The United States’ recent tariff measures are expected to have severe consequences for Southeast Asian economies, with Vietnam and Cambodia among the most vulnerable. Both countries are heavily dependent on the US as a key export market, making them especially exposed to shifts in American demand. A UNDP report warned that Cambodia could see a 23 percent drop in US-bound exports, resulting in a one-third contraction of its entire export sector. Vietnam, facing tariffs of up to 20 percent on apparel, footwear, and electronics, risks losing nearly US$25 billion in trade. Last year, Vietnam exported goods worth US$136.5 billion to the US, making it one of Washington’s top suppliers.
Other ASEAN nations are also bracing for significant losses. Thailand’s exports to the US are projected to fall by 12.7 percent, Malaysia’s by 10.4 percent, and Indonesia’s by 6.4 percent. The region’s strong reliance on the semiconductor sector could also turn into a vulnerability, as the US considers imposing duties of up to 300 percent on chips. Analysts warned that this move could not only erode Southeast Asia’s competitiveness in the US market but also push investments back toward American soil. Additional concerns have been raised over Washington’s scrutiny of transshipped goods and its potential to create compliance challenges across the region. Smaller industries, including furniture makers in Malaysia and Singapore, are expected to be among the hardest hit.
The economic strain is expected to deepen ASEAN’s tilt toward China as both a trading partner and investment hub. Analysts noted that Washington is unlikely to compromise on strategic sectors like semiconductors, pushing Malaysia, Vietnam, and Singapore closer to Beijing. However, experts also caution that the region is unlikely to make a dramatic pivot toward China, as most Southeast Asian economies still see it primarily as a source of investment and intermediate goods rather than a major consumer of their exports. While China offers opportunities through an upgraded ASEAN-China Free Trade Area, challenges such as intense local competition in the semiconductor sector may limit gains.
Observers argue that the crisis could push ASEAN to diversify and strengthen its internal market. Free trade agreements with alternative markets such as the EU could offer relief for some nations, while greater intra-ASEAN trade may provide resilience. However, as many ASEAN economies compete in similar export sectors, integration remains difficult. Still, experts believe that if the region can upgrade into higher value-added production, the tariffs may serve as a painful but necessary catalyst for long-term economic diversification and resilience.
