The rise of ASEAN: What it means for global business

Regional vision backed by local knowledge.

Key takeaways:

ASEAN is gaining strategic weight, with rising FDI and trade scale, but middle-market businesses must still execute market by market rather than treat it as one bloc.

China+N strategies are expanding ASEAN’s role in supply chains as businesses seek resilience, tariff mitigation, and proximity.

ASEAN’s next decade depends on usable integration, including digital trade, payments, finance, and energy tools that reduce cross-border friction.

Businesses turn to ASEAN for supply chain diversification and resilience

The Association of Southeast Asian Nations (ASEAN) has historically been defined by rising incomes, urbanisation, and expanding consumer markets. Today, it features prominently in boardroom discussions about supply chains and long-term resilience.

As ASEAN approaches its 60th anniversary in 2027, the milestone offers a timely opportunity to look at the bloc’s evolution and what this means for multinational businesses.

The latest official statistics demonstrate ASEAN’s significant economic and demographic scale. It is home to more than 684 million people with US$4.37 trillion in goods trade and US$1.29 trillion in services trade. What’s more, the bloc’s foreign direct investment (FDI) inflows rose 8% to US$226 billion in 2024 even as global FDI fell 11%, underscoring ASEAN’s rising appeal at a time of weaker global investment.

Regional ambition needs country-specific execution

The bloc’s growing global relevance is shifting how businesses think about it. Terence Ang, Partner & Head of Advisory at RSM in Singapore, says ASEAN is “increasingly seen as both a growth market and, more importantly, a regional operating platform.”

A growth market is somewhere a business sells into. An operating platform is a place that a business structures itself around. This means decisions about entity locations, management teams, financing, compliance, data, customs, and talent are increasingly being made with ASEAN viewed as a regional system, even while execution remains country specific.

“Businesses are establishing ASEAN footprints not only to access customers, but also to diversify supply chains, strengthen resilience, improve market proximity, and build regional operating capabilities.”

“It is important to note that ASEAN does not operate as one seamless market,” says Mildred R. Ramos, Senior Partner at RSM in the Philippines. While ASEAN is commercially connected, middle-market businesses may feel operational friction unless they build the right management architecture for cross-border expansion.

“Bridging regional ambition and national regulation will be a core challenge for ASEAN over the next decade,” says Stephen Darley, Regional Leader for Asia Pacific at RSM International. “Capital is increasingly moving with regional intent, but tax, customs, labour, licensing, incentives, data, and repatriation still sit largely at the respective national levels.”

As middle-market businesses expand across ASEAN, the execution risk often comes from assuming an approach for one market will work for another.

“The most common mistake is over-simplifying ASEAN as a single market. Companies often assume they can replicate the same strategy, structure, and operating model across countries, when in reality each market has different regulatory and commercial dynamics.”

Partner & Head of Advisory, Singapore

Ramos reaches the same conclusion from a compliance perspective: “A common mistake we see is assuming that commercial similarity means regulatory similarity.” She cautions that businesses should not use one generic distributor agreement, employment template, tax assumption, or data-privacy approach across ASEAN. That is particularly relevant for middle-market organisations, where a small number of incorrect assumptions can create disproportionate cost, delay, or exposure.

The most successful businesses combine regional ambition with local discipline, which Ang describes as a “central strategy, local execution” approach. This balancing act becomes especially important as firms turn to ASEAN to reduce concentration risk in China.

China+N is driving diversification, not departure

China+1 and China+N strategies have increased ASEAN’s role in manufacturing and supply chain planning, with companies minimising dependency on a single geography. That shift is already visible in investment flows as manufacturing FDI in ASEAN grew by nearly 150% to US$44 billion in recent years. Chinese inputs, machinery, components, and intermediate goods, meanwhile, remain deeply embedded across Asia-Pacific production networks.

“What we’re seeing is a broader regional footprint, with ASEAN complementing, not replacing, China. For many businesses, that’s a risk management strategy rather than a complete supply chain reset.”

ASEAN’s appeal stems from what it can add to operational models rather than what it can remove. Angela Simatupang, Senior Partner & Chief Strategy Officer at RSM in Indonesia, says: “Cost reduction is rarely the sole objective. More commonly, companies are seeking supply chain resilience, geopolitical diversification, tariff mitigation, business continuity, customer proximity, and access to alternative talent pools.”

That makes ASEAN attractive, but it also raises the standard for execution. A regional footprint only improves resilience when a business understands the supply, trade, cost, energy, and governance implications in each market.

