"... The US Congress last year warned telecom
equipment supplied by Huawei and another
Chinese company, ZTE, could be used for spying
and called for their exclusion from government
contracts and acquisitions...."
"..Huawei, which was founded by former Chinese
army engineer Ren Zhengfei, was also barred
from tendering for Australia’s national
broadband network last year on security
grounds...."
Meanwhile,
".... Rival Chinese technology companies, ZTE
Corporation and Huawei Technologies, are
locked in a two-pronged court battle over the
control of a multi-billion-shilling tender to
supply police with a communication and
surveillance system. .."

This is economical propaganda
Uncle SAM will do anything to ensure they remain relevant and maintain their power.

Don't you remember how they use travel advisory to scare people from some countries! Yet we didn't see any travel advisroty after recent Boston bombings

Can US and anybody else trying to slander others prove that their own systems do not have any spying agents within?
