The U.S. and China have reached an agreement — again — to deescalate trade tensions. China is making it easier for U.S. companies crucial magnets and rare earths materials.

The U.S. and China have agreed on the framework for a trade deal, both nations say. It appears that rare earth minerals are one key part of it.

China trade deal, meant to ease tensions, faces criticism for its lack of clarity. Promises like increased rare earth exports and fewer U.S. restrictions sound promising, but the vague terms leave experts questioning how and if they’ll be enforced.
