China limits supply of critical minerals to Western defense companies, WSJ says

As U.S.-China trade tensions have risen, China has begun to limit the flow of critical minerals to Western defense manufacturers, which has delayed production and led many companies to sear the world for stockpiles of the minerals needed, Jon Emont, Heather Somerville, and Alistair MacDonald of The Wall Street Journal reports. China supplies approximately 90% of the world’s rare earths and also leads in production of many other minerals. Publicly traded companies in the space include BAE Systems (BAESY), Boeing (BA), GE Aerospace (GE), General Dynamics (GD), HII (HII), L3Harris Technologies (LHX), Lockheed Martin (LMT), Northrop Grumman (NOC) and RTX (RTX).
