With the 25th anniversary of the violent suppression of student protests on June 4, 1989 coming upon us next week, we spoke to Louisa Lim, a journalist for NPR who has written a book about the events of 1989 and their consequences. The People’s Republic of Amnesia: Tiananmen Revisited comes out on June 4, the day of the anniversary. Lim answered our questions about her book and the anniversary by email.
