Google and Android system start to cut ties with Huawei

SAN FRANCISCO (AFP) – US Internet giant Google, whose Android mobile operating system powers most of the world's smartphones, said Sunday it was beginning to cut ties with China's Huawei, which Washington considers a national security threat.

In the midst of a trade war with Beijing, President Donald Trump has barred US companies from engaging in telecommunications trade with foreign companies said to threaten American national security.

The measure targets Huawei, a Chinese telecoms giant in Washington's sights that is listed by the Commerce Department among firms with which American companies can only engage in trade after obtaining the green light from the authorities.

The ban includes technology sharing.

''We are complying with the order and reviewing the implications,'' a Google spokesperson told AFP.

The move could have dramatic implications since Google, like all tech companies, must collaborate with smartphone makers to ensure its systems are compatible with their devices.

Google will have to halt business activities with Huawei that involve transfer of hardware, software and technical services that are not publicly available – meaning Huawei will only be able to use the open source version of Android, a source close to the matter told AFP.

Huawei will no longer have access to Google's proprietary apps and services, such as the Gmail email service.
