Bharis Senivongse “Bridging Oceans and Diplomacy: Geopolitics of 21st-Century Bamboo Diplomacy on Thailand’s Kra Isthmus Infrastructure Projects”

The logistics infrastructure projects on Thailand’s Kra Isthmus, which connects two oceans, demonstrate the strategic use of resources for geopolitical purposes, particularly in foreign policy. Historically, the Thai government has instrumentalized these projects to manage relationships with global powers; this reflects the adaptive nature of bamboo diplomacy. Under Prime Ministers Prayuth Chan-o-cha (2014–23) and Srettha Thavisin (2023–24), this strategic approach still persisted. This paper examines the geopolitical significance of the Kra Isthmus projects, focusing on their role in foreign policy within practical geopolitics. By analyzing published interviews of key figures related to the infrastructure projects, actions of Thai and international stakeholders, and commentaries about geopolitical situations from reputable think tanks, this research applies a practical geopolitical reasoning framework adapted from Gearóid Ó Tuathail (2002b) to the international relations concept of bamboo diplomacy. It highlights the Thai government’s efforts to use the Thai Canal and Thai Land Bridge projects to balance international relations, enhance national interests, and avoid interstate conflict.
