The return of Donald Trump to the White House in 2025 presents a complex geopolitical challenge for the Association of Asian Southeast Nations (ASEAN). Trump’s previous tenure demonstrated a clear departure from multilateralism, a prioritization of bilateral transactions, and an unpredictable engagement with global allies.
ASEAN, a bloc reliant on diplomacy, economic integration, and strategic neutrality, now finds itself at a critical juncture. Trump likely brings resurgence economic uncertainty, security dilemmas and a potential erosion of ASEAN’s diplomatic unity. This essay presents a deeper analysis of the problems ASEAN faces and challenges it must navigate for Trump 2.0.
Trump’s first presidency (2017-2021) reshaped global diplomatic norms, retreating from multilateral institutions and shifting U.S. engagement toward a transactional interest-based approach. Unlike Biden’s administration, which sought to rebuild alliances, Trump 2.0 could see ASEAN further marginalized in favor of individual, deal-driven engagements. The erosion of ASEAN’s collective leverage weakens its ability to negotiate favorable terms with the U.S, ultimately creating internal strategic divisions and dilemmas among its member states. If Trump dismisses ASEAN-centric frameworks such as the ASEAN-U.S. Summit and the East Asia Summit bloc, regional influence may wane, making it vulnerable to external pressures from both Washington and Beijing.
Economic ramifications are among the most pressing concerns. Trump’s initial tenure was marked by an aggressive trade war with China, severely disrupting global supply chains and creating economic ripples throughout Southeast Asia. The potential for renewed economic hostilities in 2025 poses a threat to ASEAN’s economic stability, which is deeply intertwined with both the U.S. and Chinese markets.
While ASEAN sought to mitigate these risks through agreements such as the Regional Comprehensive Economic Partnership (RCEP), a Trump-led U.S. could impose new trade barriers or renegotiate deals favoring American interests, leaving ASEAN economies susceptible to external economic shocks. Moreover, Trump’s preference for bilateral over multilateral trade deals undermines ASEAN’s negotiating power, potentially isolating smaller economies and exposing them to predatory economic practices.
Security in the Indo-Pacific is another significant challenge. Trump’s previous presidency displayed a wavering commitment to regional security frameworks, which, if repeated, could leave ASEAN member states exposed to China’s increasing assertiveness in the South China Sea. The Biden administration reinforced freedom of navigation operations (FONOPs) and reaffirmed support for ASEAN’s territorial claims, but Trump’s return deprioritize might these efforts favor in striking of trade or investment deals with Beijing. If the U.S. scales back its military presence, China could seize the opportunity to escalate its militarization of disputed waters, further pressuring ASEAN claimants such as the Philippines, Vietnam, and Malaysia. The lack of a strong U.S deterrence could force ASEAN states into strategic difficult recalibrations with some potentially yielding to Chinese influence to ensure economic and security guarantees.
Moreover, ASEAN’s ability to maintain autonomy is strategic U.S.; amid tensions, China will be tested severely. Trump’s with the Quadrilateral Security Dialogue (Quad) comprising the U.S. Japan, India, and Australia were inconsistent during his first term. A second Trump presidency could either revive an aggressive Indo-Pacific posture or result in further disengagement, depending on his administration’s priorities. Both scenarios present challenges: an intensified Indo-Pacific strategy could pressure ASEAN states to choose between aligning with the U.S. and maintaining neutrality, while a disengaged Trump administration could leave ASEAN diplomatically stranded, exposing it to Beijing’s influence. The principle of ASEAN neutrality, long regarded as stabilizing a force in the region, may come under increasing strain as the bloc struggles to navigate shifting geopolitical dynamics.
Institutional limitations within ASEAN also pose challenges in responding to a changing U. S foreign policy landscape. The bloc’s consensus-based decision-making model, while promoting unity, often slows responses to geopolitical crises. Trump’s preference for direct bilateral negotiations could widen divisions within ASEAN, particularly between states aligned more closely with U.S. interests (such as Singapore and the Philippines) and those economically dependent on China (such as Cambodia and Laos). A lack of ASEAN-coordinated response would weaken its influence in Washington, reducing its ability to shape U. S. policies that affect the region.
Political ramifications are also a significant challenge for ASEAN. During Trump’s first term, there was a noticeable reluctance to prioritize democratic norms and human rights, with a greater emphasis on economic and security-based transactions. If this trend persists, ASEAN leaders grappling with internal legitimacy issues—like Myanmar’s junta or Thailand’s military-backed government—may experience reduced scrutiny from Washington. Conversely, democracies like Indonesia, which value strong relations with the U. S based on governance and human rights, could see their ties strained. This disparity may further fragment ASEAN’s internal cohesion as different member states navigate Trump’s foreign policy priorities through diverging strategies.
Despite these hurdles, ASEAN has opportunities to counterbalance the uncertainty of a Trump 2.0 Presidency. Strengthening intra-regional economic cooperation through RCEP and fostering deeper trade ties with the European Union could help Japan and India reduce their overreliance on U.S. markets. ASEAN can strengthen its defense initiatives through the ASEAN Defense Ministers’ Meeting-Plus (ADMM-Plus), allowing for a degree of stability that is independent of U.S. military engagement. Engaging China strategically while maintaining ASEAN’s collective stance in territorial disputes will be crucial in ensuring that regional sovereignty is not undermined.
Ultimately, ASEAN’s response to Trump 2.0 must be characterized by adaptability, unity, and strategic foresight. The bloc faces formidable challenges, including economic uncertainty, instability, security, and the erosion of multilateral diplomatic engagement. The primary obstacle remains ASEAN’s cohesion—without a unified strategy, individual states may be forced into difficult concessions that undermine regional stability.
Trump’s unpredictable approach to foreign policy adds a layer of complexity, making it imperative for ASEAN to bolster its resilience through diversified partnerships and strengthened internal coordination. If ASEAN fails to shape its regional strategies proactively, it risks being sidelined in an increasingly volatile Indo-Pacific order. The coming years will test the bloc’s ability to navigate one of its most complex diplomatic landscapes to date, demanding a recalibrated and pragmatic approach to ensure its continued relevance and stability.
