Huawei, the world's biggest producer of telecoms equipment, said it welcomed reports that Britain would allow limited use of its equipment in new 5G networks.

"We welcome reports that the UK government is moving towards allowing Huawei to help build the UK's 5G networks," a spokesperson said.

"While we await a formal government announcement, we will continue work cooperatively with the government, the industry and their evidence-based approach to network security."

A security source said Britain will allow Huawei restricted access to non-core parts of the 5G network but block it from all core parts of the system.

Meanwhile, the Chinese Ministry of Foreign Affairs (MOFA) spokesperson said on April 24 they are "learning about the situation."

China hopes that other countries will provide a fair and equitable business environment for Chinese companies, the spokesperson said.
