The 53-year-old actor, best known for his daredevil stunts, has recorded "We Are Ready," the official countdown song to the 2008 Beijing Summer Olympics.
He spent three hours recording the song during a recent trip to Beijing, Chan said in a blog entry on his Web site Wednesday.
Chan, star of the "Rush Hour" movies, dabbles in music and has released several albums.
He praised the lyrics of the Mandarin Chinese song composed by Peter Kam, who won a Silver Bear award for best film music at the Berlin Film Festival last year.
"Waiting year after year/ We can see into the future/ Together with hard work and sweat, we've created the five different (Olympic) colors," says one refrain.
Olympic organizers have also recorded a second Chinese version sung by more than 100 pop stars, Kam said.
He told The Associated Press in a phone interview that an English version of the song may be recorded.
Chan said in an earlier blog entry that he got goose bumps when he attended the official one-year countdown event in Beijing on Aug. 8.
"The ceremony made me very emotional and I said to myself, `That's our China, that's our day!' I felt this moment belonged to our China, this moment belonged to us," he wrote.
