Why does Huawei 5g need a US license?

Huawei has a large number of 5G patents, but the use of 5G chips requires the consent of the US government. The restrictions on Huawei's 5G are more because the US government has imposed a series of sanctions on Huawei, which led to the blockade of advanced chip technology in the United States.

The U.S. government believes that Huawei is an agent of the China government, which may leak U.S. national security information and threaten U.S. national security. The US government is worried that Huawei's technology and equipment may be used to monitor the American people and infringe on their privacy. The US government accused Huawei of violating sanctions against Iran and North Korea and providing technical equipment and services to these countries. The US government accused Huawei of stealing the intellectual property rights of American companies and infringing their interests.
