Bolivia and Chile had severed diplomatic relations in 1962 over the Atacama border dispute, leaving Bolivia without sovereign access to the Pacific Ocean. Bolivia's longstanding ambition to regain sea access created pressure for a negotiated solution, prompting both nations' military governments to seek a bilateral agreement in the mid-1970s.
On February 8, 1975, Bolivian dictator Hugo Banzer and Chilean dictator Augusto Pinochet met at the Charaña railway station in Bolivia. They discussed a proposal under which Chile would grant Bolivia a corridor to the Pacific Ocean, with Bolivia providing Chile an equivalent area of territory along their shared border, and briefly restored diplomatic relations between the two countries.
Peru exercised its treaty-based veto over any territorial exchange involving land near its border, causing the accord to collapse. Bolivia severed diplomatic relations with Chile again in 1978, a rupture that persisted. The failure entrenched bilateral hostility, and Bolivia ultimately pursued its sea-access claim before the International Court of Justice, which ruled in Chile's favor in December 2018.
Political Outcome
The accord failed after Peru vetoed the proposed territorial exchange; Bolivia severed diplomatic relations with Chile in 1978, which remain unrestored.
