US-China tech war: China becomes world’s top semiconductor equipment market as Beijing pushes local chip industry

Mainland China topping the list for the first time ever. South Korea is investing a lot more than usual. Taiwan is stable. The US is down.

Will be very interesting how the chip situation will look on the other side of the current shortage. The shortage is all over, not just for high end processes. The high end processes will probably still be done by SK, Taiwan and the US but a lot of the lower end will go to China.
