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.
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 at a time when President-elect Donald Trump has been threatening to sharply raise tariffs on imports from China and other countries, potentially adding to simmering tensions over trade and technology.
In July 2023, China said that it would require exporters to apply for licenses to send to the US the strategically important materials such as gallium and germanium.
In August, the Chinese Commerce Ministry said it would restrict exports of antimony, which is used in a wide range of products from batteries to weapons.
China is the biggest global source of gallium and germanium, which are produced in small amounts but are needed to make computer chips for mobile phones, cars and other products, as well as solar panels and military technology.
China’s Commerce Ministry protested and said it would act to protect China’s “rights and interests” after the US side announced it was adding 140 companies to a so-called “entity list” subject to strict export controls. Nearly all are based in China, though some are Chinese-owned businesses in Japan, South Korea and Singapore.
Both governments said their respective export controls were needed for “national security.” In hitting back at the latest move by Washington to slow China's progress in developing advanced technology with potential military applications, China is tightening controls announced in July 2023.
China's government has been frustrated by US curbs on access to advanced processor chips and other technology on security grounds but was cautious in retaliating, possibly to avoid disrupting China’s fledgling developers of chips, artificial intelligence and other technology.
The US gets about half its supply of both gallium and germanium metals directly from China, according to the US Geological Survey.
China exported about 23 metric tons (25 tons) of gallium last year and produces about 600 metric tons (660 tons) of germanium per year.
