ZTE has hit back at the United States’ newly-imposed ban on American companies selling to the Chinese networking vendor.

The US Department of Commerce issued the ban on April 16th, claiming that investigations by its Bureau of Industry and Security (BIS) found ZTE has lied about its dealings with Iran and North Korea, rewarded execs who did those deals and violated other trade laws besides.
