Google said consumers who already own Huawei smartphones are largely untouched for the time being.
"Google Play and the Google Play Protect security measures continue to work on existing Huawei devices," the spokesman added, adding more details.
But the company is heavily dependent on countries other than China. About half of smartphone sales last year were made outside of China, according to research firm Canalys and IDC.
Huawei said it is testing "the impact of US action on consumers," adding that it has worked on its own operating system for at least three years.
"Huawei has developed an alternative operating system in case it is needed," said Huawei spokesman Glenn Schloss. "We want to continue to operate in the Microsoft and Google ecosystems," he added.
Kill Huawei outside of China?
The consumer business, which includes smartphones, laptops, tablets, and wearable devices such as smartwatches, made the biggest contribution to Huawei's earnings last year. The division made nearly 349 billion yuan ($ 50 billion) in 2018, or more than 45% of its revenue.
For the millions of users outside of China, shutting down Google apps and services is "compromising the appeal of a Huawei mobile," said IDC analyst Bryan Ma.
"The ease of use of a Huawei cell phone outside of China is compromised and they are dead in the water," he added.
Theoretically, Huawei can try to convince consumers with more competitive hardware and innovation and after-sale a Huawei to persuade Google Apps to persuade phone, said Nicole Peng, analyst at Canalys.
However, there is evidence that "post-sale installation is a huge challenge for users unless they know what they are doing," Peng said.
"If customers find out that Huawei can not use the Google ecosystem on their cell phones, it will compromise their trust and they'll wonder if something is wrong with the device," she added.
Although customers could independently download Google apps on Huawei phones, cell phones may not have access to so-called Google Mobile Services.
Many third-party apps, such as Google Maps. According to IDCs Ma, most of these apps may no longer be supported on Huawei devices.
Without this access, "the Huawei phone is a building block," he said.
