This chapter introduces the concept of the “Lao Way” as a framework for understanding peace and sustainable development in Laos. Drawing on field experience from 2021 to 2024, it argues that Laos’s approach is shaped by three interrelated elements: harmony and solidarity, animism and spirit cults, and Theravāda Buddhism. These elements are deeply embedded in daily life and reinforce social cohesion, spiritual balance, and ethical responsibility. The chapter situates the Lao experience within broader regional discourses, including “Asian values” and the “Association of Southeast Asian Nations (ASEAN) Way,” highlighting shared preferences for non-confrontation and consensus. While Laos faces significant structural challenges—fiscal dependency on China, limited institutional capacity, and unexploded ordnance (UXO)—it continues to pursue development within a model rooted in cultural identity and traditional values. The national emblem serves as a symbol of this synthesis, blending Buddhism with ecological consciousness. Recognizing the “Lao Way” is essential for understanding how peace and development are locally conceived and practiced. Rather than imposing external models, international engagement must align with these foundations to ensure legitimacy, resilience, and sustainability. The chapter concludes by offering the “Lao Way” as a provisional analytical tool for future research in Southeast Asia.
