HONG KONG -- Tencent Holdings has temporarily halted new sign-ups to the widely used Chinese version of its WeChat messaging app, in a sign of how Beijing's tightening regulatory net is affecting the country's tech giants.
Tencent said on Tuesday that new registrations for the Weixin messaging app, which has more than 1 billion users in China, would be suspended to facilitate a security upgrade to meet the latest legal requirements.
