Overview
- Excavators and troops began work at Chacalluta on the Peru line and at Colchane on the Bolivia frontier, with President José Antonio Kast inspecting the sites.
- Plans call for trenches about 3 meters deep and walls up to 5 meters high at strategic points, with potential expansion across hundreds of miles.
- Kast says the objective is to stop irregular crossings, drug trafficking and organized crime, citing extensive smuggling routes and large flows of stolen vehicles into Bolivia.
- The government has designated vulnerable stretches as a military zone, issued emergency decrees on border control and deportations, and named Alberto Soto as a special border commissioner.
- The Border Shield pairs barriers with surveillance drones, thermal cameras, biometrics and watchtowers, proposes a 3,000‑member force, and faces legal objections from rights groups and a divided Congress.
