News has surfaced in the past day that Cambridge University Press has accepted demands from Chinese state agencies to remove published content from its databases available within the People's Republic of China.
The news surfaced yesterday (August 17, 2017) when a letter from China Quarterly editor in chief Tim Pringle, addressed to the journal's editorial board, began circulating on social media. According to that letter, the Press, which has published China Quarterly since 2001*, had removed over 300 articles and book reviews from its China-accessible content in response to a request from the General Administration of Press and Publication of the PRC.
The China Quarterly has now released a public statement about this event (also here). Cambridge University Press has released its own statement confirming the removal of content. It includes the statement that "we complied with this ... request ... to ensure that other academic and educational materials we publish remain available to researchers and educators in this market."
Cambridge University Press is the publisher of many other high-profile academic titles in Asian Studies, including the Journal of Asian Studies, which it has published since 2007.*
Here is an accessible summary of the story to date, including verbatim copies of Dr. Pringle's original letter and the CUP statement.
