A senior procurement executive at a German automotive supplier was asked in late 2024 to summarize, in one sentence, how her company's sourcing footprint had changed in five years. Her answer: "We used to have a China strategy. Now we have a Vietnam strategy, a Malaysia strategy, an Indonesia strategy, a Thailand strategy, and a smaller China strategy, and we coordinate them weekly." She was not describing a hedge. She was describing a structural reorganization of where industrial production happens in Asia, and her company is one of several thousand making the same set of decisions in parallel.
The narrative of "China Plus One" has been around since roughly 2017 and was, for most of that period, more talked about than executed. The trade tensions of the late 2010s, the pandemic-era logistics shocks of 2020 to 2022, and the geopolitical positioning of 2023 to 2025 have together moved the conversation past the strategy phase. The capital is now committed. The facilities are being built. The supplier qualifications are being completed. The supply chains that will define the next industrial decade are being drawn in Southeast Asia right now, and the lines being drawn this year will be very difficult to redraw in 2030.
What is interesting about this moment is not the macro story (everyone has read that one). It is the specific operational reality of which countries are capturing which categories, why the differentiation is happening the way it is, and what an operator should understand about the timing window that is now closing.
- Foreign direct investment into ASEAN reached $230 billion in 2023, surpassing China for the first time since 2013 (UNCTAD World Investment Report).
- Vietnam's manufacturing exports grew 14 percent annually between 2018 and 2024; Malaysia's electronics exports grew 11 percent over the same period (ASEAN Statistical Yearbook).
- Roughly 40 percent of US importers and 32 percent of European importers report having shifted at least part of their sourcing from China to Southeast Asia in the past three years (HSBC Trade Confidence Index, 2024).
- Combined ASEAN GDP is projected to reach $5.2 trillion by 2030, making it the fourth-largest economic bloc globally.
Why each country is winning what it is winning
The casual reading of the China Plus One narrative imagines Southeast Asia as a homogeneous alternative. The operating reality is the opposite. Each country in the region has positioned itself for specific categories, based on a combination of cost structure, labor pool, infrastructure, regulatory regime, and existing industrial base. Companies that treat the region as a single decision are missing the strategic structure underneath.
Vietnam has captured the electronics and apparel categories most decisively. Samsung produces more than half its global mobile devices in Vietnam. Apple has moved AirPods, iPads, and Watch assembly meaningfully into Vietnamese facilities. Foxconn, Pegatron, and Luxshare have all built at scale. The combination that produced this outcome was specific: very low labor cost relative to China, a stable government willing to grant tax incentives, deepwater port access in Hai Phong, and a young workforce of roughly 100 million people willing to enter manufacturing employment. The vulnerability is in mid-skill engineering talent and in power infrastructure, both of which are being addressed but neither of which is solved.
Malaysia has captured the higher-end semiconductor backend and electronics manufacturing services categories. Penang has become the world's most concentrated cluster for chip packaging, with Intel, AMD, Infineon, Bosch, and Lam Research all operating at scale. The advantage here is the mature engineering talent pool, a regulatory regime that has supported the industry continuously for decades, and physical infrastructure that has been built around the semiconductor sector. Malaysia is not competing on cost. It is competing on capability, and the capability is genuinely difficult to replicate.
Indonesia has captured nickel processing and the EV battery value chain, driven by its position as the world's largest nickel producer and a deliberate government policy to capture downstream value. CATL, LG Energy Solution, and Hyundai have all committed multi-billion-dollar investments. The strategy is explicit: use the resource leverage to force foreign capital to invest in domestic processing rather than just extraction. It is working, and Indonesia is on track to be one of the largest EV battery producers globally by 2028.
Thailand has retained its position as the automotive manufacturing hub of the region, with Toyota, Honda, and the Chinese EV makers (BYD, Great Wall, MG) all expanding production. The Eastern Economic Corridor has been a deliberate piece of industrial policy, and it has produced the infrastructure backbone that automotive supply chains require. Thailand's challenge is in transitioning from internal combustion to EV production fast enough to retain share.
