On Monday, China imposed curbs on overseas sales of gallium and germanium, elements essential to making semiconductors, which have become a growing source of friction between the world’s top two economies. The move was widely seen as a response to the Biden administration’s ban on advanced chip sales to China, which was announced last October. “I am … concerned about new export controls recently announced by China on two critical minerals used in technologies like semiconductors,” Yellen told a meeting of business people hosted by the American Chamber of Commerce in Beijing. “I’ve been particularly troubled by punitive actions that have been taken against US firms in recent months,” Yellen added. Along with other US officials, Yellen has long signaled the Biden administration’s desire to deepen communication and lower the temperature between the world’s top two economies.
