China's multi-millionaire philanthropist

The US billionaires Bill Gates and Warren Buffett are hosting a dinner for some of China's richest people in Beijing on Wednesday. They are hoping to lean more about philanthropy in China - and perhaps persuade their guests to donate more money to charity.

One of those invited is multi-millionaire businessman Chen Guangbiao. He has already pledged to give away all his money when he dies.

Michael Bristow interviewed him at his apartment in Beijing.
