Vietnam’s South China Sea code push reveals AI-era infrastructure stakes
Vietnam is tying South China Sea code talks to the rules that govern subsea cables, cloud regions, and offshore energy. For AI infrastructure builders, the COC’s design could quietly set the operating baseline across Southeast Asia.

Investors often tune out South China Sea diplomacy until a ship bump or cable cut hits cashflow. Hanoi now links full DOC compliance and a faster, binding COC to UNCLOS-backed sovereign rights in Vietnam’s EEZ, including near Second Thomas Shoal. That tie-in sets de facto rules for subsea cables, cloud buildouts, and offshore power driving Southeast Asia’s AI compute.
Key Takeaways
Hanoi ties DOC/COC push to UNCLOS and Vietnam’s EEZ rights.
Clear EEZ rules de-risk cables, cloud regions, and offshore energy.
AI infra timelines hinge on these maritime guardrails.
Vietnam’s foreign ministry urged restraint around Second Thomas Shoal and “full, effective” DOC implementation consistent with UNCLOS, while pressing for a “substantive, effective” COC. By anchoring its stance in EEZ and continental shelf rights, Hanoi asserts jurisdiction over construction, maintenance, and protection of critical infrastructure—narrowing gray zones that slow permits, inflate insurance, and invite at-sea harassment.
Subsea cable consortia choose routes and landings where EEZ rules and repair access are predictable; Vietnam sites near Da Nang, Quy Nhon, and Vung Tau are being scoped to diversify chokepoints. Unclear patrol or fisheries protocols delay permits and repairs, raising latency and jeopardizing SLAs for cloud regions. Offshore gas and emerging wind are natural baseload and firming for data centers, but without de-risked governance—clear notices, incident avoidance, escorted maintenance—projects struggle to reach financial close, throttling regional compute.
What to Watch: ARF’s Manila Plan (2026–2036) backs continued DOC work and a COC push—calendars investors can map to cable landings and offshore power timetables.
