(Bloomberg) -- Chinese microblogging site Weibo Corp. is asking some of its users not to post negative content about the economy, a move that underscores concerns about sputtering domestic growth.

The social media service, often compared with X, sent notices to users warning them to “avoid expressing pessimism about the economy,” according to a memo circulating online that one recipient confirmed to Bloomberg News.

One Weibo user focused on finance, with more than 76,000 followers, said in a Thursday night post that they were privately told to post less about the economy, and instead shared a lighthearted video about US baseball. Another Chinese markets blogger, with more than 16,000 followers, posted a separate notice asking bloggers to “avoid crossing the red lines” particularly around economic or financial topics.

Weibo representatives did not respond to a request for comment.

The guidance from one of China’s most popular social media sites comes as the country’s top leaders seek to restore confidence, including by pledging to strengthen fiscal growth. In a Politburo meeting last week, top officials from the ruling Communist Party vowed to strengthen public opinion guidance on economic affairs. Mixed economic data on Friday showed that recovery after the pandemic remained slow, with weak consumer confidence and a lingering real estate crisis.

The Ministry of State Security said Friday that negative comments on the economy would endanger national security. “Various clichés intended to undermine China’s economy have appeared consistently, in an attempt to use false narratives to construct a ‘discourse trap’ and ‘cognitive trap’ that China is in decline,” the ministry said in a post on its official WeChat account. “This is an attempt to strategically contain and suppress China.”
