China is threatening an export ban on rare earth metals in response to Washington’s recent decision to impose restrictions on exports of high-end semiconductors to Beijing. This is not the first time that China has mooted such a ban, with rumours circulating since at least 2019 as well as formal threats in 2021.
What would be the negative consequences for China for a rare earth metal ban? China kept threatening a ban, but they never did anything about it, so what would be the negative consequences of such a ban and do they outweigh the benefits? They used it against Japan before, so I don't understand why they won't use it against Japan and the Netherlands.
