Chinese telecoms equipment maker Huawei Technologies sued the U.S. government on Thursday saying a law limiting its U.S. business was unconstitutional, ratcheting up its fight back against a government bent on closing it out of global markets, Reuters reports.
Huawei said it had filed a complaint in a federal court in Texas challenging Section 889 of the National Defense Authorization Act (NDAA), signed into law by U.S. President Donald Trump in August, which bars federal agencies and their contractors from procuring its equipment and services.
