Member states will even be obligated to exclude Huawei from implementing 5G

Given the lack of adoption of the recommendations regarding “high-risk” service providers in the implementation of critical parts of 5G networks, the European Commission could make them mandatory. In this way, member states may have to exclude companies like Huawei from deploying 5G.

In Portugal, it was recently reported that the Supreme Security Council decided to exclude companies located outside the European Union, the United States and other OECD countries from 5G networks.  This decision will be based on the recommendations of the European Commission, not to resort to so-called "high-risk suppliers", which include companies from China.
However, it appears that Member States are not following these recommendations, so they may become mandatory. 
a financial times He said the measure is being analyzed because only a third of EU countries have already banned the use of technology from brands like Huawei from the most important parts of networks.  This would be information shared with the newspaper by "officials aware of the discussions" currently taking place.
However, the paper states that the commission is unlikely to force member states to take action during its current term, which ends in 2024.

The Huawei problem, for example, is one of the loudest, mainly due to the intervention of the United States.  The US government believes that the company may be a tool of espionage in the service of the Chinese government. 
Huawei keeps refusing to call.  For example, in the case of restrictions already known in Portugal, the company said in a statement that it "had no prior knowledge and was not consulted about this matter" and that it was still collecting information "about the nature of the assessment" and hoped to continue serving Portuguese customers.
On Twitter, Margrethe Vestager, Executive Vice President of the European Commission for Europe Adapting to the Digital Age, said: Congratulation At the time the Portuguese Cyber ​​Security Council made its decision. 
It should be noted that 3 years ago, in 2020, the European Union approved a set of recommendations called the "5G Toolbox", which provided for the exclusion of manufacturers deemed high risk from the core of 5G networks.
