The share of developing Asian economies in global value chain trade has doubled over twenty years, rising from 9% in 2000 to 18% in 2023. This doubling masks a fracture: certain economies, particularly China, South Korea, and Taiwan, have captured a significant share of the gains, while peripheral economies retain roles often of low value-added or limited participation. The 2026 Asian Development Bank report examines the conditions under which insertion into global value chains produces sustainable prosperity rather than volume growth without upgrading.

The Essentials

  • Asia’s share in global value chain trade doubled between 2000 and 2023, but peripheral economies remain confined to low value-added segments (ADB, Asian Development Policy Report 2026).
  • This doubling of commercial share without diffusion of gains illustrates a well-documented mechanism: productive integration does not automatically produce upgrading without structured local industrial policy.
  • American trade tensions and the recomposition of global supply chains create a window of opportunity for certain intermediate countries—Vietnam, India, Mexico—but also a risk of reproducing the same hierarchy at a smaller scale.
  • Ongoing diversification could equip intermediate Asian economies with their own productive capacities or simply displace the least profitable tasks to new sites.

Twenty Years of Growth Concentrated at the Top

The image is misleading. When we say that developing Asia now represents 18% of global value chain trade, we evoke a collective success. It is only partial.

The reality documented by the Asian Development Bank is more precise. Asia’s rise in value chains has been heterogeneous: China, South Korea, Taiwan, and Japan have built positions in high value-added segments—semiconductors, advanced electronics, fine chemicals, machine tools. Other economies remain confined to low value-added roles or insufficiently integrated. These central economies combine design, standardization, advanced production, and subcontracting, while continuing to outsource themselves. The rest of the region works for them almost as much as for Western end buyers.

Bangladesh produces clothing. Myanmar assembles simple electronic components. Cambodia manufactures shoes. These economies do participate in global value chains; they have even gained volume in doing so. Their integration into these networks varies by sector, and their level of value capture differs from one activity to another.

They remain exposed to cost competition and lack sufficient capital and technology of their own.

Economists describe this phenomenon with the term “low value-added trap”: an economy specialized in low-cost assembly tasks becomes attractive precisely for those tasks, and foreign capital has no interest in financing the upgrading that would make it less competitive in that segment.

Commercial Integration Is Not Enough

Economist Dani Rodrik has built part of his career documenting this tension. In his recent work, including Shared Prosperity in a Fractured World, Rodrik argues that development depends heavily on domestic policies and initiatives for structural transformation, rather than on international integration alone.

The argument is precise. Global value chains are hierarchies of power as much as networks of exchange. The firms that pilot them, the lead firms, have a direct interest in keeping their peripheral suppliers in segments where substitution is easy. A supplier that upgrades becomes a potential competitor. Productive cooperation has limits that market logic traces very clearly.

The logical counterpart to this diagnosis, according to Rodrik, is that upgrading requires deliberate national industrial policy: technical training, R&D investment, quality standards imposed on exporters, and international negotiation to secure the right to pursue these policies without falling under trade rules designed to open markets.

This position has serious critics. Philippe Aghion, whose work on Schumpeterian growth earned the Nobel Prize in 2025, defends a different vision: productive upgrading can occur through competition and foreign firm entry, provided the local institutional framework is solid enough to absorb and diffuse imported technologies. On this reading, the problem of peripheral Asian economies would be less the absence of industrial policy than the weakness of their institutions—property rights, judicial systems, human capital—which prevents diffusion of gains.

The ADB emphasizes that upgrading requires national capacities, institutions, skills, and coordinated policies. Trade openness alone does not guarantee upgrading and must be complemented by policies on capacities, skills, and infrastructure.

Supply Chain Recomposition Creates a Window, Not a Guarantee

Since 2018, trade tensions between the United States and China have accelerated a recomposition of global supply chains. American and European firms are actively seeking to diversify their sources of supply away from China. Vietnam has absorbed a significant share of relocated electronics production. India is attempting to position its manufacturing industry as a credible alternative for semiconductors and telecommunications equipment. Bangladesh and Cambodia are seeing new textile production lines arrive.

This recomposition is real. It creates a structural opportunity that intermediate Asian economies had not known since China’s rise to power in the 1990s. But it also reproduces, for now, the same logic: what is being relocated out of China are often the least profitable segments of the chain, those that China itself seeks to abandon to move toward advanced design and engineering.

Vietnam illustrates this risk. The country has become in fifteen years a major exporter of consumer electronics, with Samsung as its primary lead firm. A large share of design, components, and value-added remains realized outside Vietnam, notably by foreign firms including South Korean suppliers. Vietnam has become more integrated into diversified production networks, but its level of value capture varies by sector. Its role in assembly remains significant.

