“None of us should participate, consciously or unconsciously, in promoting a spiralling tightened society with more and more controls. I don’t think anyone really enjoys living in that kind of social atmosphere.”

Hu has generally been known for toeing the official line and was a prominent critic of the 2019 anti-government protests in Hong Kong. He also mocked the US’ handling of the pandemic on both Chinese and international social media platforms such as Weibo and X, formerly known as Twitter.

But in Wednesday’s post, he urged people to avoid frequent boycotts and attacks on individuals, saying that these would only have a negative effect.

Hu wrote on Weibo that society should have “room for mistakes” and avoid growing anxiety and fear.

A mainland-based political analyst, who spoke on condition of anonymity, said it was a little surprising that had Hu voiced such concerns, and suggested that he may have received a sign that some important officials are also reflecting on the situation as the economy faltered.

But it was still unclear whether there was a sign that overall ideological control would be relaxed, the scholar said.

In October President Xi Jinping told the Communist Party’s national congress that there had been “overarching and fundamental changes in the ideological landscape” in the country.

He said “the party’s new theory for the new era has been embraced by the people” and “core socialist values are resonating with the public … and the online environment has seen continuous improvement”.

Hu’s call for a more open society might be a symptom of a growing tension between ideological control and economic policy in China, said Rana Mitter, a professor at the Harvard Kennedy School.

Earlier this year similar concerns were raised by Wang Wen, executive dean of the Chongyang Institute for Financial Studies at Renmin University, who noted that the concept of openness in Chinese society “has become somewhat lagging and conservative, and in particular, institutional opening up at a local level is slowing down”.

Wang had also previously been vocal in defending Beijing’s official line, including a report published in August 2021 criticising the US handling of the pandemic, describing its response as the “world’s number one failure”.

Wang told a free-trade forum in May that some local officials saw the flow of logistics, information and capital as “sensitive and even very dangerous”. He said they also viewed normal international academic and research exchanges as sensitive and must seek instructions from their superiors.

“Insufficient opening up, leading to poor reforms, is an important reason why China’s development potential has not been fully released at present and the momentum of economic recovery is still insufficient,” he said.

Mitter noted that while the party’s preference was for a very tight ideological environment, the economy was still sluggish and there was a sense that entrepreneurship and growth were hard to stimulate.

“A growing economy depends on free flows of information and a sense of predictability for business. This means less top-down control and more opportunities for wider society to experiment,” he said.
