Networking firm Cisco has been accused of working with the US army and Government to infiltrate China’s information networks.
China Youth Daily, a Chinese state media outlet, criticised the California-based company of creating "backdoors" in its routers to aid NSA spying operations.
Cisco "carries on intimately with the US government and military, exploiting its market advantage in the Chinese information networks, playing a disgraceful role and becoming an important weapon in the US exploiting its power over the Internet", it said on Tuesday.
Cisco has denied the allegations of the state-run news agency, according to the New York Times.
In a statement, Cisco spokesperson John Earnhardt said the networking firm did not provide any electronic back doors for the US government using its products.
"Additionally, Cisco does not monitor communications of private citizens or government organisations in China or anywhere in the world," he said.
Cisco also said it does not monitor the communications of both private and government clients anywhere in the world.
The allegations follow a similar accusation to those made against Huawei when it was seeking to break into the US market.
Last week, the US was also accused of ‘hypocrisy’ by China following the indictment of five Chinese military personnel on the grounds of cybertheft against American firms.
The Chinese Government has also reportedly ordered state-owned companies to break ties with Microsoft. Last month, China said Microsoft’s Windows 8 operating system (OS) would be banned on its government computers.
