Having persuaded many of their billionaire peers in the US into giving away chunks of money, Bill Gates and Warren Buffett are travelling to China to host newly minted Chinese tycoons to sell them on the value of philanthropy.
But the fear of being seduced into giving up part of their fortunes might have scared some of the tycoons away from a dinner that the crusading US billionaires are hosting in Beijing this month.
The exclusive list of attendees includes Zhang Xin, CEO of Chinese SOHO China, the real estate developer, and Wang Chuanfu, head of BYD, the car and battery maker, who counts Mr Buffett as an investor.
But according to the Chinese media, the head of the Bill and Melinda Gates Foundation in Beijing is worried that some invited guests might be reluctant to come.
