As the 46th ASEAN Summit confronts global economic uncertainty, the most strategic response to President Donald Trump’s tariff-driven approach is disengagement, not negotiation or appeasement (Rodrik, 2025). Ignoring Trump is not passivity, it is strategic defiance. By refusing to be drawn into asymmetrical negotiations, ASEAN can protect its interests and let the costs of protectionism fall squarely on the US economy.

Trump’s depiction of China, Japan, South Korea, India, and ASEAN as job thieves is not just misleading—it is a deliberate distortion of economic reality. From 2021 to 2024, US unemployment averaged just 3.8 percent, among the lowest rates not only in the developed world, but globally, exposing the falsehood that foreign economies are siphoning off American jobs. In fact, the US economy soared to a record $29.3 trillion in 2024, retaining its position as the largest economy, with per capita income of $86,000.

Structurally, 81 percent of US GDP stems from services, which employ 79 percent of American workers—91 percent when including self-employed. Manufacturing, though politically resonant, accounts for only a sliver of employment. Tariffs, particularly against Asia, under the guise of “saving jobs,” distort this reality and risk harming the very global networks that power US growth.

For decades, ASEAN has contributed significantly to US prosperity. In goods, ASEAN’s supply of semiconductors and machinery is critical to sustaining US manufacturing competitiveness. At the same time, the region’s demand for American aircraft and defense equipment supports thousands of high-skilled jobs across the United States. In services, ASEAN is a major destination for US exports, ranging from finance and education to digital platforms, contributing significantly to America’s trade surplus. In 2024, the US recorded a $24.4 billion services surplus with ASEAN. More broadly, US services exports reached $1.11 trillion, while imports totaled $812.2 billion, yielding a global services surplus of $293.4 billion (Bureau of Economic Analysis). On investment, US firms channeled $328.8 billion into ASEAN in 2024 alone, accounting for 22.5 percent of total foreign direct investment into the region.

Yet, Trump’s tariff aggression risks unraveling this mutually beneficial relationship. Punitive tariffs risk alienating a trillion-dollar trade partner, disrupting supply chains, and weakening America’s own economic prospects. For over five decades, ASEAN has anchored US prosperity—economically, strategically, and diplomatically—by supplying essential intermediate goods, absorbing US services exports, and generating trillions in annual revenue for American companies operating throughout the region.

How, then, should ASEAN respond to Trump’s destructive approach?

First, ASEAN should lead with principles. Trump’s exploitation of trade in goods imbalances to justify tariffs must not be rewarded with preferential treatment. Disengagement from Trump is a firm reaffirmation of ASEAN’s core values: non-alignment, multilateralism, and mutual respect. ASEAN should underscore its unwavering commitment to rules-based trade and regional stability. It remains open to partnerships with any country that respects international norms and embraces equitable cooperation.

By insisting on WTO principles of reciprocity and MFN treatment, ASEAN rejects Trump’s zero-sum logic. These principles were reaffirmed in the ASEAN Leaders’ Statement of 26–27 May 2025—a unified rejection of discriminatory trade practices. ASEAN must also partner with other regions to uphold these rules. In an era of growing economic fragmentation, ASEAN’s adherence to multilateralism offers one of the few remaining anchors of rules-based global trade.

Second, ASEAN must mobilize the American business community, whose long-term interests lie in open, stable markets. These companies have profited enormously from ASEAN's openness. It is time they defend the very conditions that enabled their success.

From Boeing to Apple, Microsoft, IBM, and Intel; from Freeport, ExxonMobil, and Chevron to platforms like Starlink; from global consumer names like McDonald’s, Coca-Cola, Nike, and Unilever to banks like Citibank, Visa, and MasterCard; from insurers AIG and Chubb to law firms Skadden and Baker McKenzie and consultancies like McKinsey and BCG—these firms flourish on open markets and regional cooperation.

Yet if influential corporations, like Elon Musk’s Tesla and Starlink, or Meta, which owns Facebook and Instagram, whose leadership aligns with Trump’s nationalist agenda, or media outlets like Fox News, which amplify protectionist rhetoric, continue to disregard ASEAN’s strategic relevance, the region must take note. These firms must harness their influence in Washington to counter economic nationalism. If they fail to speak up—or worse, remain complicit—ASEAN is right to reconsider the privileged access they enjoy in its markets.

ASEAN should make clear that market access is not a blank check. In today’s contested global economy, partnerships must be reciprocal. If US firms benefit from ASEAN’s openness but fail to defend the frameworks that enable it, ASEAN has every right to reassess their privileged access.

Last, ASEAN should let the US deal with the consequences of its own policies. Trump has made clear, through sweeping tariffs and nationalist rhetoric, that he has little regard for ASEAN, or for America’s own long-standing allies, including the EU, Canada, Japan, and South Korea. He is unlikely to change.

He responds neither to diplomacy nor to data, but only to two constituencies: his domestic political base and a narrow circle of business elites. So let them feel the impact. If Trump slaps tariffs on ASEAN, it will be US firms, those dependent on Southeast Asian supply chains, who will bear the consequences: higher costs, logistical delays, and eroded competitiveness. Ultimately, they may be the only voices he listens to.

Trying to reason with Trump is a dead end. ASEAN should instead invest in building economic resilience: deepen regional integration, diversify trade partners, and expand strategic alliances. Let the pressure come from within. This is not a retreat, it is strategic discipline. Sometimes, the most strategic move is to stand back and “let the costs of bad policy speak louder than diplomacy ever could”.

To move forward, the 46th ASEAN Leader Summit in Kuala Lumpur (26–27 May), followed by the ASEAN–GCC–China Economic Forum (27–28 May), offers a critical window for ASEAN to assert a bold economic agenda. The region must double down on intra-ASEAN trade, fully utilize the ASEAN+1 FTAs and Regional Comprehensive Economic Partnership (RCEP), strengthen ASEAN+3 with China, Japan, and Korea cooperation, and deepen strategic ties with partners across the EU, Middle East, Eurasia, Latin America, and Africa.

Diversifying not only trade and investment but also currency use and payment systems will be essential to building a more autonomous and future-ready ASEAN.

As Trump Turns Inward, ASEAN Must Turn Outward.
