Vedanta Resources, the UK-listed mining group, is planning to invest $20bn in India in the next four years to expand its metals, mining and electricity generation operations in the country. The move by Vedanta, which controls Sterlite Industries, India's biggest producer of non-ferrous metals such as aluminium, copper and zinc, would follow recent acquisitions such as its $2.6bn takeover of US copper producer Asarco last month. Demand for copper in India was growing 8-10 per cent year-on-year, aluminium 10-12 per cent and zinc 13-14 per cent, Vedanta said.

India needs to add the equivalent of about half the electricity generating capacity of the UK each year - or about 30 gigawatts - if it is to maintain its present rapid rate of economic growth, a new report shows. Yet the country in the past decade has managed to build an average of only 4GW of fresh capacity a year, a fraction of what the study by McKinsey & Co estimates will be required if the economy is to continue to expand at 8 per cent a year.

Seven years ago, the Jatias, a Mumbai hotelier family, bought land in the city's derelict former textile mills district that was partly occupied by slums and was faced by a large shanty town - hardly where most would site a five-star hotel. But this week, after years of navigating red tape, the 202-room Four Seasons Mumbai became the first luxury hotel of its size to launch in the city's south in about 20 years.
