Chile is undertaking significant measures to manage irregular immigration by constructing walls along its border with Peru, with some barriers reaching heights of up to five meters. This initiative is part of President José Antonio Kast's "Border Shield Plan," which aims to extend up to 500 kilometers and incorporates advanced technology including drones, sensors, and military presence to enhance border security. Kast argues that the military's involvement reflects the majority sentiment of Chileans, emphasizing that issues like drug trafficking and organized crime transcend political affiliations.

More than 330,000 foreign nationals are currently living in Chile without proper documentation, prompting the government to focus on stricter immigration controls. The construction of these barriers has been framed within the broader context of national security and public safety, as officials link irregular immigration to increased crime and drug-related issues. This stance has sparked debates within Chilean society about immigration reform and the treatment of undocumented immigrants, as well as the implications for human rights along the border.

President Kast's controversial approach reflects broader regional trends in the treatment of immigration and border security, as countries respond to influxes of migrants and refugees. While this plan aims to deter illegal crossings, it raises ethical concerns regarding the treatment of individuals seeking asylum or better opportunities. As the situation develops, it remains to be seen how these measures will impact Chile's international relations and its domestic social fabric, particularly in terms of humanitarian considerations and community relations with immigrant populations.
