Rare Earth Export Controls - China's new rare earth export controls require case-by-case approval for anyone using rare earths to develop advanced semiconductors (defined as 14nm-and-below) [1] - These export controls effectively give China veto power over the entire advanced semiconductor supply chain, as rare earths are used at critical steps [2] - The export controls are extraterritorial, requiring foreign entities to obtain Chinese export licenses for re-exporting products containing 0.1% or more of Chinese rare earth materials [2] Geopolitical Implications - China is mirroring the US semiconductor export controls with its own comprehensive extraterritorial control regime, but with rare earths [3]
