Google has reportedly suspended some parts of its business with Huawei in the latest blow for the troubled Chinese firm.
Google will suspend any business requiring the transfer of hardware and software products, except those covered by open source licences, Reuters reported, citing a source close to the matter.
The move means Huawei will immediately lose access to updates to the Android operating system, which it currently uses for its smartphones, while its products outside China will also lose access to apps and services including the Google Play Store and Gmail app.
Details of which services will be affected are still subject to internal discussions at Google, according to the report.
The Chinese tech firm would still be able to access the version of Android available through an open source licence. But Google will stop providing Huawei technical support and collaboration for Android and Google services, the source said.
However, the move may not come as a surprise to Huawei, which earlier this year confirmed it had built its own operating system as a contingency plan in case of a US ban.
It comes after US President Donald Trump last week signed an executive order effectively banning American companies from doing business with Huawei amid concerns about the risk to national security.

The Chinese company last week hit back at the ban, saying it would only serve to harm US interests and insisting the impact on its own growth would be minimal.
Google and Huawei have been contacted for comment.
