    22nd Aug, 2023


Beijing’s active role in creating a flourishing domestic ecosystem for gallium-based chips has already benefited China’s military development.

Present stance on Gallium exports

  • China's Gallium Export Restrictions: China's new export restrictions on gallium highlight its dominance in production and intentions to wield critical minerals for geopolitical leverage.
  • Gallium's Importance: Gallium, crucial in electronics and defense sectors, holds unique properties for semiconductors in advanced systems, making supply disruptions concerning.
  • S. Response: China's gallium monopoly poses risks to global defense industries; addressing vulnerabilities through diversification and strategic partnerships is essential.

Why Gallium is important?

  • Gallium's High-Performance Applications: Gallium-based wide bandgap semiconductors power advanced military equipment, offering smaller, faster, and more efficient capabilities.
  • DARPA's Influence: Defense Advanced Research Projects Agency’s (DARPA) support led to gallium arsenide (GaAs) and gallium nitride (GaN) developments, driving advances in radar, GPS, and precision weapons.
  • Revolutionizing Defense: GaN-powered radar systems enhance threat detection, integrated into key platforms like missile defense, F-35 fighters, and naval vessels.
