China Bans Overseas Tech IPOs

China is formally creating rules to ban IPOs in overseas markets for technology firms with data security risks. The rules may also include companies with—quote—ideology issues—unquote. The move comes after investigating cybersecurity problems with Didi Global ($DIDI@China) days after its U.S. IPO. Under the new rules, Chinese regulators will ban IPOs when companies collect massive amounts of data or generate content that could pose a security risk.
