Well, this is a direct consequence of the trade wars the POTUS has (largely) needlessly started simultaneously.
Is this part in reference to China being justified? The US should have leaned on its EU/EA allies to form a united front there instead of picking fights with all of them simultaneously plus declaring Canada a national security threat. It's been so self-defeating and it'll take a long time to fully repair. In any case, I still wouldn't of placed tariffs on Chinese goods. The problem with them is intellectual property and trade secret theft within critical industries such as aerospace and semiconductors.
If you want to fuck China's ambitions up
badly, it doesn't make a whole lot of sense to deny them IC's from Intel, Qualcomm, Micron, Microchip, Texas Instruments, NVIDIA, et al. when such a significant portion of US semiconductor revenue is made through Chinese sales. You place export controls on the
chipmaker's suppliers and choke off access to materials, machinery, equipment, software and services they require to raise their own domestic industry.
Namely these industrial high tech firms in particular. One of them is based in the Netherlands (ASML) and the other Japan obviously, this is where it would be nice to utilize the relationships with the allies you've been so keen to throw under the bus instead.
