Human Rights Watch (HRW), a US-based advocacy group, has accused China of imposing sweeping censorship and tightening information controls in the wake of deadly flash floods that have devastated communities in Tibet and across the border in Nepal. The allegations, published on 1 September, detail a coordinated effort to suppress independent reporting and shape public narratives around the disaster.

Weibo Hashtags and Official Narratives

According to HRW, the Chinese social media platform Weibo — which operates under Beijing's censorship directives — prominently pinned a memorial hashtag, 'Mourning the victims of the Gyirong mudslide disaster', at the top of its trending topics, alongside eight other disaster-related hashtags. The lead post featured a China Central Television (CCTV) news anchor reading what was described as a Politburo communique, in which Chinese President Xi Jinping reportedly called on the country's top leaders to observe a minute of silence for the victims.

HRW noted that 'the victims' own voices are largely absent from the trending topics, which focus on the death toll, rescue operations, and the mechanics of the disaster.'

Journalists Barred, AI Images Deployed

Citing reports, HRW said journalists in China have been barred from the disaster zone and from interviewing affected families, leaving them entirely dependent on official information channels. The rights body further alleged that Chinese authorities have punished at least 10 people for 'rumormongering' related to the disaster.

HRW also reported that Chinese official media relied on AI-generated images and videos purporting to depict the likely origins of the mudslide. Meanwhile, original footage that circulated internationally — showing Gyirong Port on the Chinese side of the border being overwhelmed by floodwater as people fled — was reportedly being censored within China.

A Familiar Playbook, HRW Says

The rights body drew direct parallels with past disasters in China, describing the response as a recurring pattern. 'Information controls can make it harder for families to locate loved ones, and hamper understanding of the disaster and any future response,' HRW stated. It added: 'As with previous disasters, the choreography is familiar: restrict information, control the narrative, and praise the leadership's resolve and rescue efforts. AI may polish the performance, but the script remains unchanged.'

HRW said it has long documented pervasive censorship and self-censorship across China, particularly in Tibetan areas, where people can reportedly be imprisoned for allegedly undermining national security simply by sharing information with the outside world. Foreigners, including journalists and independent investigators, are barred from entering Tibet without official permission.

The Disaster: Origins and Cross-Border Impact

The catastrophic flood that struck Nepal's Rasuwa district originated in the Tibetan region of China on 26 August. It swept through the transboundary Bhote Koshi River, leaving hundreds dead and causing widespread destruction across the Himalayan nation. The disaster's cross-border nature has made independent verification of the full scale of damage particularly difficult, given the restrictions on access to the Tibetan side.

As rescue operations continue on both sides of the border, the question of information access — and who controls it — remains as consequential as the disaster response itself.
