Asia's Next Growth Story: How Regional Markets are Redefining Trade

For decades, one of the simplest ways to describe Asian trade was to imagine factories in Asia producing goods for consumers somewhere else, particularly in North America and Europe. That description is still partly true, but it is becoming incomplete. Asia is increasingly becoming not only the world's manufacturing centre but also one of its most important sources of demand, investment and regional trade.

The Regional Comprehensive Economic Partnership, or RCEP, is an important part of this story. The 15-member agreement brings together the ten ASEAN countries with China, Japan, South Korea, Australia and New Zealand. It began entering into force in 2022 and created the world's largest free trade area by economic coverage. But the more interesting question is not simply whether RCEP is large. It is whether the agreement is actually changing where Asian economies trade, how supply chains are organised and how dependent businesses are on markets outside the region.

The latest numbers provide an interesting but more complicated answer than the headline figures suggest. According to the Asia Global Institute's RCEP Trade Tracker, trade among RCEP members reached about US$6.039 trillion in 2025. That sounds like an enormous post-RCEP expansion, but the comparison needs to be made carefully. Intra-RCEP trade was already about US$6.033 trillion in 2022, the year the agreement began taking effect. It then fell to about US$5.505 trillion in 2023 before recovering. The stronger long-term comparison is with 2019, before both the pandemic and RCEP's implementation. Against that benchmark, 2025 intra-RCEP trade was about 34% higher than the US$4.500 trillion recorded in 2019. 

This distinction matters because it prevents us from turning correlation into causation. It would be too easy to say that RCEP created US$6 trillion of regional trade. The data do not prove that. The increase also reflects China's enormous manufacturing base, the recovery of global trade after the pandemic, changing supply chains, rising Asian consumption and investment flows across the region. RCEP may be supporting these developments by reducing tariffs and creating common rules of origin, but it is operating alongside several other powerful economic forces.

Even so, the scale of the region is difficult to ignore. AMRO's latest analysis shows that the RCEP region accounted for around 28% of global GDP in 2025, up from roughly 20% in 1990. The region represents around 30% of the world's population and approximately 30% of global trade. Its economic weight is now comparable with North America's share of global GDP and significantly larger than the euro area's. 

The more important change, however, may be happening on the demand side. AMRO estimates that ASEAN+3, consisting of the ten ASEAN economies plus China, Japan and South Korea, accounted for about 20% of global final demand in 2000. By 2024, its share had risen to approximately 27.5%, making ASEAN+3 the world's largest source of final demand. 

This is a major change in the economic geography of Asia. For years, companies could think about Asia mainly as a production location. Increasingly, companies also have to think about Asia as a market. A factory in Vietnam may source components from China, Malaysia or Thailand, assemble products locally and sell some of them to consumers in neighbouring Asian economies. A Japanese company may diversify production across Southeast Asia while still serving Asian consumers. These are not isolated examples. They are part of a broader regional production and demand network.

China remains the central trading hub within this network, but its role is changing rather than simply expanding in every direction. Analysis from the Asia Global Institute shows that China's exports to RCEP partners increased by about 3.6% in 2024 after declining 8.5% in 2023. The published analysis refers to approximately US$2.76 trillion of exports to RCEP partners in the first three quarters of 2024. Because the source has a unit inconsistency in its published wording, this figure should be treated cautiously rather than presented as an independently verified headline statistic. China's official customs data provide a more reliable benchmark: China's total trade with RCEP partners reached RMB 9.63 trillion during the first three quarters of 2024. 

The country-level pattern is more interesting than the aggregate number. Chinese exports to Vietnam increased by 12.7% in 2024, while exports to Laos and Cambodia increased by 17.7% and 14.6%, respectively. By comparison, exports to Singapore and Thailand grew by around 6%, while exports to Indonesia rose only 0.3%. Chinese exports to Japan declined by about 1.9% in 2024 after falling 5.1% in 2023.

This contrast tells us something important about the next phase of Asian trade. The fastest-growing connections are not necessarily between the region's largest and most mature economies. Some of the strongest growth is occurring in economies such as Vietnam, Cambodia and Laos, where industrial capacity, infrastructure and participation in regional supply chains are still developing.

Vietnam is particularly important in this respect. Its increasing role in Asian supply chains means that trade with China does not necessarily represent simple dependence on Chinese consumption. Chinese machinery, intermediate goods and components can support Vietnamese manufacturing that subsequently exports to other markets. Regional trade can therefore represent a production relationship rather than simply a relationship between a seller and a final consumer.

But there is another side to the story. The three largest Northeast Asian economies within RCEP, China, Japan and South Korea, have not experienced uniformly stronger bilateral trade since the agreement took effect. The Asia Global Institute reports that during the three years following RCEP's ratification, Japan's exports to China and South Korea fell by 13.7% and 14.6%, respectively. Japanese imports from China and South Korea also declined by 6.3% and 11.0%. 

That is an important warning against describing RCEP as an automatic engine of integration. If tariff reductions alone were sufficient to increase trade, we would expect the largest established economies to show stronger bilateral expansion. Instead, the evidence suggests that economic conditions, industrial competition and supply-chain strategies can sometimes be more powerful than a trade agreement.

