Bryant also cautioned against a disruption in cross-border investment, as her company helps bring in investment from around the world, especially China.
In 2019, Chinese visitors spent more than 1.3 billion dollars visiting the San Francisco Bay Area. For many of them, WeChat, with its ability to make payments, played a valuable role.
It was unclear how the administration could implement the ban on WeChat in mid-September. It could order Apple Inc and Alphabet Inc's Google to remove WeChat from their app store, or order the apps to stop offering access or updates to U.S. users.
In his latest report, TF International Securities analyst Kuo Ming-chi estimated that global iPhone shipments could drop by 25 to 30 percent if Apple is forced to remove WeChat from its global app store. Besides, the annual shipments of other Apple hardware devices, including AirPods, iPad, Apple Watch, and Mac, will be revised down by 15 to 25 percent.
Some users said they planned to access WeChat in the U.S. using a virtual private network (VPN).
Apple has spent years building China into a 44 billion U.S. dollars growth driver. In the second quarter of 2020, the company's revenue from the Chinese market accounted for over 15 percent of its total.
