The 2025 tariff wave has accelerated an already discernible regional restructuring of manufacturing known as the “China + 1” strategy—a policy under which multinational firms retain a portion of their Chinese production base while developing complementary operations elsewhere in Asia. According to BBVA Research (2025) and Asian Development Bank Outlook (2025), more than 38 percent of surveyed firms in electronics, apparel, and machinery reported plans to diversify production outside mainland China within twelve months of the U.S. tariff expansion.

Vietnam remains the principal beneficiary of this diversification trend. The country has attracted substantial investment in electronics, garments, and furniture manufacturing, with Vietnam’s Ministry of Planning and Investment (October 2025) reporting USD 12 billion in new FDI commitments since the beginning of the year—40 percent higher than in the same period of 2024. Malaysia and Thailand have also seen a surge of mid-value manufacturing relocation, particularly in automotive parts, semiconductors, and industrial machinery, supported by competitive labour costs and improving logistics infrastructure.

India is positioning itself as a long-term alternative for scale manufacturing. The Reserve Bank of India (2025) notes a record inflow of FDI into electronics assembly, led by multinational firms seeking tariff-neutral access to the U.S. and European markets under India’s trade agreements. However, structural constraints—such as slower customs processing and higher input costs—limit India’s immediate ability to absorb the production volumes leaving China.

The Enduring Role of Re-Export Hubs

While the direct trade routes between China and the United States have contracted, re-export hubs such as Hong Kong and Singapore continue to play a critical intermediary role. Hong Kong Trade Development Council (2025) data indicate that re-exports accounted for nearly 98 percent of the city’s total exports, with a rising share of goods originating in mainland China but re-labelled or processed in third countries to mitigate tariff exposure.

Singapore, for its part, has emerged as a logistics and financial hub for regional supply-chain coordination. The Economic Development Board of Singapore (2025) highlights a notable increase in the establishment of regional procurement centres and treasury functions for multinational manufacturers operating in ASEAN. These hubs allow firms to re-route invoices, manage customs documentation, and diversify shipping origins, providing partial insulation against tariff-specific trade frictions.

However, the widespread use of re-export hubs has also attracted regulatory scrutiny. The U.S. International Trade Commission and U.S. Customs and Border Protection have intensified checks to detect “trans-shipment” practices designed to disguise the true origin of goods. This dynamic underscores that while hubs can smooth short-term frictions, they do not fundamentally alter the underlying geography of production.

Persistence of Chinese Upstream Dominance

Despite relocation trends, China retains an unrivalled position in upstream manufacturing, particularly in intermediate goods and advanced components. Input-output data compiled by the OECD TiVA Database (2025) show that over 45 percent of ASEAN’s manufactured exports contain Chinese value-added content, a ratio virtually unchanged since 2020.

Even as final assembly moves to countries such as Vietnam or Malaysia, critical components—semiconductors, displays, precision tools, batteries, and industrial chemicals—remain sourced from China. The Asian Development Bank (2025) estimates that for every dollar of manufactured exports shipped from Southeast Asia to the United States, an average of 35 cents reflects Chinese intermediate input. This interdependence limits the ability of regional economies to fully decouple and highlights that the “China + 1” model often produces re-routing, not replacement.

Case Examples of Industrial Relocation

The electronics sector provides the clearest example of ongoing reconfiguration. Major contract manufacturers have expanded production in northern Vietnam since mid-2025, assembling consumer devices and computing components previously shipped from mainland China. Similarly, Thailand’s Eastern Economic Corridor has become a hub for automotive-parts and battery-pack production, serving Japanese and Korean automakers seeking tariff-resilient export channels to the United States.

In Malaysia, semiconductor firms have increased investment in back-end assembly and testing, leveraging the country’s political neutrality and trade links with both China and the West. The Malaysian Investment Development Authority (2025) recorded a 28 percent year-on-year increase in electronics investment approvals by Q3 2025.

These developments underscore a key paradox: while physical production footprints are becoming more distributed, the informational, financial, and supply dependencies on China persist. Many “relocated” facilities still rely on Chinese tooling, engineering expertise, and logistics networks, demonstrating that the region’s supply-chain realignment remains partial and path-dependent.
