Alphabet Inc’s Google has suspended business with Huawei that requires the transfer of hardware, software and technical services except those publicly available via open source licensing.

Reuters reported on Sunday that the move is a blow to the Chinese technology company that the U.S. government has sought to blacklist around the world.

A Google spokesperson said the company is “complying with the order and reviewing the implications” without giving details.

The move could spoil Huawei’s smartphone business outside China.
This means that tech giant will immediately lose access to updates to Google’s Android operating system. Future versions of Huawei smartphones that run on Android will also lose access to popular services including the Google Play Store and Gmail and YouTube apps, Reuters reported.

The Trump administration had added Huawei Technologies Co Ltd to a trade blacklist, immediately enacting restrictions that will make it difficult for the company to do business with U.S. counterparts.

The U.S. Commerce Department later said it was considering scaling back restrictions on Huawei to “prevent the interruption of existing network operations and equipment.” It was not immediately clear on Sunday whether Huawei’s access to mobile software would be affected.

The extent to which Huawei will be hurt by the U.S. government’s blacklist is not yet known as its global supply chain assesses the impact. Chip experts have questioned Huawei’s ability to continue to operate without U.S. help.