Ang also sees ASEAN playing a bigger part in multi-market structures: “China remains a critical part of global supply chains,” he says, “but we are seeing a broader shift towards multi-market operating models, with ASEAN playing a key role.” In practice, that means companies may use different markets for export manufacturing, services support, regional finance or headquarters functions, and access to domestic demand.

The value lies in the combination, not in treating each market as interchangeable.

Market selection is about fit, not fixed roles

For businesses, the opportunity is to identify where specific markets fit within a wider regional strategy. Ramos says organisations are increasingly driven by “value-chain fit rather than GDP alone.”

One country may be attractive for growth but less suited for a particular operating model. Another may carry higher costs but provide stronger regional coordination. Others can offer talent or sector depth that matters more than headline GDP. Across ASEAN, markets hold appeal for different combinations of sector strength, operating capability, and strategic relevance:

Singapore: Regional headquarters, treasury, finance, logistics, innovation, capital markets
Vietnam: Export manufacturing platforms, real estate, emerging high-tech growth
Indonesia: Scale, domestic demand, natural resources, growing industrial capability
Malaysia: Electronics, semiconductors, advanced manufacturing, data-centre-linked investment
Thailand: Automotive, industrial supply chains
Philippines: Services, Business Process Outsourcing (BPO), fintech, English-speaking talent, consumer demand

Simatupang notes that Indonesia is increasingly attracting attention because it brings together characteristics that long-term investors value. “With a population of more than 280 million people and a large working-age demographic, Indonesia offers both significant consumer demand and workforce depth,” she says. At the same time, she adds that successful execution in Indonesia requires businesses to navigate “regulatory complexity, varying regional conditions, and a diverse operating environment across the archipelago.”

That combination of opportunity and nuance defines ASEAN. “The issue for firms is not whether a market is good or bad, easy or hard,” says Darley. “Rather, the issue often lies in understanding what role that market should play, what controls are needed, what risks are acceptable, and how the local operating model connects to the wider regional strategy.”

Usable integration matters more than a united market

ASEAN is becoming more integrated in targeted ways. “The practical implication is straightforward,” notes Devika Shivadekar, Economist at RSM Australia. “ASEAN’s next chapter should focus less on broad declarations and more on usable integration.”

The most meaningful progress is coming through initiatives that reduce everyday barriers to doing business across borders:

Digital Economy Framework Agreement (DEFA): Makes digital trade across ASEAN easier by improving alignment on areas such as e-commerce, data flows, and digital business activity.
Quick Response (QR) code payments: Reduces the need for cash, card networks, or manual currency exchange by allowing people and businesses to use domestic payment apps for scanning and paying across borders in participating countries.
Regional Comprehensive Economic Partnership (RCEP): Gives ASEAN businesses access to a wider trade framework across Asia-Pacific, although firms still need to manage rules of origin and documentation carefully.
ASEAN Taxonomy for Sustainable Finance: Provides a regional reference point for sustainable finance, helping investors and companies compare green and transition activities more consistently across markets.
Capital market coordination: Improves access to finance and supports more consistent standards across ASEAN capital market bodies.
Energy interconnection: Supports regional power trading and the ASEAN Power Grid, pointing to a future in which electricity supply becomes more connected across borders, although this remains at an earlier stage than payments or trade.

These initiatives are intended to make expansion more navigable for businesses, while recognising the distinct characteristics of each market and how it operates.

Looking ahead, Ramos adds: “ASEAN at 70 becomes commercially more useful if integration moves from policy statements to operating tools that middle-market firms can actually use.”

ASEAN markets are keen to work together, but each country decides how policies are put into practice. Progress happens incrementally through consensus rather than through sweeping regional rules. Simatupang observes: “The vision is increasingly regional, but implementation often remains national.”

The next decade will test whether ASEAN can reduce friction

ASEAN at 60 sits between two realities. It is increasingly important as a destination for investment, manufacturing, and services as businesses adapt to an uncertain global economy. At the same time, it remains operationally uneven with national rules continuing to shape the real cost and speed of expansion.

“For middle-market firms, the opportunity is significant but not automatic. The companies best placed to benefit will be those that understand ASEAN neither as a seamless single market nor as a loose collection of unrelated economies. It is something more complex and more commercially useful: a connected but varied operating environment where each market can play a different role.”

Greater predictability and practical cross-border tools would allow businesses to scale with confidence while respecting the local realities that define execution across Southeast Asia. When ASEAN reaches 70, the measure of progress will not be whether its markets look the same, but how easily businesses can navigate their differences.
