As of April 21, 2025, Trump’s tariff policy has become unbearable for the American public. He imposed a 245% tariff on US imports from China, while placing a 90-day freeze on tariff hikes for roughly 70 countries, including the 10 ASEAN nations.

Trump has once again wielded tariffs as a bargaining chip, under the misleading pretence that they are paid by foreign governments and will miraculously restore American jobs. This narrative is not only false — it is economically harmful. His tariff aggression toward ASEAN is not just deeply disappointing; it is profoundly destabilising for the global economy.

Over the past 50 years of economic partnership, ASEAN has played a meaningful role in America’s economic ascent. The average income of Americans has risen from around $7,000 in the 1970s to $86,000 today (World Bank, 2024). This progress has been built on mutual benefit and shared growth — anchored in a predictable, rules-based multilateral trading system, not transactional or unilateral policies. For decades, ASEAN has been a steadfast and constructive partner of the US, supporting its growth through trade, investment and supply chain integration.

First, in trade in goods — particularly in the manufacturing sector — American manufacturers no longer operate in isolation. East Asia, including ASEAN — often accused by Trump of “stealing” American jobs — has, in fact, played a vital role in strengthening the US economy. ASEAN supports American manufacturing by providing access to high-quality, competitively priced inputs, and efficient supply chains. These are the very ingredients that keep American industries globally competitive.

Most rely heavily on intermediate goods — components and raw materials — sourced from global partners. ASEAN plays a pivotal role in this system, supplying high-quality, competitively priced inputs and enabling efficient supply chains. These are not marginal contributions — they are central to the global competitiveness of US industries. They reduce production costs, enhance operational efficiency and spur innovation. By ensuring access to cost-effective inputs, ASEAN helps sustain millions of American jobs and reinforces the very foundation of the US economy.

Second, consider trade in services — the true engine of the U.S. economy, which accounted for 81% of GDP in 2024. US services exports reached a record high of $1.03 trillion that year, with ASEAN countries contributing an estimated $330 billion, or roughly 32% of the total. This reflects not only the depth of economic integration between ASEAN and the US, but also the region’s growing role as a key market for American innovation, finance, education, digital platforms and professional services. ASEAN is also one of the fastest-growing regions, spending billions of US dollars annually on education and tourism in the US.

Moreover, ASEAN has long been a crucial partner in US defence-related trade. Beyond military procurement, Indonesia’s landmark deal with Boeing in 2012 — then the largest single aircraft transaction in the company’s history, valued at $22 billion — underscores the region’s strategic economic weight. With a rapidly growing middle class and surging demand for air travel, Southeast Asia is emerging as one of the world’s most dynamic aviation markets.

Third, in terms of investment, American firms — from mining (ExxonMobil, Chevron and Freeport-McMoRan), banking and payments (Visa and Mastercard), insurance (Chubb and Liberty Mutual), electronics (IBM, General Electric and Intel), electric vehicles (Tesla), telecommunications (Starlink), and e-commerce and digital platforms (Amazon and Meta), to consumer goods (Johnson & Johnson, Procter & Gamble), and food and beverages (Starbucks, McDonald’s, Coca-Cola and PepsiCo) — are deeply embedded in the ASEAN region.

ASEAN’s contribution to US investors is not peripheral; it is central to America’s economic strength. The region generates trillions of dollars in profits for US companies each year, fuels their global expansion, and helps sustain the United States’ position as a leading economic power — all while supporting millions of jobs at home.

Last, ASEAN’s success has been strengthened by a network of economic partnerships built over the past two decades, alongside political and economic stability, and investments in education and infrastructure. Key milestones include the ASEAN Free Trade Area (AFTA) established in 1992, and several ASEAN+1 Free Trade Agreements signed between 2010 and 2015 with important partners. The Regional Comprehensive Economic Partnership (RCEP), the world’s largest trading bloc, came into effect in January 2022, uniting ASEAN with Australia, China, Japan, South Korea and New Zealand. ASEAN also engages with the US through the Trade and Investment Framework Agreement and the Expanded Economic Engagement Work Plan, both aimed at deepening trade, investment and digital cooperation.

Trump’s tariff confrontation is both unjustified and detrimental to the global economy. This is not a stance against US businesses or the American people, but a direct response to a destructive policy that threatens decades of US-ASEAN cooperation and shared growth. In response, ASEAN member states issued the ASEAN Economic Ministers’ Joint Statement on April 10, 2025, reaffirming three core principles.

First, ASEAN underscored its commitment to a predictable, transparent, free, fair, inclusive, sustainable and rules-based multilateral trading system, with the WTO at its centre.

Second, it pledged to strengthen intra-regional integration.

Third, ASEAN emphasised the need to maintain strong, mutually beneficial trade and investment relations with key partners, while also expanding engagement with emerging regions such as the Middle East, Eurasia, Latin America and Africa.

ASEAN has consistently maintained that it does not and will not take sides. The region remains committed to positive, inclusive engagement in trade, investment and technology — treating all partners as equally important.

For ASEAN, the US is as vital as China, Japan, South Korea, Australia, the EU and others. Mutual respect, openness and constructive dialogue are the cornerstones of ASEAN’s external economic relations. It has reaffirmed its stance on maintaining constructive engagement, grounded in the principles of sovereignty, multilateralism and balanced development.

There is no question: ASEAN is not merely a partner to the US — it is a pillar of American prosperity and a cornerstone of global economic stability. While many of Trump’s core supporters remain unaware — or indifferent — to the rising costs of inflation, job losses and a plunging stock market, the damage to America’s image and its relationships with the rest of the world, including ASEAN, may prove lasting. Trump’s disregard has cut deep — and the consequences may not be undone.
