BEIJING — One of the world’s oldest and most respected publishing houses, Cambridge University Press, has bowed to pressure from Beijing and removed sensitive content on its site in China.

The content is published in China Quarterly, an academic journal run by the press. In a letter made public on social media on Friday, the editor of the journal, Tim Pringle, said Cambridge University Press had informed him that the authorities had ordered it to censor more than 300 articles related to issues like the 1989 Tiananmen Square massacre, Tibet, Xinjiang, Hong Kong and the Cultural Revolution. The publishing house’s site risked being shut down if it did not comply with the request, the letter said.

In response to the government’s actions, the journal issued a statement expressing its “deep concern and disappointment.”

“We note, too, that this restriction of academic freedom is not an isolated move but a further reflection of policies that have narrowed the space for public engagement and discussion across Chinese society,” the statement said.
