Doesn't work. China's export controls on rare earths are product-based, not country based. You can buy motors, but not magnets.

China wants to move up the value chain. They don't want to continue to be the colony supplying raw materials (or even slightly refined materials) to the "first world". China wants to be building those electric motors - which is where the value & profits are located.

Buy the motors and take out the magnets then

I didn't say it would work, just clarifying the comment you were replying to.
