China switches on superfast 5G network

China has rolled out 5G across 50 cities. It’s not the first country to install the technology, but it's the first to make it available on such a large scale. The launch happened two months ahead of schedule, as China powers ahead in the race to 5G – a race that earlier in the year, Donald Trump said America would win. This comes amid the ongoing US-China trade war, where 5G technology is a key battleground. The US has boycotted Chinese 5G tech provider Huawei, saying it poses a security risk, and is urging other countries to follow suit.
