China takes a page from US red states' agenda

Books about the Tiananmen Square massacre, Hong Kong protest movements, and other subjects deemed politically sensitive by Beijing have been removed from the former British colony’s public libraries in the lead-up to the 34th anniversary of the killings.

Hong Kong media have reported a marked increase in the number of book and documentary removals, which have been growing since the authoritarian clampdown on Hong Kong’s pro-democracy movement and the introduction of the national security law in 2020. It has resulted in a significant curtailing of political freedoms in the city and multiple arrests.

Ming Pao reported that about 40% of politically themed books, magazines and videos available at the end of 2020 were gone, 96 of them removed this year.
