STOCKHOLM (AFP) - Chinese telecoms group Huawei has appealed against Sweden's decision to ban it from the country's 5G network for security reasons, a legal filing obtained by Agence France-Presse on Friday (Nov 6) showed.

The ban, announced by the Swedish Post and Telecom Authority (PTS) on Oct 20, "lacks legal basis, violates fundamental human rights, violates fundamental EU legal principles... and is incorrect in substance", Huawei wrote in its appeal to PTS and the Stockholm administrative court.

If carried out, it would cause "exceptionally comprehensive and irreparable damage" to its business, Huawei added.

PTS has said that its ban, which also affects Chinese company ZTE, is in line with new legislation that took effect in January 2020, following an examination by Sweden's armed forces and security service "to ensure that the use of radio equipment in these (5G network) bands does not cause harm to Sweden's security".

Carriers using any existing Huawei and ZTE installations must also remove them by January 2025, PTS said.

The United States alleges that Chinese companies are used to spy for Beijing - allegations which China denies - and has piled pressure on allies to cut Huawei from their telecommunications infrastructure.

Huawei said in its appeal there was "no concrete evidence of a cyber security threat" posed by the company, and insisted that "the Chinese state cannot order Huawei to spy".

China's embassy in Stockholm had previously urged the Swedish government to review its decision.
