Why tensions flared again—and what it means for Southeast Asia
🔍 Overview
Thailand and Cambodia have once again found themselves in the middle of a border dispute, reviving historical tensions rooted in colonial-era demarcations and cultural rivalry. While not a full-blown war, localized military deployments and political statements have alarmed the region. Let’s break down what’s happening, what caused it, and what it could mean moving forward.
🗺️ What is the Thailand-Cambodia Border Dispute?
At the heart of the tension lies a long-standing territorial claim around the Preah Vihear Temple, a centuries-old Hindu temple located near the border. The International Court of Justice (ICJ) ruled in 1962 that the temple belongs to Cambodia, but disputes over surrounding land (4.6 sq km) have persisted ever since.