Japan's behaviour illustrates this particularly well. Rather than simply becoming more dependent on China, Japanese companies have increasingly diversified supply chains toward countries such as Vietnam and Malaysia. The result is not necessarily less Asian integration. It may actually mean different Asian integration. Production can move from one regional economy to another without leaving the wider Asian supply-chain network.

ASEAN provides another useful comparison. Intra-ASEAN trade declined by about 13.3% in 2023 before rebounding by approximately 7% in 2024. The recovery is consistent with an improvement in regional trade conditions, but it should not automatically be interpreted as proof that RCEP caused the increase. ASEAN has its own economic integration process, domestic demand cycles, investment trends and trade agreements operating alongside RCEP. 

There is another figure that makes the story even more interesting. Trade between RCEP members and countries outside the bloc also continued to grow. Analysis of the region shows that non-RCEP trade reached roughly US$3.4 trillion in 2024, increasing by about 5%. This means RCEP economies were not simply replacing global trade with regional trade. They were strengthening regional connections while continuing to trade heavily with non-member economies.

This may be one of the most important findings in the entire story. Regionalisation does not necessarily mean deglobalisation. An Asian company can simultaneously become more integrated with neighbouring Asian economies and remain deeply connected to the United States, Europe and other global markets. RCEP may therefore be better understood as an additional layer of economic integration rather than a wall separating Asia from the rest of the world.

The structure of intra-RCEP trade also provides evidence of changing industrial competition. The latest RCEP Trade Tracker reports particularly strong growth in several strategic sectors between 2022 and 2025. China's exports to the RCEP region increased by 362.6% for vehicles, 193.3% for electric vehicles, 41.5% for lithium-ion batteries and 23.6% for semiconductors over that period. By 2025, China's share of the RCEP market reached about 97% for electric vehicles and 94% for lithium-ion batteries, while its share of total vehicles reached about 33.8%.

These numbers reveal another layer of the RCEP story. Regional integration is not simply about more goods crossing borders. It is also about which countries are gaining competitive positions in future industries. China's strength in electric vehicles, batteries and related manufacturing gives it an important position in the region's industrial transition. At the same time, Southeast Asian economies are competing to attract factories, investment and technology as companies diversify their production networks.

This creates both opportunities and risks for smaller economies. On one hand, countries such as Vietnam, Cambodia and Laos can benefit from investment, employment, exports and technology transfer. On the other hand, becoming part of a regional supply chain does not automatically mean moving into high-value activities. An economy can increase exports while remaining dependent on imported machinery, components or technology. The real test of regional integration is therefore not only whether trade increases, but whether countries develop stronger domestic productive capabilities.

The same issue applies to businesses. RCEP can make regional sourcing easier, but companies still have to consider logistics, infrastructure, labour costs, energy prices, political risks, exchange rates and technological capabilities. A tariff advantage alone does not make a country the best production location. The strongest businesses are likely to be those that use regional agreements as one part of a broader supply-chain strategy rather than treating them as a substitute for competitiveness.

There is also an important limitation in the headline US$6.039 trillion figure. The share of intra-RCEP trade in members' total global trade remained remarkably stable at around 59% between 2019 and 2025, moving from 58.8% in 2019 to 58.6% in 2025. In other words, intra-regional trade has become much larger in absolute value compared with 2019, but its share of members' total trade has not dramatically increased. 

That finding makes the story more nuanced. RCEP has clearly become a very large regional trading platform, but the evidence does not show that member countries are suddenly abandoning markets outside the bloc. Instead, Asian economies appear to be becoming more deeply connected to one another while remaining globally connected at the same time.

This is why I think the most useful way to understand Asia's next growth story is not to ask whether regionalisation is replacing globalisation. The more relevant question is whether the two are increasingly working together. The evidence so far points in that direction. Asia is building deeper regional supply chains, but it is also continuing to export to and import from the rest of the world.

For investors and businesses, this distinction matters. A company that sees RCEP only as a tariff-reduction agreement may miss the bigger opportunity. The more significant development is the emergence of a large regional ecosystem in which production, investment, technology and final demand increasingly reinforce each other. The rise in ASEAN+3's share of global final demand from about 20% in 2000 to 27.5% in 2024 may ultimately be more economically significant than any single trade-flow statistic because consumer demand gives supply chains a durable regional market. AMRO also finds that regional forces have become increasingly important to ASEAN+3 growth, showing that the region's economic performance is no longer determined mainly by demand from outside Asia.

My own view is that the strongest part of the RCEP story is not the headline US$6.039 trillion figure. That number is impressive, but it can easily be misunderstood because 2025 intra-RCEP trade was almost unchanged from 2022 and its share of members' total trade has remained around 59%. What I find more convincing is the combination of several different trends: ASEAN+3 has become the world's largest source of final demand, smaller Southeast Asian economies are becoming more important in supply chains, strategic sectors such as electric vehicles and batteries are being reorganised across the region, and businesses are diversifying production without abandoning global markets. At the same time, Japan's declining trade with China and South Korea and the continued growth of RCEP members' trade with non-members show that regional integration is neither automatic nor uniform. In my view, this makes the story more interesting, not weaker. Asia is not simply replacing the old model of exporting to the West with a new model of trading only with itself. It is developing a more complicated system in which regional demand, regional supply chains and global markets operate together. The real question for the next decade is therefore not whether Asia will become more important, but which Asian economies will capture the highest-value parts of that growth.
