WASHINGTON (AP) " The Interior Department says in a new report that the United States is reliant on China and other nations for the overwhelming majority of critical minerals used by the military and for manufacturing everything from smartphones to wind turbines and cars.

The report released Tuesday by the U.S. Geological Survey says the U.S. relies on foreign sources for a majority of all but two of the 23 minerals identified as critical. The minerals are produced in China, Russia, South Africa, Brazil and other countries.

Interior Secretary Ryan Zinke called the report troubling and said the reliance of imported minerals, especially by the military, poses a "very real national security risk."

Zinke urged increased U.S. production of platinum, manganese and other critical minerals, especially on federal lands.
