Chile.

Chile’s foreign policy under President José Antonio Kast is likely to be more security-forward, market-oriented, and explicitly pro-Western than under recent administrations, but it is still constrained by strong institutional continuity in the foreign ministry, trade-dependent economic interests, and Chile’s long-standing preference for legalist multilateralism in the UN system and regional diplomacy [La Tercera](https://www.latercera.com/), [OECD Chile profile](https://www.oecd.org/chile/), [UN Member States: Chile](https://www.un.org/en/about-us/member-states/chile). Chile is a unitary presidential republic, and the president sets overall foreign-policy direction, but execution runs through the Ministry of Foreign Affairs and a professional diplomatic corps that has historically defended continuity on trade, treaty commitments, Antarctic policy, and maritime and border issues [Government of Chile](https://www.gob.cl/), [Ministry of Foreign Affairs of Chile](https://minrel.gob.cl/). That decision structure matters: campaign rhetoric can shift emphasis, but Chile’s external behavior usually tracks survival and economic interests first, especially stable borders, open sea lanes, export access, and credibility with investors [World Bank Chile overview](https://www.worldbank.org/en/country/chile/overview), [APEC Chile economy profile](https://www.apec.org/).

Chile’s core interests are unusually clear. At the survival tier, it prioritizes territorial integrity, Antarctic claims, maritime rights in the Pacific, and a stable northern frontier, especially in relation to irregular migration and transnational crime flows crossing from the Andean corridor [Ministry of Foreign Affairs of Chile](https://minrel.gob.cl/), [International Court of Justice, Obligation to Negotiate Access to the Pacific Ocean (Bolivia v. Chile)](https://www.icj-cij.org/case/153). At the regime-security and domestic-order tier, a Kast government would place much more weight on border control, policing cooperation, and anti-organized-crime diplomacy than center-left governments did, reflecting his public emphasis on security as the organizing theme of state policy [Reuters](https://www.reuters.com/), [La Tercera](https://www.latercera.com/). At the economic tier, Chile remains structurally dependent on trade openness: it is one of Latin America’s most globally integrated economies, belongs to the OECD, APEC, and the Pacific Alliance, and has built its external posture around predictable rules for copper, lithium, agri-food, services, and investment flows [OECD Chile profile](https://www.oecd.org/chile/), [APEC member economy: Chile](https://www.apec.org/about-us/about-apec/member-economies/chile), [Pacific Alliance](https://alianzapacifico.net/en/). That makes abrupt ideological realignment costly. Even if official messaging hardens, Santiago still has strong incentives to protect access to Asian demand, North American capital, and multilateral dispute-settlement mechanisms [World Bank Data: Chile](https://data.worldbank.org/country/chile), [IMF Chile page](https://www.imf.org/en/Countries/CHL).

Chile’s key bilateral relationships follow that hierarchy. The United States is a central economic and strategic partner, anchored by the U.S.-Chile Free Trade Agreement and deep cooperation on commerce, science, and security issues [Office of the United States Trade Representative: Chile FTA](https://ustr.gov/trade-agreements/free-trade-agreements/chile-fta), [U.S. Department of State: U.S. Relations With Chile](https://www.state.gov/u-s-relations-with-chile/). China is also indispensable because it is Chile’s largest trading partner, which creates a durable constraint against fully ideological alignment with Washington on supply chains, critical minerals, or technology policy [Subsecretaría de Relaciones Económicas Internacionales de Chile](https://www.subrei.gob.cl/), [Reuters](https://www.reuters.com/). In South America, Peru is strategically important because Chile has invested heavily in keeping the relationship legally managed after maritime litigation and because both states share interests in Pacific trade and regional stability [International Court of Justice, Maritime Dispute (Peru v. Chile)](https://www.icj-cij.org/case/137), [Ministry of Foreign Affairs of Chile](https://minrel.gob.cl/). Bolivia remains the sharpest persistent bilateral friction because access-to-sea narratives continue to shape political discourse even after the ICJ rejected Bolivia’s claim that Chile had a legal obligation to negotiate sovereign access to the Pacific [International Court of Justice, Bolivia v. Chile](https://www.icj-cij.org/case/153). Chile also works through practical ties with Colombia and Mexico inside the Pacific Alliance, where trade facilitation and outward-facing integration have generally mattered more than ideological coordination [Pacific Alliance](https://alianzapacifico.net/en/), [OECD Chile profile](https://www.oecd.org/chile/).

In regional and multilateral forums, Chile tends to behave as a legalist middle power rather than a bloc disciplinarian. It is a founding UN member and active in the UN system, while its memberships in the OECD, APEC, CELAC, and the Pacific Alliance show a pattern: Chile joins venues that expand market access and diplomatic reach without locking itself into hard ideological camps [UN Member States: Chile](https://www.un.org/en/about-us/member-states/chile), [OECD Chile profile](https://www.oecd.org/chile/), [APEC member economy: Chile](https://www.apec.org/about-us/about-apec/member-economies/chile), [CELAC](https://celac.rree.gob.sv/). In UN voting, Chile has often aligned with the broad Latin American preference for international law, humanitarian language, and support for multilateral institutions, but it has also shown willingness to criticize authoritarian governments in the region more openly than some CELAC partners, particularly on Venezuela and Nicaragua under previous governments [UN Digital Library](https://digitallibrary.un.org/), [Human Rights Council voting records](https://www.ohchr.org/en/hr-bodies/hrc), [Reuters](https://www.reuters.com/). A Kast government would likely sharpen that pattern by voting more consistently with the U.S. and other conservative or center-right governments on questions framed around democratic backsliding, border security, and crime, while still defending UN procedures and treaty law where Chile sees institutional value [UN Digital Library](https://digitallibrary.un.org/), [U.S. Department of State: U.S. Relations With Chile](https://www.state.gov/u-s-relations-with-chile/).

Chile’s most analytically useful divergence is that it often breaks not with the West, but with parts of Latin America
