The Harvard University Asia Center ran an Islam in Asia Seminar Series that included several presentations on Islam in China.
Videos of two other presentations from the series are available on the Center’s vimeo channel.
Nancy Steinhardt (University of Pennsylvania), “The Mosque in China”
Kevin Caffrey (Harvard University), “Chinese Muslims and Revitalizing Islam in Southwest China”
You can watch my talk, “The First Chinese Translation of the Qur’an: Ma Dexin’s Interpretive Hermeneutics” here.
