China has announced a ban on exports to the United States of key high-tech materials with potential military applications.

China announced Tuesday it is banning exports to the United States of gallium, germanium, antimony and other key high-tech materials with potential military applications, as a general principle, lashing back at U.S. limits on semiconductor-related exports. 

The Chinese Commerce Ministry announced the move after the Washington expanded its list of Chinese companies subject to export controls on computer chip-making equipment, software and high-bandwidth memory chips. Such chips are needed for advanced applications.

The ratcheting up of trade restrictions comes as President-elect Donald Trump has been threatening to sharply raise tariffs on imports from China and other countries, potentially intensifyi

    I recognize gallium at least as a dopant material (what transforms the pure sillicon, which is an isolator, in the the n-side or the p-side of a semiconductor junction, where gallium specifically is used in light emitting junctions such as in LEDs) and a quick search showed that antimony is also a dopant.

    (For the curious, here’s the Wikipedia article)

    As you might have noticed, even my short explanation of what a dopant is actually requires people to understand to an advanced level what semiconductors actually are made of, so I can see why an AP article which is targetting the average person wouldn’t go into that specific rabit hole of explaining stuff that requires more stuff to be explained which in turn requires even more stuff to be explained and so on.

    Also, I would be surprised if there are more than a handful of journalists in the World with even the most basic understanding of how semi-conductors work.
