Port Agreements

The Port of Los Angeles has 17 sister and friendship port agreements with ports around the world.
Sister and friendship port relationships strengthen the economic and commercial bond between the respective countries, which focus on technology and operational improvements, and allow sharing components of environmental programs and policies regarding air quality, water quality and wildlife habitats to better both harbors.

A sister or friendship port agreement may also call for the sharing of various information in port infrastructure improvement, commercial facilities development, port operation and to cooperate for trade vitalization and service improvement.

Relationship with the Port of Nagoya

The Port’s longest-standing sister port agreement is with the Port of Nagoya, Japan. The Los Angeles and Nagoya Sister City Affiliation began as a part of President Eisenhower’s Citizens’ International Exchange Program in 1959. The primary goal of the sister city program is to foster mutual understanding between the people of Los Angeles and Nagoya through cultural, educational and people-to-people exchange activities. Over the decades, the two ports relationship has been celebrated by numerous visits, exchange programs and meetings.
Building on more than 60 years of collaboration, the ports of Los Angeles and Nagoya signed a Memorandum of Understanding (MOU) in 2020 to further cooperate and exchange information on projects focused on operational efficiency and environmental sustainability. This agreement established more formal cooperation and exchange of information between the two ports on various topics, including port community systems and end-to-end supply chain information sharing platforms; development and deployment of zero-emission vehicles and equipment; and other activities connecting science, industry and start-ups that could contribute to both ports’ efficiency and environmental priorities.
