Situated in the heart of Southeast Asia, Thailand occupies a crucial geopolitical space in the region and is a major gateway to ASEAN markets. For years, it has maintained a balancing act between the U.S., its formal treaty ally, and China, its largest trading partner. But Thailand’s most recent coup—the 19th since 1932—has chilled the U.S.-Thai relationship, leaving Bangkok closer to Beijing. In his new book, Thailand: Shifting Ground Between the US and a Rising China, author Benjamin Zawacki argues that the United States needs to reexamine this critical alliance before it is usurped by a rising China. Listen to this week’s Asia Unbound podcast to hear why and how the United States should reinvigorate this important relationship.
