Indiana Jones Explores Ancient China was an unpublished title in the Indiana Jones Explores series. It was advertised as the third book on the inside flap of Indiana Jones Explores Ancient Egypt and Indiana Jones Explores The Incas, with Indiana Jones Explores Ancient Greece to follow fourth. However Ancient Greece instead became book three and Ancient China wasn't released at all. A new title, Indiana Jones Explores The Aztecs, was added to the series list in subsequent books after The Incas release.
