In 2007 Chthonic were featured as a second stage act at the 2007 Ozzfest tour. The band named that year's tour "UNlimited Taiwan Tour" to draw awareness to the fact that the United Nations does not recognize Taiwan. This symbolic protest was covered by the US mainstream media, including ABC television, "New York Times", "Los Angeles Times", "Washington Post", and others. That year they also toured with Nile, Dååth, Obituary, Cradle of Filth, Marduk, Ensiferum, and 3 Inches of Blood while playing in several European countries. A book titled "GUTS!", featuring a diary of the UNlimited Taiwan Tour, was released in Europe and Asia.
