This study examines local perceptions on the proposed reopening of Thailand–Cambodia land border crossings, focusing on public support, economic impacts, security concerns, confidence in peaceful coexistence, and preparedness for the reopening. The findings indicate that economic necessity creates a strong underlying rationale for reopening, but security perceptions, confidence, and the information environment remain critical constraints. Importantly, local communities generally distinguish between reopening being necessary and being urgent: they recognize the economic and practical importance of restoring cross-border connectivity, but do not necessarily support immediate or unconditional reopening.
