Chile's President, José Antonio Kast, has begun construction on a border barrier along the northern border with Peru, marking a significant milestone in his fight against illegal immigration and drug trafficking. This is part of Kast's policies, which aligns with US President Donald Trump's efforts to stem illegal immigration. The country's border with Paraguay is estimated to cover around 180km and an additional 900km, though the interior ministry has stated that the barrier will only cover roughly half of this.
