In this episode, I talk with journalist and author Sebastian Strangio about the border tensions between Cambodia and Thailand that have escalated in July 2025. Sebastian is the Southeast Asia editor at The Diplomat and one of the region’s leading journalists. He’s a former reporter at the Phnom Penh Post, and the author of Hun Sen’s Cambodia (re-released as Cambodia: From Pol Pot to Hun Sen and Beyond) and In the Dragon’s Shadow, a study of China’s growing influence in Southeast Asia. 

We start with the political figure who has shaped Cambodia for decades, Hun Sen, and trace how his rise from Khmer Rouge defector to Prime Minister led to the creation of a powerful political dynasty. We then look at the handover of power to his son, Hun Manet, and what that has meant for Cambodian politics in the last two years. 

From there, we shift focus to Thailand and explore the structure of Thai politics today. Who holds power? How have coups and party shifts shaped its modern system? And how does that compare to Cambodia’s more centralized model? This helps us understand one of the key triggers of the current crisis: a leaked phone call between Hun Sen and former Thai Prime Minister Paetongtarn Shinawatra. 

We then move into the border dispute itself. We look at the long history of territorial claims, colonial-era maps, and temple flashpoints like Preah Vihear and Ta Moan. And we ask how this latest confrontation fits into broader patterns of nationalism, political theatre, and regional rivalry. Finally, we explore what role public opinion and media narratives are playing on both sides of the border.
