Finance Minister P Chidambaram has said that there is a huge opportunity for foreign investment in India as the government focuses on rapid infrastructure development in the country. He told newsmen in Washington that the total investment requirements for power, roads, ports and civil aviation during the 12th Plan period is projected at one trillion dollar, nearly half of which is expected to come from the private sector. Mr. Chidambaram is in Washington to attend annual plenary meeting of International Monetary Fund and the World Bank. He said, this provides an ample opportunity for foreign investments to reap benefits from the high returns from India. He said, the Indian Government is promoting Public-Private Partnerships as an effective tool for bringing private sector efficiencies for delivery of quality public services.
