upgrades to India's infrastructure sector-with about one-third of the investment coming from the private sector.

The roundtable was hosted by the US-India Business Council, in partnership with the Confederation of Indian Industry (CII).
