Overview

The United States and the Republic of Korea (ROK) are deepening cooperation across artificial intelligence (AI), quantum technology, and 6G—aimed at strengthening allied tech leadership and constraining China’s strategic options. Recent workshops and joint statements underscore a widening agenda: AI export promotion, quantum industrial security, and open, secure 6G stacks.

What’s New & Why It Matters

  • AI acceleration: Washington has elevated AI export promotion and allied market access as policy priorities in Korea, framing AI as a core export and security domain.
  • Quantum coordination: The U.S., ROK, and Japan launched trilateral quantum security workshops to align standards, safeguard IP, and de‑risk supply chains.
  • 6G roadmap: Seoul has designated 6G and quantum as national priorities and is pushing public‑private testbeds to lead the post‑5G era.

How the U.S. Uses Allies to Counter China

  1. Standards & export controls: Aligning allied 6G, AI, and quantum standards while tightening controls on sensitive tools and data narrows Beijing’s substitution paths.
  2. Allied R&D scale: U.S.–ROK R&D consortia pool NIST/KRISS, lab‑to‑lab ties, and industry programs (e.g., Open RAN, quantum communications) to accelerate time‑to‑market.
  3. Industrial security: Trilateral workshops (U.S.–ROK–Japan) share best practices on IP protection and secure manufacturing, aiming to keep high‑value nodes in allied jurisdictions.
  4. Market leverage: U.S. cloud/semiconductor leadership plus Korea’s memory, foundry, and telecom equipment strengths amplify bargaining power in any tech‑trade negotiation with China.

First Island Chain: Geoeconomic Reinforcement

Closer U.S.–ROK tech ties complement defense posture along the First Island Chain (Japan–Korea–Taiwan–Philippines). Coordinated spectrum policy, secure subsea/backbone upgrades, and 6G open networks help harden digital infrastructure while diversifying away from China‑centric equipment. Quantum key distribution (QKD) pilots and post‑quantum cryptography roadmaps aim to secure cross‑border data flows.

Data Points

  • Quantum coordination: U.S.–ROK joint statements and programs connect NIST with KRISS and create industry bridges via QED‑C and KQIA.
  • Trilateral workshops (Sep 2025): The U.S., ROK, and Japan held quantum industrial security workshops in Seoul and Tokyo to align safeguards across the ecosystem.
  • Korea AI compute build‑out (Feb 2025): Korea announced plans to secure roughly 10,000 GPUs for a national AI center in 2025, highlighting public‑private mobilization.
  • Private‑sector linkages (Feb 2025 & Oct 2025): OpenAI–Kakao collaboration and NVIDIA’s APEC presence in Seoul signal deepening AI hardware/services ties with Samsung and SK Hynix.

Global Supply Chain Impact

Semiconductors: Allied alignment keeps advanced logic, memory, and packaging anchored in the U.S.–ROK–Japan corridor, with guardrails on tool exports to China. Telecom: 6G pilots and Open RAN favor trusted vendors, shifting baseband/radio procurement away from PRC suppliers. Quantum: Joint roadmaps for quantum sensors, networks, and secure standards reduce fragmentation and lock in allied IP. Logistics: AI‑enabled demand forecasting a...

U.S. Outlook

  • Investment: Tracked announcements imply tens of billions (public + private) into AI compute, memory, packaging, and telecom modernization through 2027.
  • Jobs: Semiconductor expansions (fabs, advanced packaging) and cloud build‑outs add high‑skilled roles across Arizona–Texas and Korea’s chip clusters.
  • Growth: A credible U.S.–ROK–Japan tech bloc could add 0.2–0.4 pp to U.S. real GDP in 2026–2028 via exports, capex, and services subscriptions.
