BEIJING, CHINA -- China's Communist Party is giving all state offices three years to remove all foreign hardware and software.
That means replacing an estimated 20 to 30 million pieces of equipment in what could be a blow to U.S. companies like Microsoft, Dell and HP.
Analysts say the move aims to protect Chinese interests amid escalating tensions with Washington.
The U.S. has already targeted some Chinese tech firms, banning them from doing business with American companies and banning Chinese equipment from federal offices.
This comes just after Chinese tech giant Huawei announced it's moving its research center to Canada due to U.S. sanctions. Huawei's founder says the sanctions are preventing the company from communicating with its American employees.
The Trump administration placed Huawei on a trade blacklist in May for the company's ties to the Chinese Communist Party, which officials cited could be a national security issue.
The Chinese tech company is fighting back against new restrictions from the US Federal Communications Commission.
Huawei the world's largest telecommunications equipment maker and a leading smartphone brand, announced that it has filed a lawsuit in New Orleans challenging the FCC's decision to ban American carriers from using federal subsidies to purchase Huawei equipment.
The tech company argues that the FCC's latest embargo is unlawful as it provides no evidence of the national security threat that the company poses, ultimately violating the Constitution.
The Trump administration pushed back saying that installing Huawei's equipment in US networks could allow Chinese spies to eavesdrop on sensitive US communications.Huawei has denied the allegations, and says none of its products pose a national security risk.
