China has announced a ban on the export of gallium, germanium, and antimony to the United States, marking a significant escalation in the ongoing tech and trade dispute between the two countries. The move is seen as a response to U.S. restrictions on advanced semiconductor technologies aimed at curbing China’s tech ambitions.

Gallium and germanium are critical materials used in the production of semiconductors, solar panels, and military applications. Their export ban is expected to disrupt global supply chains and heighten tensions in the already strained US-China relationship.

Chinese officials stated that the ban is intended to safeguard national security and retaliate against what they described as “unilateral and discriminatory measures” imposed by the U.S.

This development highlights the intensifying tech rivalry between the world’s two largest economies, with potential implications for industries reliant on these rare metals.
