Chinese telecom giant Huawei filed a lawsuit against the United States in a U.S. federal court in Texas, near Huawei's U.S. headquarters, saying Huawei had been unfairly banned from the use in U.S. government networks. The company hired a team of top U.S. lawyers to handle the proceedings. Some American analysts say the legal dispute will be an uphill battle. Huawei said it was compelled to take legal action as a last resort because the U.S. failed to produce any evidence to justify the restrictions on Huawei's business.
