China's Export Curbs on Gallium and Germanium: Implications for Global Microchip Industry

China is set to impose export restrictions on gallium and germanium, key materials used in the semiconductor industry, as part of the ongoing chip war with the US. These materials are crucial for chip production and have military applications. China currently dominates the global supply chain for gallium and germanium. The move comes in response to export controls imposed by the US and other countries on advanced microprocessor technology. Concerns are rising over "resource nationalism" as governments hoard critical materials to exert influence. While the impact of these restrictions may be limited in the long-term, it highlights the need for diversifying supply chains and reducing reliance on China for raw materials and finished products.
