In a "Clean Hong Kong" commercial, he urged the people of Hong Kong to be more considerate with regards to littering, a problem that has been widespread for decades. Furthermore, in an advertisement promoting nationalism, he gave a short explanation of the March of the Volunteers, the national anthem of the People's Republic of China. When Hong Kong Disneyland opened in 2005, Chan participated in the opening ceremony. In the United States, Chan appeared alongside Arnold Schwarzenegger in a government advert to combat copyright infringement and made another public service announcement with Los Angeles County Sheriff Lee Baca to encourage people, especially Asian people, to join the Los Angeles County Sheriff's Department.
