Google said Monday its basic services on Huawei smartphones still will function following US sales curbs, but the Chinese tech giant faces the possible loss of other features and support.
The announcement highlighted the growing damage to Huawei from Washington's order. The company has said until now US accusations it is a security threat have had little impact on sales outside the United States.
Huawei Technologies Ltd., which uses Google's Android operating system in its smartphones, said it would continue to provide security updates and service. It gave no indication which map, photo or other services they might lose.
The Trump administration's order targets China's first global tech brand and ratchets up disputes with Beijing over technology, trade and cyber-security.
Google, a unit of Alphabet Inc., said it is complying with and "reviewing the implications" of the requirement for export licenses for technology sales to Huawei, which took effect Thursday.
"We assure you while we are complying with all US gov't requirements, services like Google Play & security from Google Play Protect will keep functioning on your existing Huawei device," said Google on Twitter.
Google allows smartphone manufacturers to use Android and its basic services for free. But transfer of hardware, software or services to Huawei or technical interaction would be restricted by the US order.
That would strip Huawei phones of Google maps and other services that require direct support. That might hurt Huawei where consumers can pick other brands that carry the full suite of Google features.
The US government says Chinese suppliers including Huawei and its smaller rival, ZTE Corp., pose an espionage threat because they are beholden to China's ruling Communist Party. But American officials have presented no evidence of any Huawei equipment serving as intentional conduits for espionage by Beijing.
