Mobile network maker Nokia has started a legal challenge to a decision by the Romanian government to exclude it from selling 5G technology in the country.

Last year, Romania’s government approved a United States-backed bill that effectively barred China’s Huawei from supplying 5G network.

“We can confirm that in February we were advised that we had been denied the authorisation to provide 5G infrastructure equipment in Romania by the Romanian government,” Nokia said in a statement.

“We are seeking urgent clarification for the reasons for this decision and have instigated legal proceedings.”
