Gates, Buffett bid to open wealthy Indians' wallets

NEW DELHI - Two of the world's richest men, software pioneer Bill Gates and investor Warren Buffett, are set to visit India this week to persuade the country's super-wealthy to part with more of their cash.

The pair made headlines last year when they said they would seek to get fellow billionaires to commit half of their wealth to good causes as part of the "Giving Pledge". So far, 59 rich Americans have taken the pledge.

But while charitable giving is widespread in countries such as the United States, it is less well established in developing economies such as India and China, where Gates and Buffett went in September on a similar mission.
