Google has halted some businesses with Huawei as the US government has “blacklisted” the Chinese company.

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, Beijing Youth Daily reported, citing Reuters.

Google has cut the Chinese smartphone maker Huawei off from some updates to the Android operating system and new Huawei smartphones will also lose access to popular Google apps such as YouTube and Maps.

Huawei will lose Google’s security update and technical support, and will only be able to use the pubic version of Android, it said.

Google said it was complying with the order and reviewing the implications. Huawei declined to comment.

Industry insiders were quoted as saying that the restrictions would have little impact on domestic markets, but it could hurt Huawei’s users outside China as they will need Google services.
