China's Response
First: Tariffs on coal, liquefied natural gas, crude oil, agricultural equipment, vehicles with large displacement engines, and more.
Second: New restrictions on the export of minerals used in the production of electronic devices (tungsten, tellurium, ruthenium, molybdenum, ruthenium). China has increasingly restricted mineral exports to the U.S. for the last year; in November, it banned the export of gallium, germanium, and antimony, used in everything from semiconductors to night vision goggles.
