Thailand bans textbook on national security grounds

Thailand's revered royal family remains off-limits for criticism under a strict defamation law, often accused of squashing opposition. Bangkok has now banned a textbook on national security grounds, citing its content about the Thai monarchy. Editor Pavin Chachavalpongpun, a vocal critic of the monarchy living in Japan, claims the book was outlawed due to its coverage of the royal family.

The Routledge Handbook of Contemporary Thailand, published in English in August, includes chapters on the monarchy in the 21st century and the government's use of the lese-majeste law. National Police Chief Samran Nualma signed an order on Wednesday, stating the book poses threats to national security, country unrest, and social morality.

Police can seize and destroy the banned book, with offenders facing up to three years in prison or a fine of up to 60,000 baht ($1,800). The editor expressed disappointment in the ban, suggesting people may resort to digital copies instead. He also noted that the ban might actually boost visibility for the book. In 2023, Pavin's previous book, Rama X: The Thai Monarchy under King Vajiralongkorn, was similarly banned, with police citing the cover and content as insulting to the monarchy and damaging to public peace and morality.
