The global economic landscape is entering a multipolar era characterized by a shift in the manufacturing center of gravity from the West to the East. Amidst the uncertainty of advanced countries' protectionist policies, Southeast Asia (ASEAN) is emerging as the new epicenter of economic growth as well as a space for close integration and collaboration between ASEAN and China. While global attention is focused on China’s record trade surplus projected to reach 1 trillion US dollars by 2025, ASEAN and China are instead deepening cooperation in market access, technology transfer, investment flows, and supply chain stability for the industrial and digital sectors.
China–ASEAN manufacturing collaboration can be understood through the concept of complex interdependence, developed by Robert Keohane and Joseph Nye. The theory argues that in highly interconnected economies, power increasingly derives from patterns of economic sensitivity and vulnerability within networks of trade, investment, and technology exchange rather than from military capabilities alone. In this context, ASEAN–China relations are shaped by dense economic linkages: China relies on ASEAN as a manufacturing platform, logistics corridor, and expanding consumer market, while ASEAN depends on China for capital, technology, industrial equipment, and market access.
How ASEAN–China economic interdependence works
ASEAN–China interdependence operates through multiple channels that extend far beyond government-to-government relations. Chinese firms such as BYD in Thailand, Alibaba in Malaysia, and Huawei in Indonesia build direct partnerships with local industries, while e-commerce platforms such as Lazada and Shopee connect millions of small businesses across borders. Educational exchanges and tourism also create dense social and economic linkages.
Economic issues also continue to move forward despite geopolitical divergences. Maritime differences in the South China Sea coexist with deepening economic integration, illustrated by the continued negotiation of agreements such as the upgraded ASEAN-China Free Trade Area (CAFTA 3.0). Rather than being dominated by a single security issue, the relationship is sustained by a broad range of economic and institutional ties.
Why ASEAN and China depend on each other
The interdependence between ASEAN and China is the most important variable enabling the resilience of both parties to continue collaborating, even when faced with various pressures—whether arising from global geopolitical tensions, bilateral maritime differences, or internal structural disparities. Within the complex framework of interdependence, the bilateral relationship boasts multi-layered interdependent features.
ASEAN is a strategic logistics route. China's investment in port and railway infrastructure in ASEAN serves to support the diversification of supply routes between ASEAN and China. Meanwhile, ASEAN needs China as a source of investment. Chinese direct investment in ASEAN has reached a record high, driving industrialization and job creation in the region. Besides being a source of investment, ASEAN needs China as a source of technology.
China is also a source of capital for ASEAN. Through the Belt and Road Initiative and various financing schemes, China provides capital for the much-needed infrastructure in ASEAN. Western development banks often impose stricter requirements. Many ASEAN countries face significant production capacity constraints under their existing development paths. China's large population also serves as an important market access for ASEAN. With a population of 1.4 billion and a continuously growing consumer class, the Chinese market is a major export destination for ASEAN manufactured products. Without access to the Chinese market, many ASEAN industries would lose their largest export destination.
How ASEAN-China interdependence is reshaping regional supply chains
In the manufacturing sector, verified official data shows China’s manufacturing investment in ASEAN in 2024 grew by 68.2 percent year on year, reaching US$153.9 billion, led by the electric vehicle (EV), battery, and electronics sectors, marking a shift from earlier labor intensive investment toward higher value added industries.
The distribution of investment forms a functional hierarchy in which ASEAN member states play different roles: Singapore serves as a hub for capital and regional headquarters, Thailand, Vietnam, and Indonesia function as major manufacturing spaces—Thailand in the EV supply chain, Indonesia in nickel processing for batteries, and Vietnam in electronics assembly—while Malaysia is emerging as a semiconductor stronghold with Chinese companies investing in silicon carbide wafer fabrication. These developments have strengthened sectoral interdependence in areas such as electronics, semiconductors, and EV production, where Chinese technology, equipment, and components interact with ASEAN’s manufacturing and assembly capacities.
As a result, intra-industry trade between ASEAN and China has increased, reflecting a shift from traditional commodity trade toward vertically integrated regional production networks. Institutional frameworks such as the upgraded ASEAN China Free Trade Agreement (CAFTA 3.0) and the Regional Comprehensive Economic Partnership (RCEP) further support supply chain connectivity and cross border production.
At the same time, Belt and Road infrastructure projects are accelerating physical integration: the Jakarta Bandung High Speed Railway is now operational, the China Laos Railway has increased freight capacity and reduced logistics costs, and Malaysia’s East Coast Rail Link will connect ports on the Malacca Strait with the South China Sea, enabling industries to expand into new production corridors across Southeast Asia.
Against a shifting global economic landscape, the multi-layered interdependence between China and ASEAN continues to evolve. Closer investment ties, industrial complementarity, and institutional cooperation are reshaping regional supply chains. As CAFTA 3.0 and RCEP are further implemented, both sides will continue to advance industrial upgrading and coordination, with economic interdependence remaining a key factor shaping regional economic dynamics.
