How the US is trying to maintain dominance of the advanced semiconductor industry and limit China's ability to develop its own
The US has long dominated the advanced semiconductor industry and is going to great lengths, and expense, to stop China from catching up.
The tiny computing components are essential for almost anything that runs on power these days — from home appliances to consumer technology like smart phones, computers and cars, through to defence systems, satellites, AI systems and weapons of war.
On top of pumping billions of dollars in subsidies and other incentives into its industry, the US has sought to build alliances with South Korea, Japan, the Netherlands and Taiwan to boost production.
It has also taken steps to drastically restrict China's ability to access the critical technology, also known as microchips.
But experts warn the latest suite of US moves in the so-called "chip wars" could also backfire, and push China's industry to develop its own advanced semiconductors.
