Censorship in Taiwan (officially the Republic of China) was greatly relaxed when the state moved away from authoritarianism in 1987. Since then, the media has generally been allowed to broadcast political opposition. Today, the focus of censorship is slander and libel, cross-Strait relations, and national security.
In 1941, during the Second Sino-Japanese War, the second volume of the book "Inside Asia", by John Gunther, was prohibited and censored by the Republic of China (ROC, then based in Chongqing), since portions of it reported on certain things in Northwestern China which Chinese Muslims were doing.
In much of the martial law period in Taiwan (1948–1987), the Kuomintang-led ROC, as an authoritarian state, exercised strict control of the media. Parties other than the Kuomintang, such as the Chinese Youth Party and China Democratic Socialist Party, were banned and media advocating either democracy or Taiwan independence was banned. Li Ao, a famous political activist in Taiwan, nationalist, and intellectual, had over 96 books banned from sale. Writer Bo Yang was jailed for eight years for his translation of the cartoon Popeye because the translation was interpreted as a criticism of leader Chiang Kai-shek. Taiwanese-language media was also banned, and children who spoke Taiwanese in school were physically punished. The revision of Criminal Acts against seditious speech in 1992 ended the persecution of political opponents.
