- China is restricting exports of two niche metals — germanium and gallium — that are key to manufacture electronics and semiconductors, as the tech battle with the U.S. and Europe heats up.
- Germanium is used in fiber optic products and night-vision goggles, while gallium is a critical material for semiconductors.
- China produces 60% of the world’s germanium and 80% of gallium, according to the Critical Raw Materials Alliance, an industry body.
