EU Tech Sovereignty Push Signals Fracture in Transatlantic Supply Chains Amid US-China Tech Rivalry

The European Commission's tech sovereignty package, bundling a Chips Act 2.0 with the Cloud and AI Development Act and open-source initiatives, marks a decisive pivot toward strategic autonomy that extends far beyond the stated goal of reducing 80% foreign dependency. While the Record coverage accurately flags tensions with the Trump administration over tariffs and Greenland, it underplays how this builds on prior EU efforts like GAIA-X and the 2023 Chips Act, which already allocated €43 billion to counter US export controls on advanced semiconductors. A critical omission is Europe's silence on ASML's lithography monopoly, which gives the bloc leverage over TSMC and global foundries yet risks alienating Dutch-US ties if Washington escalates controls. Drawing from CSIS analyses of semiconductor chokepoints and Bruegel reports on digital sovereignty, the package's open-source funding for cybersecurity could erode US vendor dominance in tools like those from Palo Alto Networks, fostering European alternatives amid XZ Utils-style supply chain attacks. This shift carries defense implications: digitalizing energy systems under the roadmap aligns with NATO resilience goals but could complicate intelligence sharing if EU clouds prioritize sovereignty over Five Eyes interoperability. Long-term, vendors like Nvidia and Arm face fragmented markets, while Beijing watches for openings to pitch alternatives, potentially accelerating a tri-polar tech order where policy, not just innovation, dictates access.
