The US-China tech war is being fought across a bamboo curtain

It is becoming clear that the ongoing “tech war” between the United States and China is taking place along five fronts: semiconductors, network infrastructure, operating systems, platforms and content. While it was Beijing that first erected a defensive Great Firewall around its internet users over 25 years ago to censor content, it is now Washington that is on the offensive on all fronts.
