Chile is a stable democratic republic occupying a long, narrow strip of western South America between the Andes and the Pacific, bordering Peru, Bolivia, and Argentina. It is among Latin America's most institutionally consolidated states, an active member of the Pacific Alliance, OECD, and a participant in regional bodies, while maintaining a long-standing diplomatic dispute with Bolivia over land access to the sea. The presidential system combines head of state and government in one office; Josรฉ Antonio Kast of the Republican Party leads, signaling a recent shift toward the political right after years of debate over constitutional reform and social policy. Key fault lines for readers include polarization over inequality, social spending, immigration, and the unresolved question of replacing the Pinochet-era constitution.
