Google is restricting future business with Huawei, cutting off access to its Android operating system and its popular apps, after the Trump administration escalated a crackdown on the Chinese tech firm.

Google’s suspension, first reported by Reuters, amounts to a major blow to the world’s largest telecommunications equipment-maker, which will no longer receive access and support for Google’s proprietary apps such as Gmail, YouTube and Chrome.

The open-source version of Android will still be available to Huawei, according to the report, but the Chinese tech giant will immediately lose access to updates to the operating system. And though existing Huawei users can still download popular Google apps through the Google Play store, they won’t be available on future Huawei handsets.
