Is there any stopping Tata? It seems to be buying stuff on a daily basis. Today’s crop of purchases include Boston’s Ritz-Carlton Hotel, and, of more note for the truck industry – in which Tata is India’s biggest player – it now looks as if it is about to embark on a £5.5 billion bid for Corus Steel. So much for the emerged markets investing in the emerging: although whispers suggest that Volvo and DC are getting close to taking a lump of Ashok and Eicher respectively, it’s beginning to look as if the investment traffic between Europe and India is running on a very much two-way street.
