Speaking to Reuters, Huawei defended is independence.
"If the actions in the report are true, Huawei condemns such activities that invaded and infiltrated into our internal corporate network and monitored our communications," Huawei's global cyber security officer, John Suffolk, told Reuters.
"Corporate networks are under constant probe and attack from different sources - such is the status quo in today's digital age," said Suffolk, saying it was very successful in 145 countries.
He added that Huawei does not build 'back doors'.
The U.S. Pentagon said last year that a large number of cyberattacks against US targets appeared to be originating from the Chinese government.
In 2012, the US government had also said that Huawei's networking equipment posed a national security risk, something that caused the company to partiallyretreat from operating in the US market.
