DECOUPLING: China just stopped exporting two minerals the world’s chipmakers need.

China produces about 80% of the world’s gallium and about 60% of germanium, according to the Critical Raw Materials Alliance, but it didn’t sell any of the elements on international markets last month, Chinese customs data released on Wednesday showed. In July, the country exported 5.15 metric tons of forged gallium products and 8.1 metric tons of forged germanium products.

When asked about the lack of exports last month, He Yadong, a spokesperson from China’s commerce ministry told a press briefing Thursday that the department had received applications from companies to export the two materials. Some applications had been approved, he said, without elaborating.

The curbs are indicative of China’s apparent willingness to retaliate against US export controls, despite concerns about economic growth, as a tech war simmers.

Nobody ever said weaning ourselves off the CCP would be easy.
