China+1: Who's Really Winning —
Thailand, Vietnam or Indonesia?

As China's economy slows and capital hunts for the next factory floor, three ASEAN countries are competing for the manufacturing leaving China. There's no single winner — each holds a different weapon. Here's what the data shows.

The money is moving — but not evenly

Start with the macro, because it's the wind at everyone's back. As trade tensions reshaped supply chains, FDI into the region intensified. China alone invested about $24 billion into Southeast Asia in 2023, and its share of manufacturing FDI in the major ASEAN economies climbed from barely 10% in 2015 to more than 25% today (HSBC, McKinsey). ASEAN–China trade was set to top $984 billion in 2025.

But "money flowing into ASEAN" is a headline, not a strategy. The moment you ask where and for what, the single story splits into three very different ones.

Three countries, three weapons

The mistake operators make is treating Thailand, Vietnam and Indonesia as interchangeable "cheaper-than-China" options. They're not competing for the same work. Each has a distinct edge:

Vietnam is the established electronics export machine — $165 billion in electronics exports in 2023, and manufacturing FDI of roughly $25.35 billion in 2024, up 9.4%. Crucially, it's moving up the value chain: printed circuit boards, sensors, optical components — work that once had few alternatives outside China.

Thailand has become the region's automotive and EV hub. Chinese makers BYD, Great Wall Motor and SAIC have all set up production lines. Approved FDI applications have surged to nearly 7% of GDP — and since the start of 2025, China has accounted for close to 40% of Thailand's approved FDI, concentrated in metals, electronics and digital (much of it data centres).

Indonesia plays a different game entirely: critical minerals (it dominates global nickel), sheer domestic-market scale, and a fast-building EV battery supply chain. It's less about export assembly and more about resources and a massive internal market.

The tariff wildcard nearly leveled the field

Then came the 2025 US tariff shock. April's "Liberation Day" rates were brutal and divergent — Vietnam 46%, Thailand 36%, Indonesia 32%. But after negotiations, the October 2025 matrix landed them almost in a dead heat:

The headline rates ended up nearly identical — so on paper, the tariff stopped being a differentiator. But look closer: the transshipment penalties (40% for Indonesia, 44% for Vietnam) are explicitly designed to catch goods that are just Chinese products passing through. For operators, that changes everything: the value isn't in where you assemble, but in how much genuine local content you build. A "China+1" that's really "China through a side door" now gets punished.

So which one should you pick?

Wrong question. The data makes clear there's no universal answer — only a sector-specific one:

And the cross-cutting rule, post-tariff: build real local content. Whichever country you choose, a supply chain that's transparently just Chinese goods in transit now carries a 40%+ penalty. Genuine localization isn't just good optics — it's the difference between a 19% and a 44% tariff.

The bottom line

"Money is flowing into ASEAN" is true but useless as a decision. The operators who win the China+1 shift aren't picking a country off a headline — they're matching their specific sector to the country whose weapon fits, and structuring local content to dodge the transshipment trap. That's a precise, sector-by-sector question.
