WASHINGTON : The United States"firmly" opposes export controls announced by China on gallium and germanium, metals needed to produce semiconductors and other electronics, a U.S. Commerce Department spokesperson said on Wednesday, adding that Washington will consult its partners and allies to address the issue.
Germanium is used in high-speed computer chips, plastics and in military applications such as night-vision devices, as well as satellite imagery sensors.

China's move, which its commerce ministry said was to protect national security, was seen by economic analysts as a response to escalating efforts by Washington to curb China's technological advances.
