"Huawei has no connection to the cyber security issues the US has encountered in the past, current and future," Huawei founder and Chief Executive Officer Ren Zhengfei said in a statement.
The comment from Zhengfei was part of a statement talking about Huawei's selection for deployment of 4G (LTE) network in New Zealand.

The allegations in the report were denied by Chinese military.
