China bans US memory chip giant Micron Technology, calls it national security risk

China says products made by US memory chip giant Micron Technology are a national security risk. The country's cyberspace regulator CAC announced on Sunday that America's biggest maker of memory chips poses serious network security risks. The CAC did not give details of the risks it said it had found or in which Micron products it had found them.

It means the firm's products will be banned from key infrastructure projects in the world's second-largest economy. It is China's



first major move against a US chip maker, as tensions increase between Beijing and Washington.

The announcement is the latest development in a deepening row between the US and China over the technology crucial to economies around the world. The long-running dispute has seen Washington impose a series of measures against Beijing's chip making industry and invest billions of dollars to boost America's semiconductor sector.
