But the restrictions also ramped up concerns that China could limit the export of other materials, particularly rare earths, of which the country is the world’s largest producer.

Rare earths are a group of 17 elements that are used in a variety of industrial, electronic, and military applications, and play a key role in electronics manufacturing.
