Back in 2017, Ian Tsung-yen Chen, a politics professor at Taiwan's National Sun Yat-sen University, took part in a book-writing project with academics from mainland China, Hong Kong and Taiwan. They gathered research papers to study how education has shaped the national consciousness of people in the three places.
As the group of scholars sent the book to the Chinese University of Hong Kong for publishing last year, they were notified that the book publication had been suspended indefinitely. "I was told no universities in Hong Kong could publish it anymore, after the protests began," Chen said. "The deteriorating political sentiment in Hong Kong has really affected academic freedom."
