A review ordered by White House on the security risks posed by suppliers to US telecommunications companies found no clear evidence that Chinese telecom equipment maker Huawei Technologies had spied for China, according to Reuters.
Earlier this month, the US House of Representatives’ Intelligence Committee had said that Huawei and ZTE should be barred from doing business in US market as they pose a security threat to the country.
Reuters, citing two unnamed sources, who said that a 18-month-long classified review found Huawei’s products were risky due to vulnerabilities in them that could prove favorable for hackers.
White House National Security Council spokeswoman Caitlin Hayden was quoted by Reuters as saying that "The White House has not conducted any classified inquiry that resulted in clearing any telecom equipment supplier."
The spokeswoman also added that Huawei had been barred from participating in an emergency network for first responders a year ago due to US government national security concerns.
The White House investigation questioned about 1,000 telecoms equipment manufacturers about reports of suspicious activity and found nothing connecting back to China.
In October 2011, Huawei was excluded from taking part in the building of America’s interoperable, wireless emergency network for first responders due to US Government national security concerns.
Canada had indicated to bar Huawei Technologies from assisting to develop a secure Canadian government communications network due to possible security risks.
