US national security under threat due to Huawei ban, technology companies warn Trump administration
- Ban may slow research and development and harm US military technology, which relies on fast and capable chips

The companies are making the claims in applications for licences that would let them do business with Huawei after the prohibition goes into effect in August, according to people familiar with the licensing process.
Huawei is the second largest mobile phone maker in the world and a leading maker of telecommunications equipment crucial to the roll-out of the next generation of wireless technology known as 5G. It is also the third largest buyer of US-made computer chips, according the Semiconductor Industry Association.
The Trump administration placed Huawei on the Commerce Department’s entity list in May for violating US sanctions on Iran, prohibiting US-based companies from doing business with it. It then granted a 90-day reprieve of the effective date to soften the blow to US companies.
