It’s not a ban but a control, and it seems to be a lot about machines and tools. Foreign companies can still get these but they have to partner with a state owned enterprise according to the article. So, US defense companies building gas turbines won’t be able to get Chinese tools to do so, this is going to make it hard to build warships. With a control order in aerospace tools it’s going to be hard to make drones, rockets engines and satellites, which you can’t fight without.This is a retaliation I didn't expect, I wonder whom it'll affect.
I think the biggest affected will be Ukraine, who will run out of everything they need starting July 1st. Russian companies can just partner with Chinese SoE’s and get the tools and components legally.
