Battery supply wars and Huawei court fights: will US tech pressure reshape Asia’s AI race?

The U.S. is pushing to reduce reliance on China for batteries, framing the shift as a strategic necessity for energy storage and industrial resilience. At the same time, Washington is expanding its South Pacific presence with new funding and a reinforced diplomatic footprint as competition with China intensifies. However, the effectiveness of the push is constrained by deep cuts to its main overseas aid agency, creating a mismatch between ambition and available leverage. In parallel, Huawei is headed to trial in the United States over its business dealings in Iran, signaling that enforcement of secondary sanctions and technology-related compliance remains a core pressure tool. Geopolitically, the cluster shows the U.S. trying to decouple critical inputs while using diplomacy, legal risk, and export-control expectations to shape partner behavior. The South Pacific effort highlights a contest for influence where island nations may resist being pulled into a binary alignment, limiting Washington’s ability to translate funding into durable political outcomes. The Huawei trial adds a deterrence layer: it warns firms that operating in sanctioned markets can become a long-running legal and reputational liability. Malaysia’s reported interest in using Huawei chips for a 2 billion ringgit sovereign AI project raises the stakes further, because it could test commitments Malaysia signed with Washington last year and complicate Kuala Lumpur’s balancing act with both major powers. Market implications cut across batteries, semiconductors, and AI infrastructure. A U.S.-China battery supply shift tends to support non-China supply chains and could lift demand for upstream materials and processing capacity, with knock-on effects for energy storage developers and industrial electrification. The Huawei and Iran case increases compliance risk premia for telecom and AI hardware vendors with exposure to sanctioned ecosystems, potentially affecting contract pricing and financing terms. On the chip side, reporting that TSMC, Intel, and Samsung are betting on ASML’s latest chipmaking tools underscores that the AI race is still bottlenecked by advanced lithography and mask supply, with EUV-related ecosystems likely to remain tight and price-supportive. What to watch next is whether Malaysia’s AI procurement proceeds with Huawei components or pivots to alternatives that better fit U.S. export-control commitments. In the U.S., the Huawei trial timeline and any court rulings that clarify the scope of permissible business with Iran-linked entities will be key for the compliance playbook across the sector. In the South Pacific, track whether Washington can sustain influence gains despite aid-agency cuts, using indicators such as port-access pledges, new agreements, and follow-on funding disbursements. For markets, monitor EUV photomask and 12-inch EUV tool capacity announcements, battery supply-chain diversification milestones, and any new enforcement actions tied to Iran-related technology dealings.

Geopolitical Implications

• 01

  Battery and AI supply-chain decoupling is becoming a broader strategic competition tool, not just an industrial policy agenda.

• 02

  Legal enforcement against firms tied to sanctioned markets (Huawei/Iran) is likely to shape partner procurement decisions and contract structures across Asia.

• 03

  Middle-power hedging (island nations, Malaysia) may dilute U.S. ability to convert funding into alignment, sustaining a fragmented regional order.

• 04

  EUV tooling and mask supply bottlenecks reinforce the leverage of a small set of advanced equipment providers, influencing bargaining power in the AI race.

Key Signals

• —Any court developments or rulings in the Huawei trial that clarify compliance boundaries for Iran-linked business.
• —Malaysia’s final procurement decision for the 2 billion ringgit sovereign AI project and whether it includes Huawei chips.
• —Evidence of sustained South Pacific port-access agreements and whether new funding offsets aid-agency cuts.
• —Announcements on 12-inch EUV photomask capacity, lead times, and ASML tool deliveries to leading foundries.
