Several key suppliers are reportedly cutting off Huawei after the Trump administration added the Chinese telecom equipment and smartphone giant to a trade blacklist last week. According to Bloomberg, semiconductor companies Intel, Qualcomm, Xilinx and Broadcom will no longer supply Huawei until further notice. This follows another report earlier today that Google has suspended some trade with Huawei, leaving it with access only to the open-source version of Android.

In addition to impacting Huawei’s business, the blacklisting has ramifications for telecom providers who are getting ready to launch 5G networks. In China, the three big telecoms (China Mobile, China Unicom and China Telecom), which are all heavily reliant on Huawei, may be forced to delay 5G rollout. Meanwhile, U.S. carriers, especially smaller ones, may have to spend millions of dollars replacing Huawei equipment they have already installed or looking for new suppliers.
