In a stealth arms race over the 5G networks that will remake the internet, the US has been pressuring allies to freeze out Chinese companies

Over the past year, the United States has embarked on a stealthy, occasionally threatening, global campaign to prevent Huawei and other Chinese firms from participating in the most dramatic remaking of the plumbing that controls the internet since it sputtered into being, in pieces, 35 years ago. The administration contends that the world is engaged in a new arms race — one that involves technology, rather than conventional weaponry, but poses just as much danger to America’s national security. In an age when the most powerful weapons, short of nuclear arms, are cyber-controlled, whichever country dominates 5G will gain an economic, intelligence and military edge for much of this century.
