Zoom has been distancing itself from its China operations, which had come under the scrutiny of human rights activists and privacy advocates.
The company announced in May that it would suspend new free user registrations in China and limit new user registrations to enterprise customers who sign up through authorised sales representatives.
But in June, Zoom came under fire when it was revealed it had shut an account belonging to a group of US-based Chinese activists who were attending an online video group chat to memorialise the Tiananmen Square massacre.
In a blog post, Zoom confirmed it had temporarily shut down the accounts due to request from China's government. It said that it had re-instated the terminated accounts and "will have a new process for handling similar situations."
Months earlier, security researchers discovered that Zoom re-routed some calls through its servers in China, even if those calls were placed outside China.
The company said that the re-routing took place in "extremely lmited circumstances" and that it took its mainland China data centers off of an approved list of backups for users outside of China.
