The update can be identified by firmware version V12.5.3.0.RFACNXM and is currently rolling out in China. But, we can expect Xiaomi to release Android 11 for the International model very soon. Xiaomi has also added April 2021 security patch, which is not the latest but fixes a bunch of security vulnerabilities. It is currently under the ‘stable beta’ phase, so it may take some time to reach all the Mi 9 devices in China. You can manually check for the latest update by heading to Settings » About phone » System update.
