It isn't - A new breakthrough allows cheaper fabrication of a long known iron alloy, iron nitride, that yields a magnet more than 2X the strength of neodymium at half the cost and that cost will go down once fabrication is streamlined.
China has the global monopoly on rare Earth's and has been saber-rattling with Japan and Taiwan over territorial rights where major sea deposits lie.
Neodymium accounts for over 90% of global rare Earth demands, but iron nitride will also replace other rare Earth's.
American ingenuity is still alive and well.
China can stick to making trinkets for now.
Great video on the topic, I'm a big "Two Bit Davinci" fan, Ricky Roy's great - https://www.youtube.com/watch?v=xInA76a1eVs
