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.
