Beijing (AFP) - Human rights activists and some academics in China have had their WeChat messaging app accounts restricted in recent weeks, multiple people affected have told AFP, as Beijing cracks down on dissent before the Winter Olympics.
China hopes to make next week's Games a soft power triumph, although the lead-up has seen some Western powers launch a diplomatic boycott over Beijing's rights record and cybersecurity firms warn athletes of digital surveillance risks.
For China's ever-dwindling community of activists, the imminent arrival of the world's best athletes has triggered a familiar clampdown.
Eight individuals told AFP that their WeChat accounts had been restricted in some form since early December, with some unable to use their accounts entirely and forced to re-register.
The restrictions came as authorities detained two prominent human rights activists, lawyer Xie Yang and writer Yang Maodong, while a third rights lawyer missing since early December is believed by relatives to be in secret detention.
"This storm of shuttering WeChat accounts is too strong and unprecedented," said veteran journalist Gao Yu, whose account had features like group chat messaging permanently disabled for the first time on December 20.
China routinely suppresses the social media accounts and physical movements of dissidents during politically sensitive periods such as Communist Party gatherings in Beijing or key anniversaries like the 1989 Tiananmen crackdown.
A major Party Congress will take place towards the end of this year when President Xi Jinping, China's most authoritarian leader in a generation, is expected to further cement his rule with a third term.
The arrival of the Winter Olympics has presaged a clampdown similar to those surrounding other major events.
"The government now wants to make sure that people don't cross the line online to poke the facade of a perfect Winter Olympic Games," said Yaqiu Wang, senior China researcher at Human Rights Watch.
Ubiquitous app
Tencent's app WeChat is a mainstay of daily life in China, with users relying on it for a range of services including payments and scanning health codes that permit entry to public venues.
"I know many people who've been banned from posting in group chats or posting WeChat Moments lately," a Beijing lawyer whose account was restricted last month said on condition of anonymity.
Beijing-based writer Zhang Yihe said her WeChat group chat and Moments functions -- similar to Facebook's Wall or Instagram Stories -- were restricted on January 8.
Tsinghua University sociology professor Guo Yuhua confirmed her account was permanently blocked the same day, while prominent legal scholar He Weifang said he encountered the same on January 9.
"Isn't this equal to removing an individual from a public space?" said Zhang, adding she can now only send WeChat messages to individual users.
"Before and during the Olympics is a major sensitive period," added a Beijing-based activist whose account was restricted twice in the past two months.
Tencent, the owner of WeChat, did not respond to a request for comment.
Offline crackdown
In recent weeks, Chinese police have detained two prominent rights activists on suspicion of "inciting state subversion", according to official notices shared with AFP.
One of them, Yang Maodong, was unable to reunite with his wife in the United States before her death in early January.
Relatives of Tang Jitian, a human rights lawyer who vanished last month en route to an EU Human Rights Day event in Beijing, told AFP they believe he is being held under a form of secret detention commonly used against dissidents, possibly in his home province of Jilin.
"We don't know where he is.I've reported him missing to the police but with no result," said a relative who did not wish to be identified for fear of reprisal.
"They said it doesn't meet the requirements for filing a (missing persons) case and that he had scanned the Jilin province health code."
People arrested for national security offences in China can disappear for months at a time into incommunicado detention before authorities charge them or reveal their fate.
Both Jilin and Beijing's public security bureaus did not respond to requests for comment.
The International Olympic Committee said in an emailed response that it "has neither the mandate nor the capability to change the laws or the political system of a sovereign country", adding that it "must remain neutral on all global political issues".
Beijing Games organisers told AFP they "oppose the politicisation of sports" and were "not aware of these matters".
Meanwhile, those still free lament mounting restrictions on speech under the current political climate.
"The space for public discourse is getting smaller and smaller," said He.
