TAIPEI, Taiwan — A Taiwan-based publisher who disappeared while in China has been detained for suspected violations of security laws, Chinese authorities confirmed on Wednesday, fanning concerns in Taiwan that Beijing is sending a warning to the island’s vibrant publishing sector.
The publisher, Li Yanhe, widely known by his pen name, Fu Cha, is a Chinese citizen who has been living in Taiwan since 2009.
His company, Gusa Publishing, is well known in Taiwan for books that cast a critical eye on China’s ruling Communist Party.
Mr. Li had returned to China early last month to visit relatives but fell out of contact shortly after, according to his colleagues and friends.
Mr. Li’s detention is “a strong blow and will have a chilling effect,” Bei Ling, a writer from China living in Taiwan, said on Wednesday.
