Indian metals-to-oil conglomerate Vedanta is looking for a global company to partner with on expansion projects worth $20 billion across zinc, aluminium, copper, iron, steel, oil, gas and power, as per a tender document. The billionaire Anil Agarwal-led conglomerate -- set to split into four entities, Vedanta Aluminium, Oil and Gas, Power, Iron and Steel -- had earmarked the funds to invest in metals and mining and hydrocarbons in the next three years. Vedanta did not give specifics for the current tender, which was issued last week.
