Gavin Williamson’s comments – reported by the Times – came after some nations restricted use of the firm’s products in 5G networks over security concerns.
MI6’s head recently said Britain faced decisions on Chinese ownership of tech.
The UK says China is behind hackers targeting commercial secrets. Huawei denies any link to the Chinese state.
