China+1 for electronics: Vietnam, Thailand or Malaysia

Electronics led the China + 1 wave: from Samsung and Intel to Chinese component suppliers, hundreds of plants have shifted part of their chains to Southeast Asia. But Vietnam, Thailand or Malaysia — where should an electronics factory go? The three have very different “personalities”: Vietnam leads on scale and speed, Thailand on automotive electronics and infrastructure, Malaysia on semiconductors and engineering talent. This article scores the three on seven electronics-specific criteria — because siting an electronics plant is nothing like siting a garment factory.

Criteria 1–2: clusters and engineering talent

(1) Electronics cluster depth. Vietnam has the largest electronics cluster of the three by export scale — Bac Ninh, Bac Giang and Thai Nguyen host hundreds of component suppliers, from PCBs to engineering plastics. But most are FDI; domestic firms’ participation in the value chain remains thin. Malaysia has the oldest semiconductor cluster (Penang — the “Silicon Valley of the East” since the 1970s), strong in chip packaging/testing (OSAT). Thailand leads in automotive electronics (Eastern Economic Corridor). Scores: Vietnam 8/10 (assembly + components), Malaysia 8/10 (semiconductors), Thailand 7/10 (auto electronics).

(2) Technical workforce. Electronics needs engineers and technicians at scale. Vietnam: abundant young labour, low cost, but short of experienced engineers for higher-end steps (design, semiconductor testing). Malaysia: the best English-speaking technical workforce, deep semiconductor experience, but higher cost and shortages of general workers. Thailand: balanced — decent engineering, mid-range cost. Scores: Malaysia 8/10, Thailand 7/10, Vietnam 7/10 (strong on numbers, weak on depth).

Criteria 3–4: cost and incentives

(3) All-in cost. Vietnam: cheapest labour, northern industrial rents rising fast but still competitive; cheap power but dry-season shortage risk in the north has materialised before. Thailand: 15–25% costlier but stable power and good infrastructure. Malaysia: costliest of the three, partly offset by higher productivity. Scores: Vietnam 8/10, Thailand 7/10, Malaysia 6/10.

(4) High-tech investment incentives. All three court electronics/semiconductors. Vietnam: CIT incentives for high-tech projects under Investment Law 143/2025 (tax holidays + land-rent preferences). Thailand: BOI tiers incentives by technology level (higher tech, longer holidays). Malaysia: MIDA plus dedicated semiconductor packages (New Industrial Master Plan). Scores: 7/10 each — comparable on paper; the difference is in execution (Thailand/Malaysia more predictable; Vietnam attractive on paper but implementation varies by locality).

Criteria 5–7: markets, risk and speed

(5) Proximity to Chinese supply chains. Most electronic components still come from China — Vietnam shares a land border, with 1–2 day trucking; Thailand and Malaysia need sea/air freight, slower and pricier. Under the “Chinese components + Southeast Asian assembly” model, distance is a hard cost. Scores: Vietnam 9/10, Thailand 6/10, Malaysia 6/10.

(6) US tariff risk. Vietnamese electronics exports to the US have faced probes (wooden cabinets and solar panels set related precedents). Malaysian semiconductor exports to the US are also watched. Thailand is less targeted but not immune. Scores: Thailand 7/10, Malaysia 6/10, Vietnam 6/10.

(7) Speed to production. Vietnam: abundant ready-built factories, fast IRC — producing in 3–6 months is realistic. Thailand: stable BOI approvals but suitable park land takes longer to find. Malaysia: good procedures but a shortage of new park land in Penang (high occupancy). Scores: Vietnam 8/10, Thailand 7/10, Malaysia 6/10.

Verdict: choose by the plant’s “role”

Totals (out of 70): Vietnam 54, Thailand 48, Malaysia 47 — but the right answer depends on the plant’s role: consumer-electronics assembly (phones, appliances) → Vietnam (ready clusters, cheap labour, near China). Semiconductors/chip packaging → Malaysia (the Penang ecosystem can’t be replicated short-term). Automotive electronics → Thailand (EEC auto cluster; customers are carmakers sited in Thailand). The common two-leg play: assembly in Vietnam + R&D/chip packaging in Malaysia — split by value-chain step instead of picking one country for everything.

Checklist: siting an electronics plant

1. Define the step: assembly, component manufacturing, or semiconductors — each step has a different “home”. 2. Assess the supply cluster: enough tier-1/2 suppliers within 100km? 3. Check talent: how many engineers? Hired from where? 4. Model 5-year cost: labour + land + power + component logistics from China. 5. Review incentives: what high-tech incentives per country, and how they’re actually administered. 6. Assess US tariff risk: investigation precedents in your product? 7. Verify power: especially northern Vietnam — the park’s supply commitments. 8. Speed: what’s the production deadline? Which country meets it? 9. Consider splitting steps across two countries at sufficient scale. 10. Refresh annually — incentive and tariff maps move fast. 11. Benchmark turnover: electronics parks in all three countries run 15–25% annual operator turnover — model recruitment as a continuous cost, not a one-off project.

Three electronics-specific risks and how to dodge them

Risk 1: component-chain “snaps” in geopolitical stress. Electronics depends deeply on Chinese components (chips, displays, batteries). If the chain breaks, plants in Vietnam, Thailand and Malaysia all freeze alike — dodge: keep two sources for critical components (one Chinese, one Taiwanese/Korean) and hold 4–6 weeks of safety stock for parts that can’t be substituted quickly. Risk 2: chip-price swings and inventory cycles. Electronics runs 2–3-year glut-shortage cycles — a new plant ramping at the top of an inventory glut loses money in year one. Dodge: sign long-term offtake contracts with customers before sizing the plant; never build to demand forecasts. Risk 3: ESG and carbon demands from Western customers. Apple, Samsung and other majors require suppliers to report carbon and use renewable energy — a Vietnamese plant (still coal-heavy grid) is disadvantaged versus Malaysia/Thailand without rooftop solar + renewable-energy certificates designed in from day one. General rule: in electronics, picking the country is only 50% of the decision — the other 50% is designing a supply chain and customer contracts sturdy enough to survive one full downturn cycle.

The talent pipeline — building what the country doesn’t have

No Southeast Asian country hands you a ready-made electronics engineering workforce — you build it. Vietnam: partner with technical universities in Bac Ninh/Hanoi for customised training pipelines (Samsung’s supplier academy model works — copy it); budget 6–12 months to bring fresh graduates to full productivity. Malaysia: poach from the Penang semiconductor ecosystem — expensive but instant; retention requires regional pay benchmarking, not local. Thailand: the EEC’s skills-development programmes co-fund training — apply early, the quotas go fast. Cross-cutting: for Chinese investors, the scarcest resource is bilingual (Chinese–local language) middle management — start recruiting before the plant is built, because a factory without bilingual supervisors is a factory where nothing gets communicated. Treat workforce development as capex with a 2-year payback, not as an HR afterthought — the plants that ramp fastest are the ones that hired their first 50 technicians a year before opening. Visa planning belongs in the same budget: Chinese engineers on technical-support rotations need work permits and residence cards in each country, and the lead times differ — Vietnam’s process is the fastest of the three, Malaysia’s the most documentation-heavy. Start the first permit applications the week the site lease is signed, not the week the engineers are due to fly.
