Mind your MANRS as politics meets network security Share Copy China Telecom has joined the global routing security group MANRS, just as America's communications regulator decided to formally investigate whether the company was a national security threat. “The Mutually Agreed Norms for Routing Security (MANRS) officially accepted China Telecom as a participant in the network operator program, announcing that three of China Telecom's major networks have met its community-led routing security standards,” reads the announcement. The big reveal appears to be both a response to the US government’s position – which has been engaged in an anti-China campaign during the Trump administration – and a test of the MANRS body, which was set up to fix routing errors and yet risks being dragged into global politics.