Supply chain recomposition could produce a new generation of economies locked into assembly or create conditions for upgrading. The outcome depends on the policy choices of the governments involved and the scope that the international commercial framework leaves for national industrial policies.

Public Policies That Make the Difference

South Korea in the 1970s-1990s remains the most cited and most instructive case. The country did not wait for the market to delegate high value-added tasks to it. It built capacities in segments where it had no immediate comparative advantage—steel, shipbuilding, then semiconductors—by accepting short-term losses and imposing technological performance requirements on its national firms. This strategy has well-documented dark sides: concentration of economic power in large family conglomerates, suppression of domestic competition, public debt mobilized to finance risky industrial bets.

But it produced genuine upgrading. South Korea today exports memory chips, cruise ships, and electric vehicle batteries. It has left the assembly trap.

Several Asian economies are today attempting to reproduce an adapted version of this model. India has launched incentive programs for production in semiconductors and electronics equipment, with substantial subsidies to attract foreign investment and build a local industry. Indonesia has imposed restrictions on the export of raw nickel to force local transformation before export, a policy that provoked a World Trade Organization dispute but effectively attracted investments in ore processing.

These initiatives show that the window created by supply chain recomposition can be seized actively. They also show its limits: India struggles to build an ecosystem of sufficiently dense local suppliers for its semiconductor ambitions to become credible in the short term. And the geographic concentration of high value-added occupations, a phenomenon also observed in digital value chains, makes diffusion toward peripheral economies structurally difficult.

Effects of Recomposition Over a Ten to Twenty-Year Horizon

The prospective question is open, and available data allow identification of two plausible trajectories without guaranteeing either.

In the first, supply chain diversification away from China produces a new generation of low value-added assembly economies. Vietnam, Bangladesh, Cambodia, possibly some Sub-Saharan African countries absorb the tasks China abandons. Western lead firms obtain logistical resilience, less dependence on a single country, without production conditions fundamentally changing. Workers in these economies gain jobs and modest income. The hierarchy of value chains reproduces itself on a geographically broader scale.

In the second, certain intermediate economies—India for its software engineers, Vietnam for its electronics, Indonesia for its processed raw materials—manage to negotiate entry into segments of increasing value-added, relying on active industrial policies and the bargaining power their market size gives them against lead firms. This trajectory requires that international trade rules leave sufficient room for national industrial policies, a condition that the return of American protectionism paradoxically makes more accessible, since the great powers themselves have abandoned the pretense of universal free trade.

The trilemma that Rodrik formalized—one cannot simultaneously have complete globalization, national sovereignty, and democracy—is replayed today in a different context from the 1990s. When Washington subsidizes its semiconductors and Brussels protects its steel, intermediate Asian economies have less reason to accept rules that would forbid them from doing the same.

The signals to watch are precise. The evolution of foreign investment in local R&D, and not merely in production, will tell whether lead firms accept sharing technological capacities or simply relocate assembly. World Trade Organization decisions on industrial policies of developing countries will draw the available margins of maneuver. And the speed at which countries like Vietnam build their own engineering capacities—technical universities, local patent filings, national firms in value-added segments—will indicate which of the two trajectories is taking hold.

The measurement of true productive wealth, beyond gross trade flows, will be decisive in evaluating these trajectories: a country that exports much but consumes its natural and human capital without renewing it accumulates an invisible productive debt that trade statistics do not show.

Conditions for Collective Upgrading

Asia will almost certainly continue to progress in volume in global trade, as its population and human capital increase. The question concerns the extent of advancement in the productive hierarchy: how many countries will benefit, beyond the region’s already advanced economies.

Three conditions emerge from documented cases. The first is public investment in technical human capital: engineers, technicians, and production managers capable of absorbing and adapting complex technologies. South Korea and Taiwan began investing massively in technical education before their industries upgraded, not after. The second is building an ecosystem of sufficiently dense local suppliers so that lead firms have an interest in deepening their commitment rather than moving production at the slightest cost shock.

The third condition, over which the debate between Rodrik and advocates of a more institutional approach remains open, is an industrial policy that directs these investments toward segments where upgrading is possible, without resorting to protectionism that isolates from international competition.

Trade openness alone does not provide these conditions. They require deliberate policies. The 2026 Asian Development Bank report shows unequal participation and gains across economies and sectors, and recommends policies adapted to different stages of integration.

The current recomposition of value chains offers a rare window. Economies that know how to seize it with active policies, and not merely with competitive labor costs, could escape the assembly trap in which their predecessors have remained locked. Those that wait to see what lead firms will deign to delegate to them will probably replay the same scenario, with new products and the same margins.
