Chile has launched an ambitious new border security strategy aimed at reducing illegal immigration and drug trafficking along its frontiers with Bolivia and Peru. Known as the Border Shield Plan, the project includes three-metre-deep trenches, a 30-kilometre border barrier, drones, thermal cameras and other surveillance technology designed to monitor one of South America's busiest migration routes. While the government says the measures will strengthen border security, many residents remain skeptical, arguing that traffickers quickly adapt by finding new routes and bypassing physical barriers. This report examines Chile's latest border initiative, the challenges of securing hundreds of kilometres of frontier, and the ongoing debate over whether walls and barriers can effectively curb illegal migration and organized crime.
