Chan's video, shot Monday, highlights efforts to promote one of the Olympics' more low-profile events.

A rash of equine diseases and substandard quarantine procedures in China forced Beijing to hand the equestrian events to Hong Kong, which has a well-established racing circuit but few facilities for dressage and show-jumping events.

The Hong Kong Jockey Club, which controls horse racing in the former British colony, has spent about $100 million on upgrading existing venues and building new ones for the Olympic equestrian competition, which will take place Aug. 9 to Aug. 20.

In other promotional efforts for the Beijing Olympics, Chan also recorded the event's official one-year countdown song, "We Are Ready."
