Two US Senators, Republican Tom Cotton and Democrat Mark Kelly, have submitted a Bill proposing a ban on buying rare earths from China for government defence contractors. If the Bill, called Restoring Essential Energy and Security Holdings Onshore for Rare Earths Act, is passed, defence companies building weapons for the US will have to stop buying rare earth materials from China by 2026. The latter are often used in modern technologies.
"Ending American dependence on China for rare earths extraction and processing is critical to building up the US defence and technology sectors," Cotton said in an interview with Reuters.
The law is supposed to persuade contractors to use American rare-earths supplies. However, there is only one rare earths mine functioning in the US and practically no plants that can process them into powerful magnets and other materials and goods.
This is where the Bill becomes controversial. To help the contractors to fulfil their obligations in conditions of poor rare earths supplies in the US, the authors propose they should seek these materials from a reserve created by the Pentagon. However, this reserve is at present being filled by the very Chinese rare earth materials that the contractors will be banned from buying if the Bill is passed.
At the same time, the Bill inked by Cotton and Kelly contains no means to support the emerging (or rather reviving) US rare-earth industry. Major US defence companies did not comment on the Bill's proposals.
The US used to be a leader in production of rare earths, but later ceded the throne to China, which now controls most of the market. Beijing blocked exports of rare earth metals which are essential for modern technologies only once as it acted against Japan in 2019, but it warned it could do the same to the US.
The latter designated China as a potential adversary and a rival in the global arena during Donald Trump's administration. Joe Biden's administration made no attempts to become reconciled with Beijing and even expanded tensions, although it added that Washington is ready to work with China in areas where their interests do not collide, such as climate change.
Furthermore, in the light of the supply chain disruptions caused by the pandemic, the American politicians called on bringing a lot of critical production capabilities back home - especially the ones related to national security and the defence industry, and passing laws that would facilitate this process. The disruptions mainly affected the chip industry, forcing many companies in the technological and even automotive industries to reduce the planned output of their products because of a shortage of key components.
