China’s Huawei sues to challenge US security law
SHENZHEN, China — Chinese tech giant Huawei is challenging a U.S. law that limits its sales of telecom equipment in the U.S. on security grounds as the company steps up efforts to preserve its access to global markets for next-generation communications.
Huawei Technologies Ltd.’s lawsuit, announced Thursday, asks a U.S. court to reject as unconstitutional a military-spending provision that bars the U.S. government and its contractors from using Huawei equipment.
It comes as the biggest global maker of network equipment fights a U.S. campaign to persuade allies to shun Huawei. That threatens to block access to major markets as phone carriers prepare to invest billions of dollars in next-generation cellular networks, known as 5G.
