In a letter to parliament, Justice Minister Ferd Grapperhaus said a task force set up to examine the threat from state-backed spying in 5G networks had concluded that was a "sufficient answer to the threat".

While the Dutch intelligence agency AIVD has issued several warnings this year about Chinese and Russian spying, a key advisory body last week said the Dutch should follow Britain and Germany's lead and not exclude Huawei completely.

Grapperhaus said the task force carried out a risk assessment with the three big Dutch telecommunications providers, KPN, T-Mobile and VodafoneZiggo.

Dutch telecoms companies will now have "extra high standards" for equipment suppliers, he said.

Grapperhaus ordered an inquiry last week when telecoms company KPN suffered a nationwide network outage that knocked out emergency service numbers for nearly four hours.