The Philippines has positioned itself in business process outsourcing at scale and is now building light manufacturing capability, particularly in electronics assembly and food processing. The English-language advantage and educated workforce produce a different value proposition than the rest of the region.
What the region has that China still has more of
It is worth being honest about what Southeast Asia does not yet have. The region is not a replacement for China across every dimension. China retains decisive advantages in several categories that take a decade or more to replicate.
The supplier ecosystem depth in China is unmatched. A manufacturer in Shenzhen can source any electronic component within a 50-kilometer radius, often from multiple suppliers. The equivalent supply chain in Vietnam or Malaysia is significantly thinner. This matters most for products with complex bills of materials or rapidly changing designs, where the time cost of cross-border sourcing is material.
The engineering and operations talent at scale is still concentrated in China. A complex manufacturing line can be staffed in Shenzhen with engineers from any major university in the country. Vietnam and Indonesia are building this capacity, but it is a fifteen-year project, not a five-year one. The talent constraint is the most underestimated factor in companies' transition plans.
The infrastructure backbone in China (ports, highways, rail, power) is still better than anywhere else in the developing world. Southeast Asia is investing, but the absolute gap is substantial. A container moves through Shanghai port faster, more reliably, and at lower cost than through Ho Chi Minh City, and this gap will close over the next decade rather than close immediately.
What Southeast Asia has is the political acceptability for western buyers, the trajectory of capability building that compounds, and the scale to absorb the share that China is losing. The combination is enough. The region does not need to match China across every dimension. It needs to be good enough across the dimensions that matter, and to be politically deployable, which it is.
The choice is not between China and Southeast Asia. It is between staying with the supply chain that worked in 2018 and building the one that will work in 2030.
The window that is closing
The decisions being made now have an asymmetric quality. The position you can build in Vietnam, Malaysia, Indonesia, or Thailand in 2026 will not be available on the same terms in 2030. The tax incentives are being adjusted as the countries gain leverage. The land prices in industrial zones are rising. The skilled labor pool is being claimed by early movers. The supplier relationships are forming around the companies that arrived first.
The operators who moved in 2018 to 2022 have visible advantages today: lower-cost facilities, established supplier networks, trained local management, regulatory familiarity. The operators who are moving now in 2025 to 2027 will have similar advantages by 2030. The operators who wait until 2028 or 2029 will find themselves entering a market where the favorable terms have been claimed and the operating conditions, while still good, are no longer differentiated.
This is the closing window argument. It is not that the region will stop being a good place to manufacture. It is that the position-building advantages available now are not durable. The companies treating this as a five-year strategic question rather than a two-year operating decision are making the structural mistake that will define their next decade.
What the operator does with this
Three diagnostics help an operator orient.
First, category specificity. The decision is not "do we manufacture in Southeast Asia." It is "for which categories, in which country, against which capability we need to build." A company in semiconductors should be looking at Malaysia. A company in EV batteries should be looking at Indonesia. A company in automotive should be looking at Thailand. A company in apparel or electronics assembly should be looking at Vietnam. The country choice is downstream of the category, and conflating them produces poor decisions.
Second, the supplier qualification timeline. Building a qualified supplier base in a new region takes 18 to 36 months at minimum. Companies that have begun this work are already capturing value. Companies that have not are looking at production starts in 2028 or 2029 from decisions taken today, which is past the window where the operating advantage is still meaningfully differentiated.
Third, the regional management capability. The companies that operate well in Southeast Asia have invested in regional management with deep local knowledge. The companies that try to manage from headquarters or through expatriate placements have struggled. The right model is a regional leadership team with multi-country authority, deep cultural fluency, and direct CEO access.
The supply chains of 2030 are being drawn now, in the contracts, the facility commitments, and the supplier qualifications happening this year. The companies that read the moment correctly will spend the next decade operating from positions they took in 2026. The companies that are still studying the question will be building from positions taken by their competitors.
