"The campaign will influence young people's perception of smoking and make the epidemic less attractive to them," she said.

To encourage public participation in the campaign, the foundation has distributed more than 1,000 T-shirts with the slogan "Say No to Forced Smoking" to volunteers, primarily in 10 major Chinese cities, including Beijing, Shanghai, Guangzhou, Nanjing and Hangzhou, according to Zhang Jing, publicity officer of the foundation's Beijing office.

Business tycoons such as Robin Li, founder and CEO of Baidu.com, and film stars such as Fan Bingbing, are among the volunteers, she said.

At a ceremony on Tuesday, high-ranking Chinese officials including Vice-Minister of Health Yin Li, Vice-Minister of Science and Technology Zhang Laiwu, and Zhao Baige, executive vice-president of the Red Cross Society of China, posed for a group photo with Bill Gates to show their support for the campaign. Peng Liyuan, China's anti-smoking image ambassador, also attended the ceremony.

All of them wore the anti-smoking T-shirts.

Bill Gates participated in the video shoot for a public service announcement of "Say No to Forced Smoking," which is produced by the foundation and China's Social Media for Social Good Alliance, composed of leading Chinese Internet enterprises such as Sina, Tencent and Baidu.
