Zoom is to let users opt in and out of specific data centre regions as part of the video conferencing app's latest security update.
The new option comes in response to concerns that data from meetings was sometimes being routed through data centres in China, which critics argued was a security risk.
Zoom said its centres in the country have "always been" geofenced, meaning that data generated outside of China would not move through the country.
However, Zoom chief executive Eric Yuan admitted that in the rush to meet demand during the coronavirus lockdown some best practices were not implemented and some meeting data may have been routed through China.
