Chinese companies have to teach [content moderators certain] information, so that they can then attempt to memory-hole it. AI doesn't completely obviate that, but to the extent that you can program in some of that stuff, like the Tiananmen Square Massacre, you don't have to educate actual humans on these things that you want memory-holed."

— Jessica Batke, co-author of "The Locknet: How China Controls Its Internet and Why It Matters," on how AI is being used to facilitate censorship by Chinese cyberspace authorities and platform moderators

CDT’s “404 Deleted Content Archive” Summary for September 2025

CDT presents a new monthly series of censored content that has been added to our “404 Deleted Content Archive.” Each month, we will publish a summary of content blocked or deleted (often yielding the message “404: content not found”) from Chinese platforms such as WeChat, Weibo, Douyin, Xiaohongshu (RedNote), Bilibili, Zhihu, Douban, and others. Although this content archived by CDT Chinese editors represents only a small fraction of the online content that disappears each day from the Chinese internet, it provides valuable insight into which topics are considered “sensitive” over time by...

Despite New Law to Facilitate Reporting of Public-Health Emergencies, COVID-Whistleblower Zhang Zhan Sentenced to Four More Years in Prison

Citizen journalist and COVID-whistleblower Zhang Zhan, who spent four years in prison for her in-depth reporting from Wuhan in the early days of the pandemic, was sentenced to another four years in a closed-door trial in Shanghai on September 19. International diplomats and observers were denied entry to the trial, and it is not known whether Zhang had any legal representation. Press-freedom and human-rights groups condemned the latest sentence, widely viewed as retaliation for Zhang’s continued outspokenness about China’s human-rights violations against prisoners, political dissidents, and...

Ahead of Global Women’s Summit in Beijing, More Feminist Content Blocked on WeChat

In the run-up to the Global Women’s Summit slated for October in Beijing, which will mark the 30th anniversary of that city’s influential 1995 U.N. World Conference on Women, some WeChat accounts focused on feminism and women’s empowerment have been blocked or had their content deleted. Earlier this month, feminist blogger Jiang Chan (姜婵, Jiāng Chán) had her official WeChat account blocked. The account now displays a message saying that it has been blocked, and that the content cannot be viewed because it is in violation of Cyberspace Administration of China (CAC) regulations. Jiang hasn’t...

Journalist’s Hong Kong Visa Denial and FCCC Report Underscore Declining Press Freedom

“After six years of reporting in Hong Kong, and at eight months pregnant, I’m very sad to be leaving my colleagues, friends and the place I’ve called home,” wrote senior Bloomberg News reporter Rebecca Choong Wilkins in an X post on Saturday. As other outlets confirmed, the Hong Kong government refused to renew Choong Wilkins’ visa in what many journalists and media organizations have described as the latest blow to press freedom in the city. David Pierson at The New York Times provided more information on the incident: The journalist, Rebecca Choong Wilkins, was not given a reason for her...

Interview: Jessica Batke and Laura Edelson on China’s “Locknet”

In June, ChinaFile published a new report, "The Locknet: How China Controls Its Internet and Why It Matters"—the product of 18 months’ work by Jessica Batke, ChinaFile’s senior editor for investigations, and Laura Edelson, assistant professor of computer science at Northeastern University. The report gives a concise but thorough overview of China’s online censorship system, including the motivations behind it and the mechanisms by which it is implemented. It expands on the familiar image of the "Great Firewall" as a perimeter barrier, adopting a broader...

Interview: Badiucao and Melissa Chan on Their Graphic Novel, You Must Take Part in Revolution

You Must Take Part in Revolution is a graphic novel by Badiucao, political cartoonist and former CDT contributor, and Melissa Chan, a journalist who in 2012 became the first reporter to be expelled from China in more than a decade. The book was conceived in the wake of the 2019 Hong Kong protests, and follows the divergent paths of three friends in Hong Kong and Taiwan from their involvement in the protests through to 2035. CDT: I’m sure anyone reading CDT is familiar with each of you separately. How did the two of you come to join forces? Melissa Chan: I’d interviewed Badiucao for a...

Similar themes have featured prominently on CDT in recent months, from uproar over the "4+4" fast-track for medical qualifications to commentary on the decline of former "golden ticket" degrees like computer science and the resurgent appeal of official careers.

Censorship Smothers Criticism of Military Parade

A host of measures intended to stifle dissent allowed Beijing’s military parade last week to take place without any major disruptions. The following is a summary of some of these examples of censorship and control. Some of these measures were implemented before the parade began. A recent censorship directive, leaked online and later translated by CDT, advised cyber-regulators to remain vigilant against a long list of “ideological risks” related to the upcoming military parade and other events during the third quarter of the year. Last week, Laura Bicker at the BBC detailed how Beijing...

Fight Over “Correct” Historical Memory Permeates China’s War Anniversary Commemorations

China is scheduled to host a large-scale “Victory Day” military parade on September 3 to mark the 80th anniversary of the end of World War II (referred to in China as the “War of Resistance Against Japanese Aggression.”) China and Japan’s diverging narratives around the war have generated tension between the two countries. The Japanese government has reportedly asked foreign leaders to skip next week’s parade in Beijing due to its alleged anti-Japanese overtones, leading the Chinese government to lodge a protest in response. An article in the Global Times claimed that the Japanese...

Translation: Special One-Month Reconnaissance Operation Against “Overseas Cyber Forces”

A pair of recently surfaced screenshots appear to offer unusual detail about a special month-long operation, held in Beijing and involving over 40 Ministry of Public Security computer specialists from around the country, to combat “overseas cyber forces” in the battle for public opinion. The apparently leaked internal instructions from the Ministry of Public Security are likely to be the result of an email breach. They include the names and locations of many of the computer-specialist officers, as well as the name and contact information of the individual in charge of the operation. At some...

Construction on Tibetan Megadam Fuels Ecological and Social Concerns

After Beijing granted authorization in December, construction on what would be the world’s largest hydropower dam has now begun. The site is located along the Yarlung Tsangpo River in southeastern Tibet, and it has drawn criticism from Tibetan rights groups concerned about social and ecological impacts, and downstream countries concerned about the potential weaponization of water flows. Helen Davidson at The Guardian summarized the massive scale of the proposed project: Construction of the world’s biggest hydropower megadam has begun, China’s premier has said, calling it the “project of the...
