Video conferencing giant Zoom suspended the account of a group of US-based Chinese activists after they held a meeting on the platform to commemorate the Tiananmen Square crackdown.

"We had to keep it secret," he said.
Humanitarian China's Zoom account was shut down on 7 June, the group said. "I'm very angry that even in this country, in the United States … we have to be prepared for this kind of censorship," Mr Zhou told SCMP.
