Thailand’s 20-year Foreign Affairs Masterplan (2018–2037), or the “5S Strategy”, sets out a long-term, integrated vision for how diplomacy and international partnerships should help propel Thailand toward being a developed, stable, prosperous, and sustainable country. Rather than treating foreign policy as only “politics between states,” the Masterplan frames diplomacy as a national tool to deliver security, growth, credibility, global standing, and better public services by aligning external engagement with Thailand’s long-term development goals. 

The Masterplan organizes this vision into five strategic priorities (5S) that guide Thailand’s external relations and the expected benefits for Thai people: 

Security focuses on keeping Thailand safe from both traditional and non-traditional threats such as transnational organized crime, terrorism, epidemics, and disasters; by strengthening and diversifying partnerships, stepping up Thailand’s role in regional stability, reinforcing ASEAN centrality, and expanding cooperation at bilateral, regional, and global levels for comprehensive security. 

Sustainability emphasizes competitiveness alongside green growth, positioning Thailand as a hub for trade, investment, services, and connectivity through innovation and infrastructure, while strengthening Thailand’s role as a global partner for sustainable development, especially through development diplomacy and principles linked to the UN SDGs.

Standard aims to align Thailand’s development with international standards through effective implementation of international obligations, including human rights protection and tackling human trafficking and forced labor in supply chains, while engaging constructively in global norm-setting and sharing best practices (including through South-South cooperation). 

Status is about enhancing Thailand’s standing through soft power diplomacy, promoting Thai culture and gastronomy, maintaining global tourism leadership, strengthening Thailand’s image as a regional convening hub (“Geneva of Asia”), and developing Thai human resources so Thai people at home and abroad can access opportunities and succeed in an interconnected world. 

Synergy recognizes that modern foreign policy involves many actors, so Thailand must improve coordination and information-sharing across agencies, use technology to increase efficiency, and build partnerships with the private sector and civil society, resulting in more integrated, inclusive policy delivery and faster, more responsive public services (especially consular services).
