Bill Gates, co-chairman of the Bill and Melinda Gates Foundation, has a cameo role in a Chinese anti-smoking music video, which is part of a social media campaign launched by the foundation against passive smoking.

Feng Zhe, a gold medalist on the parallel bars in the 2012 Olympic Games, released his song Say No to Forced Smoking on Wednesday. Gates appears in the video wearing a T-shirt bearing the words of the song title.

Yang Jianyue, deputy director of the Gates Foundation in China, said the song is the latest initiative in a social media campaign that began in October. The foundation has joined with social media and philanthropic partners in calling on netizens to submit witty sayings against secondhand smoke.
