Great-Power Rivalry Puts the Squeeze on Southeast Asia's Supply Chains

Southeast Asia's strategic supply chains now sit under direct pressure from both Washington and Beijing, according to an analysis published by the East Asia Forum under the headline "Great powers squeeze Southeast Asia's strategic supply chains."

The framing is blunt. Two large economies are competing for control over the flows of strategic goods that pass through the region. Southeast Asian states are caught between them. That is the core of the story, and it is worth taking apart slowly.

What does this change for the region?

It changes the bargaining position. Countries such as Vietnam, Thailand, Malaysia and Indonesia have spent two decades selling themselves as neutral manufacturing ground. Firms could locate a factory there, source inputs from China, and sell finished goods into Western markets. That model worked because both sides of the geopolitical divide tolerated it.

Now each side wants more. The squeeze described in the East Asia Forum analysis implies pressure from two directions at once. One great power wants supply chains decoupled from its rival. The other wants them locked in. A regional government cannot fully satisfy both.

How does the mechanism work?

The mechanism runs through trade rules and market access. When a great power restricts what its firms may buy, or what foreign firms may sell into its market, it changes the economics of every factory in the region.

Consider the decision chain:

• A multinational chooses where to build capacity.
• It weighs tariffs, export controls and subsidy regimes.
• It picks a location that satisfies the rules of the market it most needs to reach.
• Southeast Asian governments then compete to become that location, while avoiding penalties from the excluded power.

Each step narrows the room for manoeuvre. The squeeze tightens when both powers apply pressure in the same period, which is what the analysis suggests is happening.

Why does neutrality get harder?

Neutrality gets harder because strategic goods are the focal point. Ordinary consumer trade can flow almost anywhere. Strategic categories — advanced components, critical minerals, defence-relevant technology — attract rules that follow the goods, not the flag of the factory.

A Southeast Asian plant assembling strategic inputs may find its products barred from one market because of the origin of its components, and courted by another for the same reason. The factory owner cannot fix this by relocating. The constraint sits in the trade relationship between the two great powers, not in any single country's policy.

The analysis title itself carries the verdict: the region is being squeezed, not merely courted. Squeezing implies deliberate pressure from both sides, and reduced freedom for the party in the middle.

What should readers watch next?

Watch the individual deals. When a Southeast Asian government signs a trade arrangement with one power, watch whether the other responds with a restriction. That pattern — concession from one side, penalty from the other — is the practical shape of the squeeze.

Also watch investment announcements. Firms voting with capital reveal the real direction of supply chains faster than official statements do. The East Asia Forum analysis points to a region whose strategic role is being decided largely by others, and the evidence will accumulate in customs data and factory openings, not in communiqués.

The underlying question for the region is simple. Can Southeast Asia stay a hub for both powers at once, or must it eventually choose? The analysis suggests the room to avoid that choice is shrinking.
