Chile clears key permit
Chile has approved the long-awaited Puerto Exterior expansion at the Port of San Antonio, clearing a major regulatory hurdle for a $4.45 billion project aimed at reshaping container capacity on South America’s Pacific coast.
The Valparaíso regional environmental commission reviewed the Outer Port of San Antonio environmental impact study on May 26, 2026, according to Chile’s Environmental Assessment Service.
The approval follows a six-year review process that included public participation, technical amendments, and indigenous consultation.
Capacity set to triple
The project will add a nearly 4 km breakwater, dredging works, yard areas, and two semi-automated terminals, each around 1,730 m long.

Once fully built, Puerto Exterior is expected to handle 6 million TEU a year and accommodate up to eight 400 m container ships at the same time.
The first phase is planned for around 2036, with 865 m of quay and an annual capacity of 1.5m teu.
Regional competition sharpens
San Antonio already handled more than 2m TEU in 2025, becoming the first Chilean port to reach that mark.
The approval comes as Peru’s China-backed Chancay port increases pressure on Pacific coast gateways competing for Asia trade. Reuters reported that China’s Xi Jinping inaugurated the deepwater port in November 2024 as part of Beijing’s South America trade push.
For carriers, shippers, and terminal operators, the question is simple: where will the next generation of Pacific services call when vessel sizes, automation, and inland links decide the route map?
