“China Plus One” has been discussed as settled fact for long enough that the underlying assumption rarely gets checked: that manufacturing capacity is moving steadily and permanently out of China into Southeast Asia, and that this trend simply continues in one direction. The 2026 data tells a more complicated story — one with real diversification, real reversals, and a structural reality that doesn’t match the simplified version of either narrative.
The Tariff Math Changed in February 2026 — And Orders Moved With It
A key structural fact often missing from the diversification narrative: the incentive to relocate production was never really about Southeast Asia being categorically cheaper — it was substantially about the tariff gap between sourcing from China versus sourcing from Vietnam or Cambodia. That gap is not fixed.
In February 2026, an additional 20% reciprocal tariff previously applied to Chinese goods was removed, replaced by a uniform 10% tariff applied across all countries. The effect was to compress the China-to-Vietnam tariff differential from roughly 15 percentage points down to under 5. Chinese trade press reported concrete, immediate effects: a factory manager in Zhongshan, Guangdong producing electric fans described a US customer relocating over a hundred sets of tooling molds back from Vietnam to China, with order volumes returning at the million-unit scale. A Jiangsu-based electronics component supplier reported that multinational clients who had previously allocated only 10–20% of orders to Chinese suppliers shifted the majority of that volume back in 2026. One export factory owner in Zhejiang, who typically kept production idle for one to two weeks around Chinese New Year, restarted operations on the third day of the holiday this year instead.
None of this means diversification has reversed wholesale — but it demonstrates that the relocation trend is sensitive to policy variables that can move faster than a factory relocation decision can be unwound, which is itself a risk factor rarely priced into “just move to Vietnam” assessments.
A Widely Misunderstood Point: Southeast Asian Tariff Rates Aren’t That Different From Each Other
A structural detail worth correcting directly: US tariff rates across most Southeast Asian sourcing destinations cluster in a fairly narrow 19–20% range — Cambodia’s rate, finalized in a binding October 2025 agreement, settled at 19%, roughly in line with Indonesia and Thailand, and only modestly below Vietnam and Bangladesh’s 20%. This means the popular framing — “relocate to Southeast Asia to substantially escape US tariffs” — doesn’t hold up as a general claim. The genuine strategic value of geographic diversification lies more in spreading single-origin policy risk and gaining access to trade agreements Southeast Asian countries hold with the EU and under RCEP, rather than meaningful US tariff arbitrage.
The Unit Economics Problem Nobody’s Spreadsheet Accounts For
A frequently cited case from Chinese manufacturing trade press illustrates a cost trap that pure wage comparisons miss. A Chinese electronics component manufacturer calculated that Vietnamese workers, at roughly RMB 3,000 monthly versus RMB 6,000 domestically, would save a 200-person factory an estimated RMB 7.2 million annually in labor costs alone. Six months after relocating equipment and staffing a facility in Bac Ninh province, the calculation didn’t hold: Vietnamese workers on the same production line were producing at roughly 60–70% of the daily output of their Chinese counterparts — 700 units per day versus 1,000 — meaning fixed costs per unit actually rose despite the lower nominal wage, once productivity was factored in properly.
Vietnam’s Power Grid Is a Real, Quantified Constraint
Electricity reliability in northern Vietnam’s industrial zones has been a persistent, measurable problem rather than an occasional inconvenience. Power shortfalls in the region have run around 30% for extended periods. Blackout days increased roughly 35% year-over-year in 2023, with direct manufacturing losses estimated at $1.4 billion that year. A 2025 drought along the Mekong left hydroelectric capacity severely constrained. In response, Vietnam’s Ministry of Industry and Trade set explicit reduction targets for 2026: electricity consumption must fall by at least 3% for the year overall, rising to a 10% reduction target during the April–July dry season peak. Reporting indicates Foxconn’s local facilities were specifically directed to cut electricity usage by 30–50%. For any buyer treating a Vietnam relocation as a straightforward cost swap, this is a total-cost-of-ownership variable that a wage comparison alone won’t surface.
Roughly 40% of Chinese-Invested Vietnam Factories Are Reportedly Losing Money
A survey report circulated in April 2026 found that approximately 40% of Chinese-invested manufacturing enterprises operating in Vietnam were running at a loss. This single data point should be read as directional rather than a precise industry-wide figure, but it’s consistent with the productivity and power-reliability issues described above, and it complicates the assumption that relocating to Vietnam is a straightforward margin improvement.
The Next Layer: “Vietnam Plus One”
A newer pattern emerging through 2025–2026: as US scrutiny of Vietnam-origin goods intensifies — specifically around transshipment and rules-of-origin verification for goods with substantial Chinese content — combined with rising wages and land costs within Vietnam itself, companies already established there have begun evaluating a second backup location. Cambodia has been a notable beneficiary: 2025 foreign direct investment reached $5.2 billion, up 18.2% year-over-year, with roughly 70% (about $3.76 billion) originating from Chinese capital, and manufacturing-sector investment growth around 50%. Companies moving into Cambodia in this wave reportedly tend to have more export experience and supply chain management maturity than the earlier generation that moved into Vietnam — a sign the destination is absorbing more sophisticated operations, not just overflow capacity.
The Overlooked Point: Much of the “Relocation” Is Chinese Capital, Not Foreign Buyers Abandoning China
Perhaps the most significant reframing the 2026 data supports: greenfield manufacturing investment from China into ASEAN countries averaged roughly $12.9 billion annually between 2020 and 2023 — nearly double the $6.1 billion annual average of the three years prior. This complicates the framing of “China Plus One” as foreign buyers systematically abandoning Chinese suppliers for Southeast Asian ones. A substantial share of the capacity build-out in Vietnam, Cambodia, and elsewhere in the region is Chinese manufacturers and Chinese capital themselves establishing production closer to end markets or expanding regional footprint — which is a different phenomenon from Western brands independently qualifying non-Chinese suppliers, even though both get described under the same “China Plus One” label.
What This Adds Up To
The honest summary of 2026’s data is neither “China Plus One has failed” nor “manufacturing has permanently left China.” Both narratives oversimplify a more fragmented reality: genuine diversification is happening, particularly in electronics and textiles, and particularly for buyers managing single-origin policy risk rather than chasing the lowest possible unit cost. At the same time, the cost advantage of relocation is frequently smaller than a wage-only comparison suggests once productivity, power reliability, and total cost of ownership are factored in — and the relocation trend itself is sensitive enough to shifting tariff policy that a decision made under 2025’s tariff structure can look different by mid-2026. Southeast Asia is not a single, uniform “next China” — Vietnam, Cambodia, Malaysia, and Indonesia each carry distinct and evolving tradeoffs, and much of the region’s new capacity is itself Chinese-built.
