Lam Wing-kee, a former Hong Kong bookseller who became an internationally recognised symbol of resistance to Chinese political repression, has died in Taiwan at the age of 70. Lam was one of five people associated with Causeway Bay Books — a shop in Hong Kong known for selling politically sensitive titles critical of mainland Chinese leaders — who disappeared under mysterious circumstances in 2015, later revealed to have been detained by Chinese authorities. After his release, Lam publicly detailed his experience of mainland detention and eventually relocated to Taiwan, where he continued to speak out about threats to civil liberties in Hong Kong.
