Regional trade agreements become a buffer for Asia against Trump's tariffs.

From Vietnamese Seafood to Regional Resilience: A Quiet Trade Revolution

For nearly the past 25 years, the United States has been the most stable customer for Vietnamese seafood exporters. Shrimp, catfish, and tuna have flowed steadily to the North American market. Despite occasional tariff frictions, this trade channel has maintained remarkable vitality. However, when the Trump administration's new round of tariff measures came down, Asian exporters long dependent on the U.S. market suddenly realized: it was time to find new safe havens.

Just at this critical juncture, two mega trade agreements covering most Asia-Pacific economies—the Regional Comprehensive Economic Partnership (RCEP) and the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP)—are gradually delivering on their tariff reduction commitments. For Asian businesses, this is not just an alternative to trade diversion, but a catalyst for supply chain restructuring.

Why RCEP and CPTPP?

The core logic of Trump's tariffs is "America First," and the trade barriers created thereby have put Asian exporting countries under dual pressure: on the one hand, rising access costs to the U.S. market, and on the other, increasing uncertainty in global demand. In this context, RCEP and CPTPP offer an alternative rule framework.

These two agreements cover a vast market spanning from East Asia to Southeast Asia, and from Oceania to North America. Unlike the stalled multilateral negotiations under the WTO framework, RCEP and CPTPP feature deeper tariff concession commitments and more specific rules of origin. More importantly, they are reducing tariffs gradually according to schedule, rather than opening up all at once. This "incremental" characteristic enables businesses to adjust supply chains in a planned manner without falling into chaos.

But this buffer is not evenly distributed. As trade experts have pointed out, there are significant differences in the benefits gained by different industries and different countries. Take Vietnamese seafood as an example: CPTPP members include major seafood-consuming countries such as Japan, Canada, and Australia, and these markets are providing Vietnamese exporters with alternatives outside the United States. However, for exporters dependent on specific U.S. product categories, the transition is not easy.

Industry Imbalance: Who Is Reaping the Dividends?

The tariff reductions under RCEP and CPTPP cover a wide range of fields from agricultural products to industrial manufactured goods, but the benefits do not arrive simultaneously.

Time-sensitive goods such as agricultural products and seafood benefit more easily from the agreements—lower tariffs directly enhance price competitiveness, while shorter shipping distances (such as from Vietnam to Japan) keep logistics costs manageable. In contrast, industries with complex supply chains, such as automobiles and electronics, need more time to adjust origin compliance, especially when components come from non-member countries.

This imbalance is equally evident at the country level. Developed countries such as Japan and Australia have greater market openness under CPTPP, while emerging economies like Vietnam and Malaysia benefit more as exporters. RCEP, on the other hand, is led by China and ASEAN, and its internal tariff reduction arrangements have created new growth points for intra-regional trade. But this also means that some member countries may be at a relative disadvantage due to differences in industrial structure.## Supply Chain Restructuring: From "China+1" to "Regional Multi-Center"

Tariff pressure is reshaping Asia's manufacturing landscape. Over the past few years, many multinational companies have pursued a "China+1" strategy, relocating some production capacity to Vietnam, Thailand, or Indonesia. Now, the rules of RCEP and CPTPP are upgrading this migration into a "regional multi-center" layout.

The reason lies in the rules of origin cumulation. Under these rules, when products circulate among multiple agreement member states, the origin value can be calculated cumulatively. This means that a company can produce core components in one member state, assemble finished products in another, and ultimately enjoy preferential tariff treatment under the agreement. This greatly enhances the flexibility of supply chain layout and extends the concept of the "Asian factory" from a single country to an entire regional network.

Vietnam, as one of the beneficiaries of this trend, is attracting substantial investment in electronics and textiles. But this comes with infrastructure bottlenecks and skills shortages. Meanwhile, Malaysia and Thailand are also actively competing for the status of regional production hubs. The final outcome of this competition will determine the geographic distribution of Asia's supply chains over the next decade.

Long-Term Concerns: The US Factor and the Future of Free Trade Centers

Although RCEP and CPTPP provide a buffer for Asia, the "economic weaponization" of tariffs under Trump is causing deep damage to Asia's free trade system. ASEAN, as a core node of the global free trade network, has seen its position cast into shadow by the unpredictability of US policy.

More critically, these agreements are not sufficient to fully replace the US market. For many Asian exporting countries, the US remains an indispensable destination for end-consumer demand. Trade diversion can only alleviate short-term pain but cannot resolve the fundamental problem of shrinking demand.

As a result, Asia's business ecosystem is undergoing a structural adjustment: on the one hand, intra-regional trade cohesion is strengthening, with RCEP and CPTPP forming a de facto "Asian economic safety belt"; on the other hand, external uncertainty is forcing companies to place greater emphasis on diversified market layouts. In the future, companies that can simultaneously leverage the benefits of these agreements and flexibly adjust their supply chains will gain a competitive advantage amid this transformation.

Conclusion: A Buffer Is Not a Safe Haven

Asia's major trade agreements are proving their value as buffers against tariff shocks, but they are not all-purpose safe havens. The uneven distribution of benefits, the complexity of rules of origin, and the continued interference of US policy are all reminding companies and policymakers that truly lasting resilience comes from deep regional integration and diversified supply chains. For the Asian economy, this is both a challenge and an opportunity to redefine its role in globalization.
