The 28th of October 2025 witnessed H.E. Mr. Sihasak Phuangketkeow, Minister of Foreign Affairs of Thailand, representing H.E. Mr. Anutin Charnvirakul, Prime Minister of Thailand, at the 5th ASEAN-Australia Summit held on the sidelines of the 47th ASEAN Summit in Kuala Lumpur, Malaysia. The meeting underscored a key element of Thailand’s foreign policy – a concerted effort to maintain strategic alignment within the Association of Southeast Asian Nations (ASEAN) while bolstering partnerships with significant regional actors, most notably Australia. This event, and the preceding discussions, reflect evolving geopolitical trends impacting Southeast Asia’s security and economic landscape. The summit, centered around the 20-Year “5S” Foreign Affairs Masterplan – Stability, Security, Sustainability, Synergy, and Strategic Partnerships – highlights Thailand’s prioritization of long-term, multifaceted engagement within the region.
Historical Context and the ASEAN-Australia Relationship
The ASEAN-Australia Dialogue Relations, established in 1975, evolved from a primarily trade-focused relationship to encompass broader security and development cooperation. Initially, Australia’s interest stemmed largely from economic considerations, particularly access to the burgeoning Southeast Asian markets. However, following the 9/11 attacks and the subsequent rise in regional instability, the partnership deepened, integrating security concerns, counter-terrorism efforts, and maritime security strategies. The 2003 ASEAN-Australia Strategic Partnership Framework further formalized this relationship, acknowledging the shared commitment to regional peace, stability, and economic prosperity. Data from the Australian Department of Foreign Affairs and Trade (DFAT) indicates that bilateral trade between Australia and ASEAN countries has steadily increased over the past decade, reaching approximately $85 billion in 2024, demonstrating the enduring economic ties.
Key Discussion Points and Thailand’s Proactive Diplomacy
The discussions at the Kuala Lumpur summit centered on several critical areas. First, a significant focus remained on strengthening cooperation under the ASEAN-Australia Strategic Partnership, particularly concerning security. This included a renewed emphasis on maritime security, given increasing concerns over territorial disputes in the South China Sea and the rise of non-state actors exploiting maritime vulnerabilities. Second, economic cooperation was a core element, with Thailand pushing for enhanced trade and investment flows through existing frameworks like the AANZFTA (Australia-New Zealand Free Trade Agreement) and the Regional Comprehensive Economic Partnership (RCEP). A notable proposal from Minister Phuangketkeow was the convening of an ASEAN-wide CEO Forum, aiming to foster closer collaboration between Australian and ASEAN businesses and address regulatory hurdles. Furthermore, Thailand proposed expanding Australia’s Landing Pad innovation offices – established to support startups – across the ASEAN region, reflecting a strategic interest in promoting innovation and technological development.
Third, Thailand reiterated its commitment to people-to-people cooperation, recognizing its significance in fostering mutual understanding and strengthening ties. This included support for ASEAN’s implementation of the Five-Point Consensus, particularly concerning the situation in Myanmar, alongside continued investment in initiatives through the ASEAN Centre for Public Health Emergencies and Emerging Diseases (ACPHEED) and the ASEAN Centre for Active Ageing and Innovation (ACAI). According to a report by the Lowy Institute, Australian investment in Thailand’s healthcare sector has increased by 18% in the last three years, partly driven by initiatives funded through the ACPHEED.
Shifting Geopolitical Landscape and Future Implications
The summit’s outcome, adopting the ASEAN – Australia Joint Leaders’ Statement on Conflict Prevention and Crisis Management, reflects a broader trend of increasing regional tensions. The ongoing conflict in Myanmar, coupled with heightened strategic competition between major powers – notably the United States, China, and Russia – poses significant challenges to regional stability. Looking ahead, Thailand’s strategic alignment will be crucial in navigating these complexities. Short-term (next 6 months), Thailand is likely to continue advocating for a multilateral approach to regional security, utilizing the ASEAN platform to mediate disputes and promote dialogue. Long-term (5-10 years), Thailand’s role as a stable and reliable partner within ASEAN will be increasingly important. However, the potential for heightened geopolitical competition – particularly if China’s influence grows further in Southeast Asia – could test the robustness of the ASEAN-Australia relationship and necessitate a re-evaluation of Thailand’s strategic priorities.
Expert commentary from Dr. Eamonn Harrison, Senior Fellow at the Griffith Asia Institute, suggests, “Thailand’s ability to maintain a ‘neutral’ stance while advocating for ASEAN unity will be the key to its long-term strategic success. The ‘5S’ framework provides a valuable roadmap, but its implementation will depend on Thailand’s deft diplomacy and the willingness of its partners to embrace a shared vision for the region.”
