Global retail giant WalMart's disclosure that it spent around $25 million on lobbying with the US lawmakers on various issues including those related to opening of Indian multi-retail sector to FDI generated much political heat in India, but the lobbying revelation reports filed with the US Senate and the House of Representatives showed that WalMart was not the only US company to do that.

According to the quarterly lobbying revelation reports, more than 15 other large US companies have spent millions of dollars to lobby for their business interests in India.

These include computer giants Dell and HP, pharmaceutical giant Pfizer, telecom players like Alcatel-Lucent and Qualcomm, financial services firms like Prudential Financial and Morgan Stanley, as well as the Aerospace Industries Association of America and Alliance of Automobile Manufactures.

Alliance of Automobile Manufacturers spent around $8 million, Aerospace Industries Association of America spent nearly $2 million, and consumer goods maker Cargill spent $1 million; while Dell and HP spent nearly $2 and $1.5 million respectively, on lobbying for their Indian business interests.

AT&T, Boeing, Starbucks, Lockheed Martin, GE and Eli Lilly lobbied with US lawmakers on specific issues related to India.

While lobbying is a legal activity in the US, there are no specific regulations regarding lobbying in India.
