Thailand and Laos are collaborating on environmental protection and cross-border connectivity, focusing on forest fires, transboundary haze, and PM2.5 pollution. Key initiatives include implementing a joint action plan under the 2024-2030 CLEAR Sky Strategy for air-quality monitoring and fire prevention, sharing fire hotspot data and modern firefighting technology, and developing a 1.78-billion-baht bridge between Nang and Luang Prabang to boost trade and tourism. The bridge is expected to reduce travel time by 30-45 minutes and attract significant economic benefits through increased regional connectivity.
