"We are making this announcement based on our investigation and an information provided by our partners in the security area, as well as the results received by our allies," Navratil told reporters.
The Czech Interior Ministry said it had discussed the NUKIB statement and was awaiting further recommendations from the agency.
The representative of Huawei in the Czech Republic, Magda Teresa Partyka, refuted NUKIB's allegations that the products of her company allegedly posed a threat to the security of the republic.
"In the 30-year history of our company, it has never been revealed that Huawei has committed any wrongdoings in the field of cybersecurity. And thanks to this, we have become a reliable partner for all major telecommunications firms in the Czech Republic," Partyka said.
Huawei is the largest telecom infrastructure supplier in the Czech Republic for local mobile operators. The company's revenue in the country amounted to 6.55 billion Czech crowns (about $300 million) in 2017. Until 2022, Huawei plans to invest about $360 million in the Czech Republic and create a total of more than 4,000 new jobs.
The United States and several other countries have also raised security questions with regard to the Chinese telecommunications giant.
