Huawei has accused the US government of "using every tool at its disposal" to disrupt its business.
In a press release on Tuesday, the Chinese tech giant said the US had launched cyber-attacks to infiltrate its networks and was threatening its employees.
The firm, which was put on a US trade blacklist this year, did not offer evidence for the allegations.
Huawei has become a centrepiece of the trade dispute between the US and China.
In its press release, Huawei alleged the US had been unlawfully detaining its staff, launching cyber-attacks to infiltrate its internal information systems and that FBI agents were being sent to the homes of its employees to pressure them to collect information on the company./BBC news
