Huawei has admitted "room for improvement" in its product design processes in an open letter to the UK Parliament – but strongly refuted allegations of spying.
"The governments in some countries have labelled Huawei as a security threat, but they have never substantiated these allegations with solid evidence.
He claimed Canada has to date "not taken any restrictive measures against Huawei products"; New Zealand "turned down" a single 5G proposal, but the "regulatory process is still ongoing"; and Australia has raised "extra requirements for the supply of 5G products".
"Even in the US, existing legislation only restricts the use of federal funds to buy our networking hardware and services; there are no legislative restrictions on Huawei's business activities," Ding added.
Huawei cited a study of Chinese law by Clifford Chance that concluded the People's Republic does not oblige vendors to plant backdoors or other eavesdropping methods in telco equipment, and no sanctions exist against a company which has refused such a request.
Seven years ago Huawei established the UK facility in Banbury, Oxfordshire, nicknamed The Cell, which allows UK spy crew GCHQ access to its software code.
